Really like the way this video just got stuck in, no idents, intros, product placement or requests to subscribe, turn on notifications etc so refreshing. Come on 100K subs, so close.
Thank you! 🙏 I’ve been “getting to the main part of the content” faster and faster over the years so thank you! Glad you noticed! Always trying to edit the videos and improve them everytime! And always open to feedback! I know literally 5 mins ago, 100 subs to go! 🥳🥳🥳
Thanks so much . I just received my Mercedes. Didn’t know what the yellow circle ,with the A inside was. It was my battery. Had not been driven for about two weeks. Thanks again.
I had the battery in my GLC250 replaced under warranty to correct the failure of the start/stop function. Great to understand that there are other causes as well. Thanks Nick. Great video!
Thanks for this great video. I am having trouble with my start/stop at the moment. It doesn't start to work until around 4pm even though it's on the road all day working. At least I can rule this list out when I see mercedes later on this month. Love your videos Nick. Keep it up 😁
Great video again and a good explanation.I do a lot only driving in the city and its not working , but when i drive on the motorway it works direct , thx again 👍
Another good one Nick. I remember as an ax Fiat mechanic left hand Ritmo ES had stop start around 1982 really astonished me at the time they weren’t good starters in the first place😂 An economy model called the "ES" ("Energy Saving") was also available, it featured an early start-stop system. It featured some detail modifications to the aerodynamics, an optimised (higher compression ratio and different valve timing) version of the 1301 cc engine rated at 65 hp (48 kW), an engine shut off system (when idling) and electronic ignition.
Thanks I tend to switch mine off if I remember. It only works about 20% of the time, so I find it so unpredictable it’s actually annoying and unexpected when it does work.
I've had my merc for 6 months now, I think it has only worked 2 or 3 times during that time! Not that I am bothered as have always found the feature annoying in other cars.
@@npoleary I did! The whole playlist was amazing, also idk why but your voice makes it even better JUST ALL AROUND A SOLID 10🙏🏻🙏🏻 Im now in said GLC300 and these have been SO helpful omg, there’s so many stuffy old guys putting these videos out and half of them seem like they don’t know what they’re talking about so I really appreciate the educated way you get information across while being easy to understand even for someone who’s never driven any car in their life lol. Keep on being awesome!💕
Awh thank you! 🙏 Well I’ve got a few Mercedes tutorials lined up soon! And I am thinking another tips and tricks video is overdue so I’ll see what I can do! 😛
As a reminder for folks who leave their cars sit for extended periods. Some MB models have a standby mode that will slow the battery(s) drain. Check your owner manual to see if your car supports this mode. This is really helpful if you don't have easy access to an outlet for a trickle charger to keep the battery topped up.
Start stop system is the most hated thing in modern car. All time when I remember I try to turn off this system. Start/stop system makes a negative impact on your engine and it’s annoying for a driver. Savings from fuel are minimal but cost of repairs engine after few years can be huge.
I beg to differ. Stop start systems are designed to do so and and there are no reports of repairs caused by it. If you know of any, I’d be very thankful if you could point me to them. Stop start systems usually have a starter-generator instead of separate starters motors and alternators. The savings are very real. My car counts the time the engine is turned off from the time it got last fuelled. It adds up to about 1.5 hours per fill tank! That’s much more than I’d ever imagined.
@@Conservator. The engine is most destructive when starting. When driving in a crowded city with the existing Start-Stop system, the engine starts up to 20-30 times during the driving sequence. It will also be destructive to the turbocharger, battery or starter …
@@LukaszOlszewski An engine has the most wear when cold started because most of the oil will have dripped down. The stop/start system will only kick in when the engine is warm. The duration of the stops is too small for oil deprivation to occur. The engine is stopped just before ignition and it will hardly take any effort by the starter/generator to get the engine going again. Do you have reports of excessive wear and tear from stop/start systems?
Great content and professional. I used this video as a checklist list to make sure I wasn't missing anything as my start/ stop is annoyingly temperamental. 9 times out of 10, it doesn't work. I've had the battery tested, and apparently, it's ok.
I can save fuel and emissions but of course depends on when it was made. My first car with start / stop years ago took like a whole 2 seconds to start but cars these days start very fast!
Nice one Nick! Mine doesn’t work but I find this a blessing. I put mine down to having a tracker and two dashcams front and rear. I get the Mercedes me app complain about once a month that the battery is critical. Which means my start stop pretty much stays off all the time.
In the case of the Mercedes you still have the situation of stopping at a stop sign and the camera being able to read the sign, it also does not activate the start/stop
I've always found autos with stop/start are irritating to drive in traffic. You come to a stop, want to pull away almost immediately, but just then it cuts out, and you have to wait up to a second before it's ready to go. That can be tricky if you are in the middle of a busy junction. This is one of the reasons why I chose a manual for my own car - at least you can control it at a brief stop by keeping the clutch down until you're ready to go.
G’day Nick, thank you very much for another very informative video, my Benz definitely has the start stop function and I never use it, I turn it off every single time I start my engine
Every car I've had with stop start never works in the winter because of short return journeys to work and back. The management system has to meet several criteria before even thinking about doing its thing. Only a journey of about 20 miles sorts it out. My app says my car is partially charged at the moment but I know not to panic and will be fine in the morning.
In the two years I've owned a 2018 GLC it's only worked a couple of time's, a recent drive from Cornwall to Edinburgh made no difference. Although a warning message advising to take a break popped up
Thanks Nick. My recently purchased A Class Diesel had been doing this I but noticed it needed to warm up a bit before Start/Stop functions - so you confirmed this is normal👍. Still working out how the lane assist works though as I don’t feel any difference even if I go over a white line? It is activated and symbol can be either white or green?
No worries! Ah I’ve covered that on my lane assist video: www.youtube.com/@npoleary/search?query=lane It’ll only work in certain situations and line types (and usually a couple of settings to tweak if you wanted to as well)
My two year old car had battery replaced under warranty as start/stop wasn't kicking in. Worked fine ever since but i disable it pretty much every journey as its just unnecessary wear and tear.
Starter motors these days and including mild hybrid systems are physically designed to do this. If this tech was on cars 20 years ago then yes Start/Stop would cause a lot of wear and tear. But the components used today are designed to actually do it. The average car years ago without this tech would have a starter motor rated for 50,000 engines starts before the starter motor might start to wear and / or need maintenance / replacing. Now they’re rated for in excess of 500,000 because they start / stop more.
Great video as usual, thanks Nick. I had the battery swapped (the dealer said there’s a separate battery for the start stop function on my W213) a while ago but this function still doesn’t activate very often. I didn’t realise it won’t activate on a slope so maybe that’s it. Thanks again.
Great video as always. Think mines just knackered. Not working at any temp (although not tried turning off AC). It might do it if I stop to fill up then does it after that.
That's super useful, thank you! 🎉 I sometimes wonder how it works with the "Extended automatic restart in traffic jams" option. I've impression that both cancel each other out 😂 It's probably not true but I couldn't wrap my head around that restart option yet, it also seems not to work when I'd expect it to.
Oh yeah I think I remember that when testing it before, the engine comes on automatically when the car in front moves. It was a while ago since I last used it though!
Thanks Nick, very informative as always. Whilst generally useful, the cut-out can be irritating in stop/start traffic. Can the default be changed so the stop/start is not automatically active?
Hi nick I am having the Ohme Home pro charger installed very soon myself and making an EV purchase, when are you doing the next review on the Ohme charger with regards of how to use it etc, keep up the good work on the channel 👏👏💪
Oh I will be soon! Just need another EV on test! I’ve had one on review and used it to charge and it’s been great! Think I’m getting the hang of the settings. Just wanted to test it again one last time. At the moment, I plug in, I receive a message to approve the charge (that’s the way I’ve got it set up to stop just anyone using it). And then it charges automatically at night on my off peak tariff. It’s awesome! £5 to charge a car up fully! That’s mad! Honestly wish I bought an EV last year 😅
Yup - low main battery will do it! Even with the car sitting on the driveway for a couple of days in a C Class is enough to lower the battery to below 75% which kills the Stop/Start. And don't expect it to re- charge sufficiently driving around town either! A 100 mile drive the other day did and so did the trickle charge that I often use to keep the battery conditioned.
I'm horrified to find that my 12V battery will run down after a few days of not driving. I've now been provided with a trickle charge - the same as I use for my lawn tractor. Should we really be pleased with new technology when we're being taken backwards in time by about 50 years ago when my dad used to keep his Morris Minor on trickle charge????
@@andyb8668 Fact of life I'm afraid with modern electronics. I had same problem with my 2018 C Class. I have improved the situation somewhat by investing in a RFID Key Box that I now put the key in by the front door when I come in. The spare key is also in an RFID Pouch. Apparently one of the reasons the battery drains is that the remote lock/unlock function continues to try to communicate with the key even with the ignition switched off.
Hey @andyb8668, it should last longer than a few days! That sounds like something’s not right for a healthy battery, I’d suggest chatting to a garage or mechanic to get it checked out.
Thanks@@npoleary , it was going to partially charged after 2-3 days, then low charge after another 2-3 days. Leaving it for much more than 1 week was going to critical. But it's back with the dealer now, so fingers crossed!
I always turn it off when I remember to do that. Even though this feature can reduce fuel consumption a bit, it does wear out the engine and starter motor faster over time. For longevity's sake it's best to keep it turned off.
But car manufacturers don’t fit the same starter motors. For example my car doesn’t even have a starter motor, it’s a starter generative similar to what’s in a plug-in hybrid. They’re designed to physically turn on and off more times than a normal starter motor.
I THINK YOUR VIDEOS ARE GREAT,I MEAN FROM THE FILMING PERSPECTIVE TO EDIT AND SCRIPT. GREAT JOB KEEP IT UP. IM STARTING A CAREER IN MERCEDES AND I WANT TO ASK YOU, WHERE DO YOU GET ALL YOUR RESEARCH? YOU SEEM TO KNOW SO MUCH. HOW CAN I BE KNOWLEDGEABLE LIKE YOU?
Awh thank you! Glad you enjoy them! To be honest it’s all self taught! 😅 although I do get a lot of my info from online. In a car I press buttons and see what happens! 😂
Hey Nick, great vid mate!!! I got a question for the a-class - how on earth do you gain access to the fusebox under the passenger feet? folding the carpet over doesn't provide enough space to completely access it properly
@@npoleary Nick you should :) can you ask one of the service guys at the dealership, I can easily fold it over, the door seal prevents it from folding all the way down for easy access to the fusebox, and pulling hard on it feels like I'll snap the door seal off it's fasteners breaking it
@@npoleary Nick I bit the bullet, I folded over as per the owners manual, but then needed to encourage the carpet towards and over the side of the door seal. Didn't need much to get carpet out behind the door seal. door seal does not need to come off - many in the forums go removing the door seal off first which is wrong
I’m not sure they’d appreciate me doing that! 😅 I’m very thankful they allow me to film there on new models and things. Taking apart their cars is probably not something I should be doing! Why are you trying to get in there anyway? Just curious?
Yeah it does save fuel (if start / stopped a lot) and of course emissions but it does check the make sure that it can and will start again. Of course the A/C doesn’t run when the car’s engine is off so when it’s hot summer weather you can just disable it 😛
I suspect the battery on my 2018 petrol Honda Jazz isn't quite up to it because stop star rarely kicks in even after a long drive. It displays why: temperature, battery and AC but the latter is very confusing because is shows even when AC has been turned off!
On my 2017 Subaru, my battery was 6 years old, once it stopped and then did a long beep with a warning I never seen before and I pressed the start button to start the car. My assessment was the battery didn’t have the voltage to restart the car after it had turned itself off. I then replaced the battery and had no problems since. Normally I disable this feature as I don’t like the engine shutting off at roundabouts.
Another great video! I’ve only had my 2024 GLA for a couple weeks and the on/off did something odd today. It didn’t seem to be working … then out of nowhere there was a loud beep and the green A blinked … but at the top of the display … rather than in the usual bottom location. Any idea what that means or why it would happen?
Thank you! No I’ve not seen that happen in a car before. Only thing I can suggest is keep an eye on it or take it to a dealer or mechanic and they’ll be able to take a look 👍🏼
soooo informative! Love it. Can you please explain the climate control point you made please is it to with the dynamic select where you can pic comfort or eco
Thank you! So the climate control bit, if it’s really cold outside for example and you set 28°C and inside the car is really cold, the car might not do the start / stop until it’s got the temp near where you want it. It’ll prioritise getting you warm first. That and the starter battery will not perform as well in the winter so it’ll need charging up for longer too as you drive round. Same goes for demisting windows, if you put the de-mister on, it’ll prioritise that over anything else.
Fuel economy would be greatly increased if the people who program stoplights coordinated them with the speed limit, so that you could drive from green to green to green to green to green The most fuel is used going from a standing start to whatever the speed limit is. One stoplight controller told me that one street in the city had been deliberately programmed so that you drove from red to red to red to red to red, because they wanted to discourage traffic on that street! Stop/start on cars is kind of like CA mandating how many loads of laundry you can do, while at the same time refusing to build new reservoirs to store excess rainwater that the state instead dumps into the ocean by the billions of gallons.
Scotty Kilmer who is in the States suggests you deactivate it every time you start the car. In your tests did you actually, every time you stopped apply the handbrake and put it in neutral or as an element of people do, ride the clutch?
I asked ford to turn it off. They said no. I found some software to go into settings and turned it off permanently. It may save you pennies using stop start. But in the long run it will cost you a lot in repairs. Starter. Starter ring. Battery. All take a hammering.
Thanks Nick. Very helpful and now I can understand why it doesn't always turn off. I do however ask if you know why I occasionally see a turquoise coloured symbol and not just the green for on and yellow for off?
I have been told that the start/stop will not work when the check engine light is on. Also, I thought it is the catalytic converter temperature that prevents it from working rather than how fast or distance driven when you set off. I could be wrong. :)
Thanks for the great video. Very useful. If I may ask, how long will the start stop last when it is activated? Mine only last less than 30s. If that normal?
I guess it depends on the car (how much power you’re using / climate control). I’ve been in cars when it’s last 20 seconds but also 2 minutes before. Depends on the battery health too!
start stop won't work in sports mode sports plus or race depending on your model and the humidity/temp sensor is usually mounted next to the rain señor Ect behind the panel at the rear view mirror so takes along time to warm up Ect if car is cold again stopping the stop start function
I bought a new 2024 GLC 300 COUPE and between 48 to 52 it makes a high pitch loud enough where you can hear it with the music on and the dealership claims that the cabin is so quiet that you can hear the transmission
Start stop is a pain in the ass, I switch it off all the time. I have even asked Mercedes if there is a permanent software fix. It is pointless and saves fcuk all and is just bloody annoying.
I had a Renault Capture whose Start/Stop stopped working one day. It didn't work for close to a month and then one day the car just didn't start. The battery died. Never had it happen in my Mercedes as of now but if it happens then I'll immediatly check the battery first.
Mercedes are quite clever, as long as you have the car linked to your Mercedes me account (if it’s 2015 ish or newer) it’ll email you if the battery is low. And also it’ll tell you on the screen again roughly 2015 ish or newer 👍🏼
what fuel is saved is lost when the battery fails. I had a 220E estate and the S/S battery failed and the car went into limp mode as I was pulling onto a roundabout in peak traffice on A1. I was lucky not to get nailed by a huge truck. My experience tells me he stop/start idea is ok in theory and legistaltion but as a safety risk it is the devil and unnecessary.
Well I guess it depends on how old the battery is, like all batteries they have a finite life span so replacements can be needed from time to time. Although I have seen the message appear on cars when the battery is low so hopefully they’ll be a bit of a warning in advance!
Hi Nick. I have same car as you about 4 months old. This week my car kept sending me mails stating it was closing the car windows due to rain, every 20 secs or so. Went out and car completely dead. I put on my ctek5 for a whole day and nothing. Mercedes sent out RAC and they told me a Ctek will not charge a dead battery only keep it topped up. They connected theirs and away it went. They told me because I was retired and just did shopping trips the front battery could not cope. The front battery is only for the mbux system on the dash, everything else is from the rear battery which disconnects when front battery dies. Because of my lifestyle they told me to connect my Ctek when it’s in the garage. Did that and it’s ok now.
Ah okay, yes I mean it does depend on what mileage you do / how often the car is on. If it’s only very short trips then a trickle charger might be a good investment!
Hey Nick - Great vid! Side note though, i have a 1.3L A200 Premium Sport A Class 2019, a full tank usually costs £55-70+-, It says on the info screen that i get only max 198-200mil range? Surely i can get more range? I've seen other A Classes with same spec and engine go above 200 and 250mil? Thoughts?
Hey CertifiedMrTech, Thank you! Yes I know the stat you mean. Honestly best thing, stop looking at it 😅 let me explain…I promise it’ll make sense! Basically pretty much all cars have a trip computer and usually include a range indicator like on your car (same as mine). It’s really useful however on some occasions you can look down and it’ll say 200 miles and then others 400 miles. The most I’ve seen is 420 ish I think. As GoProflying mentioned it can be down to driving style but the most probable factor is where you’re driving. If you’re never getting above the speed of 40mph, you’ll never get more miles per tank of fuel. This is because most speeds under 40mph will encounter traffic in built up areas with lots of start / stops. If you go on a long trip somewhere, watch what happens when fuel up, that mileage will shoot up. But then when you return to doing lots of smaller trips round town, it’ll very quickly go back down again. It’s just the computer adjusting to where you’ve driven etc so although useful, not always accurate as it doesn’t know what trip you’re going to do next! Range computers will show you usually the last hundred or so miles of your driving etc Hope that makes sense, message me back if you’re still not sure 🙏
If you have not already covered this topic, I would like to know more about where the MBUX system is manufactured, where the chips are from, its reliability, and the costs associated with fixing it, should it malfunction. I'd also like to know what the most likely failure is, and the effects of that. Years ago, engines reliability was the big thing, Today it seems that infotainment system reliability is the thing to look for.
Replied to your other message 🤓 Hey davesmith5656, Yeah cars are these days! They have such sophisticated systems! 🤓 Really sorry I don’t know that, out all of the car manufacturers I review and produce content on I don’t think any of them explain that. I would imagine they do most of the work in house, but of course some components are probably sourced elsewhere. For MBUX specifically I ran a quick internet search and found this if that helps? www.luxoft.com/pr/luxoft-and-daimler-codevelop-technology-platform-that-powers-the-mbux-infotainment-system I know they also use NVIDIA for their graphic chipsets too which is pretty cool! In terms of costings, I wouldn’t know you’ll have to ask Mercedes. I do own one but it’s under warranty so if anything did happen it would be covered 👍🏼
@@npoleary---- Thanks. I've watched many videos and I've read many reviews, and all of them, if they bother to get beyond a showroom description, are about engines. The infotainment discussions are limited to features, with maybe only one or two passing mentions of reliability. You have to go to the comments to get any additional info (like how upset people are with them). The manuals for the different years are combined even though the features and functions are different, so even there it's not so easy to figure out what's in the car package. Computers on wheels. Do you happen to know, if you have an electronic shift, if the MBUX, goes down, can you get the car into neutral to have it loaded onto a tow truck? Quality and consistency of dealership service is also a huge issue. If the car is under warranty they probably do a good job and don't "leave something on the table". If it's out of warranty, which shop you take it to is a major decision. I've learned not to trust dealerships, and to choose shops carefully. E.g. take it for an oil change, and a month later the oil pump breaks, get that fixed, and a month later the alternator dies, get that fixed, and a month later a fuel pump malfunctions, etc.. They know what they're doing. I'm thinking about a car kit. No computers, and I know how to fix it myself. Keeping a 60 year old classic is a lot of work.
Well the thing is with reviews in general especially when creating content, most reviewers or content creators or RUclipsrs will only have a short time with a brand new model. I can vouch for this, the shortest amount of time I’ve had with a new car is an hour 🤯 not good! The longest is a week. Unless one was bought, comments couldn’t really be made about reliability long term because of the short time with the cars. I have however bought a Mercedes A 180 last year so I could talk about that but everything’s all good at the moment, and as it should be! It’s brand new and a premium German car. No manufacture is perfect though which is why last year I chose to diversify and cover more brands than I did before to help people make the right choice 👍🏼
@@npoleary ---- When I go to a car review video, I'm looking for (hoping for) more than a walk-around. I never really thought about doing uploads, or how to get permissions or whatever to review various cars, but I do appreciate that the industry is huge, and doing an in-depth on some new model would require a pretty extensive knowledge base to offer relevant comments and comparisons. It's the same sort of thing with surfing videos: they should explain the sea bed formations that produce the waves, and should show some footage of the waves from a distance - but do not. Mostly, you get very good to excellent shots of rides. There, it's very simple, compared to cars, and surfers probably know very well what's beneath them, but still, at best just passing mention of the sea bed under the waves. Your "tips and tricks" are useful! Vids talking about the beauty of grills and stitching and styling are not useful (I can see all that for myself). I do try to empathize with mechanics (technicians) - it's beyond me how they keep up, and it's the same with doctors, having to keep up with new journal articles and new procedures. There may be some summary database on car computer systems and reliability, and some data on whether or not there is partial failure or only comprehensive failure.
I forgot I had start/stop technology as I don’t do a lot of mileage in my GLA but had a long run the other day and it started working every time I stopped. I also notice if I go on holiday I get notifications is the app that my battery is low and needs charging. I’m planning to put the battery charger on a trickle charge the next time I leave it for a while. Ever had this issue with any car I’ve had in the past including Audi’s and BMW’s
Ah yes! A good run would charge it up Well it depends of course how new / how old the car is. Starter batteries can last up to 5 years and even longer these days but luckily when cars are sold from main dealerships, they will usually check the battery health and replace if it’s not at optimum performance for peace of mind. Newer cars draw more power than ever before with all of the tech in them! 🤓
Hi Nick I took delivery of a 2021 GLA250e and drove it over the weekend but noticed it didn’t seem to have start stop on there. Is this right or am I not doing something correctly. Any advise would be welcome. Thank you
Ah nice! I’m a bit confused by what you mean though… A plug-in hybrid is a hybrid, it doesn’t have start / stop technology (as such) because it has an electric motor and separately an engine. So you’ll be driving on electric most of the time but if the electric is low for whatever reason then the engine will come on.
You missed one. I'm new to this tech (my previous car is 20 years old) - and the second time I drove my new car the start/stop didn't work ... because I had accidently turned it off on the switch under the start button.
Oh no that’s not good, sadly as with all cars an engine management light could mean all sorts of things. I wish their screens actually said what was wrong but annoyingly needs diagnostic equipment. Pop it to a car garage / mechanic and they’ll be able to take a look and find out what’s going on 🙏
it seems like my cornering lights are not working on v-class mp 300d 4matic airmatic. can i turn them on? know that i have to turn the steering wheel 40km drive and so on. is there anything i can do myself?
Not tested them myself before but I did observe them coming on when the steering reached a certain angle. Although I’m not sure if it’s any different on the V-Class. What light system do you have? It’ll usually say on the exterior light housing somewhere. LED High Performance Lights MULTIBEAM LED etc
Start stop on my 981 not worked for about four years all of sudden recently decided to work just one time Battery AGM will be ten years old this year. I’m expecting it to give up soon but until then it doesn’t matter as the stop start doesn’t bother me. Waste of energy you have to have a special and larger capacity battery costs third more than a standard and also more wear on electrical components I do have the option to switch it off when using vehicle. If you are stationary a long time I switch all off anyway I cannot see how it saves pollution as when you restart engine it technically wastes fuel on startup on any engine.
How do you turn the bloody start stop off, I will hate it when I soon get my 2020 GLC 300. Will save buggar all fuel and more wear and tear on the car.
You’ll save fuel when the engine is off. So the more you spend in traffic the more fuel you’ll save with a system like this. Start / Stop motors have been designed with start / stop in mind. It’s physically designed and rated to cope with more start / stops. If it used the same tech as years ago, then yes that would be bad. But if you want to turn it off per driving session, underneath the start / stop engine button then’s an “A” to toggle it off. Useful a quicker getaways pulling out from a roundabout or to keep the A/C on 👍🏼
HI Nick, do you have any idea about my C350e which the e-mode has not worked recently? There is no warning light, and the engine keeps going even when I'm waiting for the red light. The temperature outside is around 15 degrees. I'm so confused-
Oh really? That doesn’t sound quite right It’s been a few years since I drove one but I’m pretty sure that was the All-Electric mode. Have you spoken to a garage or dealership? I’m sure they’ll be able to check it out.
Does that function mess up car battery? Whenever I turn on my Mercedes c300, it is automatically activated. I have been having problems with my car when I come to stop and hit the gas paddle to start my car moving again and sometimes it doesn’t start moving and the gas paddle doesn’t seem to function. I already had my battery replace and still having same problem.
Start / Stop won’t mess the battery up, they’re physically designed to handle more start / stops. The only difference is that they cost a bit more due to their battery density. However what you’re describing doesn’t sound right so I’d suggest getting Mercedes or a mechanic to look at it and find out what’s going on.
the temperature of your coolant does not indicate whether the engine is warm this is a misconception the temperature of the coolant is in the middle within 5 minutes but the engine oil takes much longer to warm up so the coolant temperature does not indicate the engine temperature
True but sadly not many people have access to the exact oil temp on their car, mine certainly doesn’t! However…I have driven a couple of cars before that do have it!
Auxiliary battery is the start / stop system 🤓 Unless it’s a battery for something else, a campervan for example may have an auxiliary battery but that’ll power the fridge / freezer / lights etc
@@gavinspringett To my understanding (I am not a technician), the auxiliary battery is a second (smaller) battery, mainly supporting the electronics in the car. Depending on the model, it might be located under the glove compartment or the boot, e.t.a. The main battery (under the hood) supplies power to the started motor and other power intensive equipment, not the auxiliary battery.
Hi Nick, I own a Mercedes C200 from 2016. When I first had it I was able to go into the computer thingy and turn off the default for the stop/start but ever since having the battery replaced this no longer works. It appears as though it's off on the display but the only way I can turn it off is pressing the green button on the centre console each time I go out in it. Have you any ideas what's going on and how I can turn it off by default again? Mark.
Hey Mark, ah nice! Well the start / stop or stop / start tech is always controlled using a button (usually with green icon). This is how you turn it on/off per driving session. Same for all cars, don’t think I’ve seen one any different
Have always seen it as yellow in my car and never green. Could this be an issue with battery? I have had long journeys in summer and winter but never seen it other than yellow.
I had a C Class 250 coupe and had an issue with engine warning light. Diagnostics revealed a failed NOX Sensor. Replaced a few times but Start/Stop tech failed repeatedly. Never got to the bottom of the issue.
@@npoleary Yes, It went back every time and they fitted a new NOX sensor. The Start/Stop operated for a short time and then spuriously. All this was done under warranty but it was annoying. Change car last year for a GLC 300 Coupe. Love it! No issues.
No sadly not, it’s emissions requirements that manufacturers have to have it auto enable on an engine start but it can be switched off per session if needed.
I have a Renault Captur. It never works, always showing priority battery charging. It is so battery hungry even when sitting outside the house it can never recharge fully. I drive jt around sll day and it is still showing priority battery charging..
Isn't it Stop/Start rather than Start/Stop? 10 years? I had it on a VW Polo in 1984 so it has been around for 40 years! A few years ago my C class just never did it and about 6 months later I needed a new battery and then it worked so it is a good indicator that the battery is not at its best. I must say Mercedes have it just right as to when it cuts out in and re-starts. Wife's Peugeot has it, you stop and it cuts out, then passenger opens the door to get out and that starts the engine!
I would ask them to do a battery health check and see if there’s a battery drain. Although I should add I’m not a technician or anything like that so I’d ask them to take a closer look. Driving 40km a day should be plenty!
Really sorry if it’s not anything in the list in the video then it could be mechanical related so probably best to get a dealer or mechanic to check it out. If the battery is only a year old, can you speak to the person who changed it?
@@npoleary I did the battery cost me nearly £300 the garage wanted etc money to fit it. The battery reading over 13volts before starting it. So I’m not sure what’s up but when I scan my van it’s saying there’s a air temperature sensor needs changing quoting number p007d
Hmmm strange Really sorry I’ve not worked on cars from a mechanical point of view so wouldn’t know what to suggest apart from going to a mechanic. That’s what I would do anyway, either that or a dealer if it had a warranty etc.
@@npoleary it’s a lwb Vw crafter 2014. Pannel van that I’ve turned into a camper van. Own it since 2018 never had a problem with it till after Christmas it started playing up with other things too
Oh I see, really sorry I initially thought you meant A-Class (wasn’t sure what crafter meant) I’ve only ever been in passengers cars that Mercedes offer so never in their vans. I might look to cover them on the future though! I know the insides of them can be a little different from what I’ve heard.
It has never wworked in my 2019 Ceed Gt Line, always displaying the amber light no matter what time of year it is. Ive no plans to ever address this as it was something I absolutely hated in my previous car.
You mention that if you've used several start/stops in succession short time then it won't work until the battery has been charged yet we were led to understand that it was designed for being in queuing traffic to reduce emissions 🤷♂️
Yeah exactly 🤓 It’ll help with a few start stops (and I mean quite literally back to back) but if the voltage drops too low then it’ll stay on for a little while to charge back up. Quick succession I mean is literally one after the other, if it’s spread out over a few minutes or so then it’ll be able to do a few.
In the best cars if you Want your engine to `stop` in traffic you just turn a Key. You dont have the Worry of the Ambient temp, rate of speed/distance travelled, whether you`ve wet yourself or the battery doesn`t like the weather conditions?. Key! ,you don`t even have to look, it`s the Most Accessable thing in the effin Car!
Replaced my aux battery and now it says charging and that is for the last month it will not charge even though it says it is charging so Idk what is going on it is crazy gonna have to go to the steelership
Hmm yeah if none of the things in this video work and you’ve even changed a battery I’d suggest chatting with a mechanic or dealer. They’ll be able to sort it 🤓

I had a 1960 Morris Minor that used to stop at junctions. A pioneering form of that feature? No, it was just knackered!
How strange, I was looking at my start/stop this morning wondering why it wasn't working. Now I know, thank you.
Me too
Thanks so much . I just received my Mercedes. Didn’t know what the yellow circle ,with the A inside was. It was my battery. Had not been driven for about two weeks. Thanks again.
No worries! Glad you enjoyed the video! 🙏🙏
I had the battery in my GLC250 replaced under warranty to correct the failure of the start/stop function. Great to understand that there are other causes as well. Thanks Nick. Great video!
Thank you! Glad you enjoyed it! 🤓
Thanks for explaining the workings of the stop/start system Nick. Stay warm mate. Cheers Dennis
Thank you! Glad you enjoyed it! Thanks for watching!
Thanks for this great video. I am having trouble with my start/stop at the moment. It doesn't start to work until around 4pm even though it's on the road all day working. At least I can rule this list out when I see mercedes later on this month. Love your videos Nick. Keep it up 😁
Ah no worries! It’s bound to be one of those!
Great video again and a good explanation.I do a lot only driving in the city and its not working , but when i drive on the motorway it works direct , thx again 👍
Thank you! Glad you enjoyed it! 🤓🙏
Another good one Nick. I remember as an ax Fiat mechanic left hand Ritmo ES had stop start around 1982 really astonished me at the time they weren’t good starters in the first place😂
An economy model called the "ES" ("Energy Saving") was also available, it featured an early start-stop system. It featured some detail modifications to the aerodynamics, an optimised (higher compression ratio and different valve timing) version of the 1301 cc engine rated at 65 hp (48 kW), an engine shut off system (when idling) and electronic ignition.
Thank you! Ah interesting! 😊
Thanks
I tend to switch mine off if I remember.
It only works about 20% of the time, so I find it so unpredictable it’s actually annoying and unexpected when it does work.
I've had my merc for 6 months now, I think it has only worked 2 or 3 times during that time! Not that I am bothered as have always found the feature annoying in other cars.
Totally agree
I’m going from a 2007 Chrysler aspen to a 2022 GLC300 and this has been so helpful in making me feel prepared, BLESS YOU❤
Ah very nice! Glad you enjoyed the videos! 🤓
@@npoleary I did! The whole playlist was amazing, also idk why but your voice makes it even better JUST ALL AROUND A SOLID 10🙏🏻🙏🏻
Im now in said GLC300 and these have been SO helpful omg, there’s so many stuffy old guys putting these videos out and half of them seem like they don’t know what they’re talking about so I really appreciate the educated way you get information across while being easy to understand even for someone who’s never driven any car in their life lol. Keep on being awesome!💕
Awh thank you! 🙏
Well I’ve got a few Mercedes tutorials lined up soon! And I am thinking another tips and tricks video is overdue so I’ll see what I can do! 😛
As a reminder for folks who leave their cars sit for extended periods. Some MB models have a standby mode that will slow the battery(s) drain. Check your owner manual to see if your car supports this mode. This is really helpful if you don't have easy access to an outlet for a trickle charger to keep the battery topped up.
Start stop system is the most hated thing in modern car. All time when I remember I try to turn off this system. Start/stop system makes a negative impact on your engine and it’s annoying for a driver. Savings from fuel are minimal but cost of repairs engine after few years can be huge.
I beg to differ. Stop start systems are designed to do so and and there are no reports of repairs caused by it. If you know of any, I’d be very thankful if you could point me to them.
Stop start systems usually have a starter-generator instead of separate starters motors and alternators.
The savings are very real. My car counts the time the engine is turned off from the time it got last fuelled. It adds up to about 1.5 hours per fill tank!
That’s much more than I’d ever imagined.
@@Conservator. The engine is most destructive when starting. When driving in a crowded city with the existing Start-Stop system, the engine starts up to 20-30 times during the driving sequence. It will also be destructive to the turbocharger, battery or starter …
Well my car is now 13 years old and I just replaced the battery for the first time. I don’t have any problem with the stop/start.
@@LukaszOlszewski
An engine has the most wear when cold started because most of the oil will have dripped down.
The stop/start system will only kick in when the engine is warm. The duration of the stops is too small for oil deprivation to occur.
The engine is stopped just before ignition and it will hardly take any effort by the starter/generator to get the engine going again.
Do you have reports of excessive wear and tear from stop/start systems?
2015 ford focus, stop,start not worked for a while. Brand new correct battery now on and still doesn't work? Any ideas???
Brilliant summary as usual Nick.
Thank you! 🙏
Great content and professional. I used this video as a checklist list to make sure I wasn't missing anything as my start/ stop is annoyingly temperamental. 9 times out of 10, it doesn't work. I've had the battery tested, and apparently, it's ok.
Glad you enjoyed the video! 🙏
Thank you very much Nick. I'll get my A180D booked in at the garage.
These are the kind of videos I love when you post
Haha thank you! 🙏
😊
I generally deactivate the feature when I start the car. On my model, the re-start can be quite jarring.
Yep, always turn mine off.
I can save fuel and emissions but of course depends on when it was made. My first car with start / stop years ago took like a whole 2 seconds to start but cars these days start very fast!
I just coded it to remember the start stop button. Its so much better for the Engine to Turn it Off.
Nice one Nick! Mine doesn’t work but I find this a blessing. I put mine down to having a tracker and two dashcams front and rear. I get the Mercedes me app complain about once a month that the battery is critical. Which means my start stop pretty much stays off all the time.
Oh I see yeah extra accessories and resources might affect it.
Better to be safe than sorry though when it comes to dashcams and trackers!
Interesting, find my stop start prioritising start stop over heating and air con.
Also works better in winter when there is a lot of load.
In the case of the Mercedes you still have the situation of stopping at a stop sign and the camera being able to read the sign, it also does not activate the start/stop
I've always found autos with stop/start are irritating to drive in traffic. You come to a stop, want to pull away almost immediately, but just then it cuts out, and you have to wait up to a second before it's ready to go. That can be tricky if you are in the middle of a busy junction. This is one of the reasons why I chose a manual for my own car - at least you can control it at a brief stop by keeping the clutch down until you're ready to go.
I just noticed this last night, I was in stop and go traffic plus it was pretty cold. It didn't bother me much however.
G’day Nick, thank you very much for another very informative video, my Benz definitely has the start stop function and I never use it, I turn it off every single time I start my engine
Thank you! Glad you enjoyed it! 🙏
I've been wondering why mine hasn't been working. Thanks for sharing.
No worries! 🤓🙏
I found that s/s stops if heater controls is set to one of the screen settings, change it to blow internally and s/s works again.
I didn’t think mine worked at all, but now I know what to look for and in what conditions it will/will not engage. Very good video, thanks!
Thank you! 🙏
Helpful.
Battery level is probably the most common
Could be! Sadly there’s not a way of checking (easily) on most cars
Every car I've had with stop start never works in the winter because of short return journeys to work and back. The management system has to meet several criteria before even thinking about doing its thing. Only a journey of about 20 miles sorts it out. My app says my car is partially charged at the moment but I know not to panic and will be fine in the morning.
In the two years I've owned a 2018 GLC it's only worked a couple of time's, a recent drive from Cornwall to Edinburgh made no difference. Although a warning message advising to take a break popped up
Hmmm might be worth chatting with a garage or a Mercedes dealer and they can check it out for you!
Thanks Nick. My recently purchased A Class Diesel had been doing this I but noticed it needed to warm up a bit before Start/Stop functions - so you confirmed this is normal👍. Still working out how the lane assist works though as I don’t feel any difference even if I go over a white line? It is activated and symbol can be either white or green?
No worries! Ah I’ve covered that on my lane assist video: www.youtube.com/@npoleary/search?query=lane
It’ll only work in certain situations and line types (and usually a couple of settings to tweak if you wanted to as well)
My two year old car had battery replaced under warranty as start/stop wasn't kicking in. Worked fine ever since but i disable it pretty much every journey as its just unnecessary wear and tear.
Starter motors these days and including mild hybrid systems are physically designed to do this.
If this tech was on cars 20 years ago then yes Start/Stop would cause a lot of wear and tear.
But the components used today are designed to actually do it.
The average car years ago without this tech would have a starter motor rated for 50,000 engines starts before the starter motor might start to wear and / or need maintenance / replacing.
Now they’re rated for in excess of 500,000 because they start / stop more.
Great video as usual, thanks Nick. I had the battery swapped (the dealer said there’s a separate battery for the start stop function on my W213) a while ago but this function still doesn’t activate very often. I didn’t realise it won’t activate on a slope so maybe that’s it. Thanks again.
Thank you! (Depends on the car with the slope thing) but yes there are quite a few reasons as to why! 🤓
Great video as always. Think mines just knackered. Not working at any temp (although not tried turning off AC). It might do it if I stop to fill up then does it after that.
Thanks for watching! Yeah if it’s not working then get in touch with a dealer or mechanic etc I’m sure they can check it out (if you want to that is)
That's super useful, thank you! 🎉 I sometimes wonder how it works with the "Extended automatic restart in traffic jams" option. I've impression that both cancel each other out 😂 It's probably not true but I couldn't wrap my head around that restart option yet, it also seems not to work when I'd expect it to.
Oh yeah I think I remember that when testing it before, the engine comes on automatically when the car in front moves.
It was a while ago since I last used it though!
I was driving last week on reserve (less than 50km) and stop start was working on my W177, I was surprised 😊
Think it varies from car to car but some might might still. Guess it depends how much fuel pressure the fuel lines have
Thanks Nick, very informative as always. Whilst generally useful, the cut-out can be irritating in stop/start traffic. Can the default be changed so the stop/start is not automatically active?
No sadly not, it’s something that’s enabled by default on all cars over the past 10 years or so
@@npoleary Thank you, Nick
No worries! 🤓
Hi nick I am having the Ohme
Home pro charger installed very soon myself and making an EV purchase, when are you doing the next review on the Ohme charger with regards of how to use it etc, keep up the good work on the channel 👏👏💪
Oh I will be soon! Just need another EV on test!
I’ve had one on review and used it to charge and it’s been great! Think I’m getting the hang of the settings. Just wanted to test it again one last time.
At the moment, I plug in, I receive a message to approve the charge (that’s the way I’ve got it set up to stop just anyone using it). And then it charges automatically at night on my off peak tariff. It’s awesome! £5 to charge a car up fully! That’s mad!
Honestly wish I bought an EV last year 😅
Yup - low main battery will do it! Even with the car sitting on the driveway for a couple of days in a C Class is enough to lower the battery to below 75% which kills the Stop/Start. And don't expect it to re- charge sufficiently driving around town either! A 100 mile drive the other day did and so did the trickle charge that I often use to keep the battery conditioned.
I'm horrified to find that my 12V battery will run down after a few days of not driving. I've now been provided with a trickle charge - the same as I use for my lawn tractor. Should we really be pleased with new technology when we're being taken backwards in time by about 50 years ago when my dad used to keep his Morris Minor on trickle charge????
@@andyb8668 Fact of life I'm afraid with modern electronics. I had same problem with my 2018 C Class. I have improved the situation somewhat by investing in a RFID Key Box that I now put the key in by the front door when I come in. The spare key is also in an RFID Pouch. Apparently one of the reasons the battery drains is that the remote lock/unlock function continues to try to communicate with the key even with the ignition switched off.
Hey @andyb8668, it should last longer than a few days! That sounds like something’s not right for a healthy battery, I’d suggest chatting to a garage or mechanic to get it checked out.
Thanks@@npoleary , it was going to partially charged after 2-3 days, then low charge after another 2-3 days. Leaving it for much more than 1 week was going to critical. But it's back with the dealer now, so fingers crossed!
I always turn it off when I remember to do that. Even though this feature can reduce fuel consumption a bit, it does wear out the engine and starter motor faster over time. For longevity's sake it's best to keep it turned off.
But car manufacturers don’t fit the same starter motors. For example my car doesn’t even have a starter motor, it’s a starter generative similar to what’s in a plug-in hybrid.
They’re designed to physically turn on and off more times than a normal starter motor.
I THINK YOUR VIDEOS ARE GREAT,I MEAN FROM THE FILMING PERSPECTIVE TO EDIT AND SCRIPT. GREAT JOB KEEP IT UP. IM STARTING A CAREER IN MERCEDES AND I WANT TO ASK YOU, WHERE DO YOU GET ALL YOUR RESEARCH? YOU SEEM TO KNOW SO MUCH. HOW CAN I BE KNOWLEDGEABLE LIKE YOU?
Awh thank you! Glad you enjoy them!
To be honest it’s all self taught! 😅 although I do get a lot of my info from online.
In a car I press buttons and see what happens! 😂
@@npoleary that's awesome! Thank you for sharing with me! i wish you the best and will be watching your videos :)
Hey Nick, great vid mate!!! I got a question for the a-class - how on earth do you gain access to the fusebox under the passenger feet? folding the carpet over doesn't provide enough space to completely access it properly
Thank you! Glad you enjoyed it! Oh I’ve never gone in there before, sorry!
@@npoleary Nick you should :) can you ask one of the service guys at the dealership, I can easily fold it over, the door seal prevents it from folding all the way down for easy access to the fusebox, and pulling hard on it feels like I'll snap the door seal off it's fasteners breaking it
@@npoleary Nick I bit the bullet, I folded over as per the owners manual, but then needed to encourage the carpet towards and over the side of the door seal. Didn't need much to get carpet out behind the door seal. door seal does not need to come off - many in the forums go removing the door seal off first which is wrong
I’m not sure they’d appreciate me doing that! 😅
I’m very thankful they allow me to film there on new models and things. Taking apart their cars is probably not something I should be doing!
Why are you trying to get in there anyway? Just curious?
@@npoleary dashcam install :) I've figured it out sand totally understand not being able to do that on their new cars.
Wow…..personally I shut it off, but I never knew all the parameters that influence start/stop!
Yeah it does save fuel (if start / stopped a lot) and of course emissions but it does check the make sure that it can and will start again.
Of course the A/C doesn’t run when the car’s engine is off so when it’s hot summer weather you can just disable it 😛
I suspect the battery on my 2018 petrol Honda Jazz isn't quite up to it because stop star rarely kicks in even after a long drive. It displays why: temperature, battery and AC but the latter is very confusing because is shows even when AC has been turned off!
Can’t ever get mine to work on my 2019 Jazz. Even had a new battery fitted with no joy.
@@robparker1625 that's why my battery is staying put until it conks out.
On my 2017 Subaru, my battery was 6 years old, once it stopped and then did a long beep with a warning I never seen before and I pressed the start button to start the car.
My assessment was the battery didn’t have the voltage to restart the car after it had turned itself off.
I then replaced the battery and had no problems since.
Normally I disable this feature as I don’t like the engine shutting off at roundabouts.
Ah interesting, thanks for sharing! Glad you got it sorted though!
Another great video! I’ve only had my 2024 GLA for a couple weeks and the on/off did something odd today. It didn’t seem to be working … then out of nowhere there was a loud beep and the green A blinked … but at the top of the display … rather than in the usual bottom location. Any idea what that means or why it would happen?
Thank you! No I’ve not seen that happen in a car before. Only thing I can suggest is keep an eye on it or take it to a dealer or mechanic and they’ll be able to take a look 👍🏼
soooo informative! Love it. Can you please explain the climate control point you made please is it to with the dynamic select where you can pic comfort or eco
Thank you!
So the climate control bit, if it’s really cold outside for example and you set 28°C and inside the car is really cold, the car might not do the start / stop until it’s got the temp near where you want it. It’ll prioritise getting you warm first. That and the starter battery will not perform as well in the winter so it’ll need charging up for longer too as you drive round.
Same goes for demisting windows, if you put the de-mister on, it’ll prioritise that over anything else.
Fuel economy would be greatly increased if the people who program stoplights coordinated them with the speed limit, so that you could drive from green to green to green to green to green The most fuel is used going from a standing start to whatever the speed limit is. One stoplight controller told me that one street in the city had been deliberately programmed so that you drove from red to red to red to red to red, because they wanted to discourage traffic on that street! Stop/start on cars is kind of like CA mandating how many loads of laundry you can do, while at the same time refusing to build new reservoirs to store excess rainwater that the state instead dumps into the ocean by the billions of gallons.
Scotty Kilmer who is in the States suggests you deactivate it every time you start the car. In your tests did you actually, every time you stopped apply the handbrake and put it in neutral or as an element of people do, ride the clutch?
My E400 A/T hardly ever start-stops and is seemingly random. It’s had a new battery from the dealer to try to help but it hasn’t made much difference.
I asked ford to turn it off. They said no. I found some software to go into settings and turned it off permanently. It may save you pennies using stop start. But in the long run it will cost you a lot in repairs. Starter. Starter ring. Battery. All take a hammering.
Thanks Nick. Very helpful and now I can understand why it doesn't always turn off. I do however ask if you know why I occasionally see a turquoise coloured symbol and not just the green for on and yellow for off?
No worries!
Ah that means it’s switched the engine off 🤓
If you like Start / Stop as a feature get a hybrid
I have been told that the start/stop will not work when the check engine light is on.
Also, I thought it is the catalytic converter temperature that prevents it from working rather than how fast or distance driven when you set off. I could be wrong. :)
Oh yeah if there’s something not right with the engine then it wouldn’t do it for sure. That could be a part in it to possibly!
Thanks for the great video. Very useful. If I may ask, how long will the start stop last when it is activated? Mine only last less than 30s. If that normal?
I guess it depends on the car (how much power you’re using / climate control).
I’ve been in cars when it’s last 20 seconds but also 2 minutes before. Depends on the battery health too!
@@npoleary I see. Thank you so much for sharing your experience. 😊
I wish it didn't work at all on my car.
start stop won't work in sports mode sports plus or race depending on your model and the humidity/temp sensor is usually mounted next to the rain señor Ect behind the panel at the rear view mirror so takes along time to warm up Ect if car is cold again stopping the stop start function
Very true! 🤓
I bought a new 2024 GLC 300 COUPE and between 48 to 52 it makes a high pitch loud enough where you can hear it with the music on and the dealership claims that the cabin is so quiet that you can hear the transmission
Oh really? Interesting! 🤓
Start stop is a pain in the ass, I switch it off all the time. I have even asked Mercedes if there is a permanent software fix. It is pointless and saves fcuk all and is just bloody annoying.
4 times with Mercedes, never sorted it out….last visit over a year ago….it only worked twice in the past year! Given up.
I had a Renault Capture whose Start/Stop stopped working one day. It didn't work for close to a month and then one day the car just didn't start. The battery died.
Never had it happen in my Mercedes as of now but if it happens then I'll immediatly check the battery first.
Mercedes are quite clever, as long as you have the car linked to your Mercedes me account (if it’s 2015 ish or newer) it’ll email you if the battery is low. And also it’ll tell you on the screen again roughly 2015 ish or newer 👍🏼
It's better for your engine if start/stop isn't working so be happy when you see this warning light
what fuel is saved is lost when the battery fails. I had a 220E estate and the S/S battery failed and the car went into limp mode as I was pulling onto a roundabout in peak traffice on A1. I was lucky not to get nailed by a huge truck. My experience tells me he stop/start idea is ok in theory and legistaltion but as a safety risk it is the devil and unnecessary.
Well I guess it depends on how old the battery is, like all batteries they have a finite life span so replacements can be needed from time to time.
Although I have seen the message appear on cars when the battery is low so hopefully they’ll be a bit of a warning in advance!
Hi Nick. I have same car as you about 4 months old. This week my car kept sending me mails stating it was closing the car windows due to rain, every 20 secs or so. Went out and car completely dead. I put on my ctek5 for a whole day and nothing. Mercedes sent out RAC and they told me a Ctek will not charge a dead battery only keep it topped up. They connected theirs and away it went. They told me because I was retired and just did shopping trips the front battery could not cope. The front battery is only for the mbux system on the dash, everything else is from the rear battery which disconnects when front battery dies. Because of my lifestyle they told me to connect my Ctek when it’s in the garage. Did that and it’s ok now.
Ah okay, yes I mean it does depend on what mileage you do / how often the car is on. If it’s only very short trips then a trickle charger might be a good investment!
Which battery controls the start/stop,the main or the auxillary?
It depends on the car so you may have to ask the manufacturer 🤓
Some cars have two batteries, some have one battery that does it all 👍🏼
Hey Nick - Great vid! Side note though, i have a 1.3L A200 Premium Sport A Class 2019, a full tank usually costs £55-70+-, It says on the info screen that i get only max 198-200mil range? Surely i can get more range? I've seen other A Classes with same spec and engine go above 200 and 250mil? Thoughts?
The predicted range in most cars is based on the current average MPG. If you drive it like a hire car you'll get poor range.
Hey CertifiedMrTech,
Thank you! Yes I know the stat you mean. Honestly best thing, stop looking at it 😅 let me explain…I promise it’ll make sense!
Basically pretty much all cars have a trip computer and usually include a range indicator like on your car (same as mine).
It’s really useful however on some occasions you can look down and it’ll say 200 miles and then others 400 miles. The most I’ve seen is 420 ish I think.
As GoProflying mentioned it can be down to driving style but the most probable factor is where you’re driving. If you’re never getting above the speed of 40mph, you’ll never get more miles per tank of fuel. This is because most speeds under 40mph will encounter traffic in built up areas with lots of start / stops.
If you go on a long trip somewhere, watch what happens when fuel up, that mileage will shoot up. But then when you return to doing lots of smaller trips round town, it’ll very quickly go back down again.
It’s just the computer adjusting to where you’ve driven etc so although useful, not always accurate as it doesn’t know what trip you’re going to do next! Range computers will show you usually the last hundred or so miles of your driving etc
Hope that makes sense, message me back if you’re still not sure 🙏
@@npoleary thank you so much! You’re the best
If you have not already covered this topic, I would like to know more about where the MBUX system is manufactured, where the chips are from, its reliability, and the costs associated with fixing it, should it malfunction. I'd also like to know what the most likely failure is, and the effects of that. Years ago, engines reliability was the big thing, Today it seems that infotainment system reliability is the thing to look for.
Replied to your other message 🤓
Hey davesmith5656,
Yeah cars are these days! They have such sophisticated systems! 🤓
Really sorry I don’t know that, out all of the car manufacturers I review and produce content on I don’t think any of them explain that.
I would imagine they do most of the work in house, but of course some components are probably sourced elsewhere. For MBUX specifically I ran a quick internet search and found this if that helps?

I know they also use NVIDIA for their graphic chipsets too which is pretty cool!
In terms of costings, I wouldn’t know you’ll have to ask Mercedes. I do own one but it’s under warranty so if anything did happen it would be covered 👍🏼
@@npoleary---- Thanks. I've watched many videos and I've read many reviews, and all of them, if they bother to get beyond a showroom description, are about engines. The infotainment discussions are limited to features, with maybe only one or two passing mentions of reliability. You have to go to the comments to get any additional info (like how upset people are with them).
The manuals for the different years are combined even though the features and functions are different, so even there it's not so easy to figure out what's in the car package. Computers on wheels. Do you happen to know, if you have an electronic shift, if the MBUX, goes down, can you get the car into neutral to have it loaded onto a tow truck?
Quality and consistency of dealership service is also a huge issue. If the car is under warranty they probably do a good job and don't "leave something on the table". If it's out of warranty, which shop you take it to is a major decision. I've learned not to trust dealerships, and to choose shops carefully. E.g. take it for an oil change, and a month later the oil pump breaks, get that fixed, and a month later the alternator dies, get that fixed, and a month later a fuel pump malfunctions, etc.. They know what they're doing.
I'm thinking about a car kit. No computers, and I know how to fix it myself. Keeping a 60 year old classic is a lot of work.
Well the thing is with reviews in general especially when creating content, most reviewers or content creators or RUclipsrs will only have a short time with a brand new model. I can vouch for this, the shortest amount of time I’ve had with a new car is an hour 🤯 not good!
The longest is a week.
Unless one was bought, comments couldn’t really be made about reliability long term because of the short time with the cars. I have however bought a Mercedes A 180 last year so I could talk about that but everything’s all good at the moment, and as it should be! It’s brand new and a premium German car.
No manufacture is perfect though which is why last year I chose to diversify and cover more brands than I did before to help people make the right choice 👍🏼
@@npoleary ---- When I go to a car review video, I'm looking for (hoping for) more than a walk-around. I never really thought about doing uploads, or how to get permissions or whatever to review various cars, but I do appreciate that the industry is huge, and doing an in-depth on some new model would require a pretty extensive knowledge base to offer relevant comments and comparisons. It's the same sort of thing with surfing videos: they should explain the sea bed formations that produce the waves, and should show some footage of the waves from a distance - but do not. Mostly, you get very good to excellent shots of rides. There, it's very simple, compared to cars, and surfers probably know very well what's beneath them, but still, at best just passing mention of the sea bed under the waves.
Your "tips and tricks" are useful!
Vids talking about the beauty of grills and stitching and styling are not useful (I can see all that for myself). I do try to empathize with mechanics (technicians) - it's beyond me how they keep up, and it's the same with doctors, having to keep up with new journal articles and new procedures. There may be some summary database on car computer systems and reliability, and some data on whether or not there is partial failure or only comprehensive failure.
Hoping to find something I can rig to disable start stop on my car.
I forgot I had start/stop technology as I don’t do a lot of mileage in my GLA but had a long run the other day and it started working every time I stopped. I also notice if I go on holiday I get notifications is the app that my battery is low and needs charging. I’m planning to put the battery charger on a trickle charge the next time I leave it for a while. Ever had this issue with any car I’ve had in the past including Audi’s and BMW’s
Ah yes! A good run would charge it up
Well it depends of course how new / how old the car is. Starter batteries can last up to 5 years and even longer these days but luckily when cars are sold from main dealerships, they will usually check the battery health and replace if it’s not at optimum performance for peace of mind.
Newer cars draw more power than ever before with all of the tech in them! 🤓
Hi Nick I took delivery of a 2021 GLA250e and drove it over the weekend but noticed it didn’t seem to have start stop on there. Is this right or am I not doing something correctly. Any advise would be welcome. Thank you
Ah nice! I’m a bit confused by what you mean though…
A plug-in hybrid is a hybrid, it doesn’t have start / stop technology (as such) because it has an electric motor and separately an engine. So you’ll be driving on electric most of the time but if the electric is low for whatever reason then the engine will come on.
You missed one. I'm new to this tech (my previous car is 20 years old) - and the second time I drove my new car the start/stop didn't work ... because I had accidently turned it off on the switch under the start button.
Well there is the button as well haha 😂
Mine is a Kia Sportage coming out with engine management light and Auto stop start light on
Oh no that’s not good, sadly as with all cars an engine management light could mean all sorts of things. I wish their screens actually said what was wrong but annoyingly needs diagnostic equipment.
Pop it to a car garage / mechanic and they’ll be able to take a look and find out what’s going on 🙏
it seems like my cornering lights are not working on v-class mp 300d 4matic airmatic. can i turn them on? know that i have to turn the steering wheel 40km drive and so on. is there anything i can do myself?
Not tested them myself before but I did observe them coming on when the steering reached a certain angle. Although I’m not sure if it’s any different on the V-Class. What light system do you have? It’ll usually say on the exterior light housing somewhere.
LED High Performance Lights
MULTIBEAM LED etc
Jaguar Xe , not worked since I bought it . Had it four years.
Start stop on my 981 not worked for about four years all of sudden recently decided to work just one time Battery AGM will be ten years old this year. I’m expecting it to give up soon but until then it doesn’t matter as the stop start doesn’t bother me. Waste of energy you have to have a special and larger capacity battery costs third more than a standard and also more wear on electrical components I do have the option to switch it off when using vehicle. If you are stationary a long time I switch all off anyway I cannot see how it saves pollution as when you restart engine it technically wastes fuel on startup on any engine.
Good. Saves me from pressing the button to turn it off. 😀
How do you turn the bloody start stop off, I will hate it when I soon get my 2020 GLC 300. Will save buggar all fuel and more wear and tear on the car.
You’ll save fuel when the engine is off. So the more you spend in traffic the more fuel you’ll save with a system like this.
Start / Stop motors have been designed with start / stop in mind. It’s physically designed and rated to cope with more start / stops.
If it used the same tech as years ago, then yes that would be bad.
But if you want to turn it off per driving session, underneath the start / stop engine button then’s an “A” to toggle it off. Useful a quicker getaways pulling out from a roundabout or to keep the A/C on 👍🏼
HI Nick, do you have any idea about my C350e which the e-mode has not worked recently? There is no warning light, and the engine keeps going even when I'm waiting for the red light. The temperature outside is around 15 degrees. I'm so confused-
Oh really? That doesn’t sound quite right
It’s been a few years since I drove one but I’m pretty sure that was the All-Electric mode.
Have you spoken to a garage or dealership? I’m sure they’ll be able to check it out.
Does that function mess up car battery? Whenever I turn on my Mercedes c300, it is automatically activated.
I have been having problems with my car when I come to stop and hit the gas paddle to start my car moving again and sometimes it doesn’t start moving and the gas paddle doesn’t seem to function. I already had my battery replace and still having same problem.
Start / Stop won’t mess the battery up, they’re physically designed to handle more start / stops. The only difference is that they cost a bit more due to their battery density.
However what you’re describing doesn’t sound right so I’d suggest getting Mercedes or a mechanic to look at it and find out what’s going on.
@@npoleary thank you. I’ll take it to my dealer again.
the temperature of your coolant does not indicate whether the engine is warm this is a misconception the temperature of the coolant is in the middle within 5 minutes but the engine oil takes much longer to warm up so the coolant temperature does not indicate the engine temperature
True but sadly not many people have access to the exact oil temp on their car, mine certainly doesn’t! However…I have driven a couple of cars before that do have it!
What about the auxiliary battery being low?
Think that's what he means regarding the battery being low
Auxiliary battery is the start / stop system 🤓
Unless it’s a battery for something else, a campervan for example may have an auxiliary battery but that’ll power the fridge / freezer / lights etc
@@gavinspringett To my understanding (I am not a technician), the auxiliary battery is a second (smaller) battery, mainly supporting the electronics in the car. Depending on the model, it might be located under the glove compartment or the boot, e.t.a. The main battery (under the hood) supplies power to the started motor and other power intensive equipment, not the auxiliary battery.
Hi Nick, I own a Mercedes C200 from 2016. When I first had it I was able to go into the computer thingy and turn off the default for the stop/start but ever since having the battery replaced this no longer works. It appears as though it's off on the display but the only way I can turn it off is pressing the green button on the centre console each time I go out in it. Have you any ideas what's going on and how I can turn it off by default again? Mark.
Hey Mark, ah nice!
Well the start / stop or stop / start tech is always controlled using a button (usually with green icon). This is how you turn it on/off per driving session.
Same for all cars, don’t think I’ve seen one any different
Have always seen it as yellow in my car and never green. Could this be an issue with battery? I have had long journeys in summer and winter but never seen it other than yellow.
Possibly, I mean it could be worth checking it out. Maybe ask a dealer or garage to have a look when it’s next in for service or something.
I had a C Class 250 coupe and had an issue with engine warning light. Diagnostics revealed a failed NOX Sensor. Replaced a few times but Start/Stop tech failed repeatedly. Never got to the bottom of the issue.
Oh strange, have you taken it back to the garage that carried out the work?
@@npoleary Yes, It went back every time and they fitted a new NOX sensor. The Start/Stop operated for a short time and then spuriously. All this was done under warranty but it was annoying. Change car last year for a GLC 300 Coupe. Love it! No issues.
Can we turn it off completely without having to turn it off everytime you start the car?
No sadly not, it’s emissions requirements that manufacturers have to have it auto enable on an engine start but it can be switched off per session if needed.
Thank you for the reply@@npoleary
@@thinneshmuniandy7200I have Ford Kuga. I hate this oeice of kit. Hardly ever works at all. But i can turn it of permanently by going into settings.
I sometime drive a friend's car with it. I hate it. Most stupid idea ever. Will destroy engine over time.
I have a Renault Captur. It never works, always showing priority battery charging. It is so battery hungry even when sitting outside the house it can never recharge fully. I drive jt around sll day and it is still showing priority battery charging..
Isn't it Stop/Start rather than Start/Stop?
10 years? I had it on a VW Polo in 1984 so it has been around for 40 years!
A few years ago my C class just never did it and about 6 months later I needed a new battery and then it worked so it is a good indicator that the battery is not at its best.
I must say Mercedes have it just right as to when it cuts out in and re-starts. Wife's Peugeot has it, you stop and it cuts out, then passenger opens the door to get out and that starts the engine!
I get a 12 V warning even when I do my daily 40 km trip. Need to drive more they told me at the garage. Hey Mercedes ?
I would ask them to do a battery health check and see if there’s a battery drain. Although I should add I’m not a technician or anything like that so I’d ask them to take a closer look.
Driving 40km a day should be plenty!
Can you help? I have a2014 crafter ever time I start my engine it beeps and says start stop error?
My battery is a year old. Not sure what else it is?
Really sorry if it’s not anything in the list in the video then it could be mechanical related so probably best to get a dealer or mechanic to check it out. If the battery is only a year old, can you speak to the person who changed it?
@@npoleary I did the battery cost me nearly £300 the garage wanted etc money to fit it. The battery reading over 13volts before starting it. So I’m not sure what’s up but when I scan my van it’s saying there’s a air temperature sensor needs changing quoting number p007d
Hmmm strange
Really sorry I’ve not worked on cars from a mechanical point of view so wouldn’t know what to suggest apart from going to a mechanic. That’s what I would do anyway, either that or a dealer if it had a warranty etc.
@@npoleary it’s a lwb Vw crafter 2014. Pannel van that I’ve turned into a camper van. Own it since 2018 never had a problem with it till after Christmas it started playing up with other things too
Oh I see, really sorry I initially thought you meant A-Class (wasn’t sure what crafter meant) I’ve only ever been in passengers cars that Mercedes offer so never in their vans. I might look to cover them on the future though!
I know the insides of them can be a little different from what I’ve heard.
It has never wworked in my 2019 Ceed Gt Line, always displaying the amber light no matter what time of year it is. Ive no plans to ever address this as it was something I absolutely hated in my previous car.
ah fair enough....at least it's permanently off now 😅
You mention that if you've used several start/stops in succession short time then it won't work until the battery has been charged yet we were led to understand that it was designed for being in queuing traffic to reduce emissions 🤷♂️
Yeah exactly 🤓
It’ll help with a few start stops (and I mean quite literally back to back) but if the voltage drops too low then it’ll stay on for a little while to charge back up.
Quick succession I mean is literally one after the other, if it’s spread out over a few minutes or so then it’ll be able to do a few.
In the best cars if you Want your engine to `stop` in traffic you just turn a Key. You dont have the Worry of the Ambient temp, rate of speed/distance travelled, whether you`ve wet yourself or the battery doesn`t like the weather conditions?. Key! ,you don`t even have to look, it`s the Most Accessable thing in the effin Car!
Replaced my aux battery and now it says charging and that is for the last month it will not charge even though it says it is charging so Idk what is going on it is crazy gonna have to go to the steelership
Hmm yeah if none of the things in this video work and you’ve even changed a battery I’d suggest chatting with a mechanic or dealer. They’ll be able to sort it 🤓
Evening aka Mr'O
Good Evening Mr Jack 😜
Start stop, the most hated feature on modern cars. I disable it everytime.
I hate this crap on my 580. I have to get used to turn it off as soon as I turn the car on.
If you have Sport+ feature turned on or Race mode, the start/stop feature wont work.
Very true! I’ve seen that before! 🤓
