And now the engine light is on ...but I noticed my breaks have been acting like there in abs mode..like I'm sliding out of control..can u help
Thanks for video I started and turned off 3 times in a row and it went away it’s self✊🏼
HI @kevinzgherea2856 Great result! Sometimes a glitch can cause the CEL to come on and a rest or two is all you need. Fingers crossed it stays away for you! 🤞 Cheers, Phil

Ha ha, yes, that’s a lot less trouble! 😂

Thanks! 👍😎
Would u believe it, but when i did the clk service i didnt turn the ignition/ prime the system after changing fuel filter, and when i went to start it, it coughed a few times but started up ehh but engine management light came on. When i put my obd on it had P0336 code, crankcase sensor !!
I erased it and now after a week it has not reappeared.
Do u think the fault code was just activated due to lack of fuel and that there us nothing wrong with crankcase sensor ???
Hi @arnietwo11 I’ve never come across the CEL coming on from a fail to start before but surely it can’t be a coincidence! You’ve done exactly what I would do, which is to reset it and see what happens. Amazing how many times a sensor has a momentary wobbler but once reset doesn’t do it again! Fingers crossed that’s the case for you! Cheers, Phil
My c class 2005 diesel has engine light on. It did reset at some point but quickly got back on. It was shaking a bit at lower revs and then continued but with engine light on which limited the speed. DO you know what shall I do in this case?
Hi @aleksandardjelic4369 As your check engine light is on, there will be a fault code logged in the ECU. You need to read the code with your fault code reader, then Google it, that will be your starting point. Thanks, Phil
did you find out what this error was. I have this on my gas GLC
Can I ask did your engine light come back on?
Out Eclass has the same fault code in which I cleared the code,unfortunately the engine light reappeared within days.
Hi @paulnunn8185 yes, unfortunately, it came back on. On my car, It is one of the Nox sensors that is out of range. I’m afraid you only really have two choices to sort it out: 1) Get it checked by someone that has Star or Xentry fault diagnosis, just to ensure it is fully understood exactly what is wrong (just the sensor, or maybe more). The problem with this option is sensors are currently out of stock, so you could be waiting a while and the repair is expensive and may just reoccur (it turns out that on my 2018 car, they have already been replaced once on warranty but Mercedes aren’t offering to do it again). 2) You can have an Adblue delete carried out at a Mercedes tuning company that disables the system. It will still pass MOT but potentially your Nox emission levels will be slightly higher than before. I hope that helps! Thanks, Phil
I recently bought a E220d and the engine management light has come on yesterday. I checked the code with my Obd scanner and its come back as "Communication lost with Nox B sensor"
It's apparently a common fault with these cars. Iv still got warranty on the car and I'm hoping the garage will fix it for me. I've done some research and them Nox sensor are about £500. 😯
@meahmeah2279 Honestly, don't get me started about it! Mine were all replaced under warranty by the previous owner and then failed again for me! On a 2018 car! There is definitely a hug problem here! BTW, a lot of these components are on back order. You will need to really push for them to do it under warranty but there is no way this is a "consumable wear and tear part at this age and mileage" Good luck with it! Thanks, Phil
@@ReviveMyRide thanks for the reply, I've recently bought mine, it's a 2017 E220d. Today it's showing up on the display "start engine see owners manual" so that must mean the battery is on its way out. I wonder if that could be the reason the engine management light is on and showing the Nox sensor on the OBD scanner. I'm going to fit a new battery tomorrow and see what happens. I bought a Mercedes thinking it's going to be a reliable car and now I'm spending money on it already. I really don't have any luck with cars. I've only driven it 1,000 miles. 😢🤦♂️
@meahmeah2279 Yep, I had the same thing with my Mercedes. Was assuming next to no problems with these cars and then I had both issues that you have mentioned. New battery should fix the "Start engine" warning but I doubt it will fix the CEL. Regarding the NOX sensors, this is just my experience: Mine were replaced under warranty by the previous owner (it was about £1k worth of work), then they failed again for me, no longer covered by warranty and this is on a 2018 car. A lot of these sensors are out of stock with Mercedes because they are having so many problems. It was a difficult decision but I decided to have the Nox sensors "mapped out" because having failed twice in 4yrs, the NOX system appears to be not fit for purpose. If you are interested in this, look for recommendations for reviews for Mercedes tuners / mappers near you on google and then give a few a call. Hope that helps, Phil
So if I have a p2759 stored code, it says torque converter solenoid elec. Will it be the solenoid in the valve body of the transmission? Thanks any feed back welcome.
Really sorry, I haven't come across this problem myself, so I've no idea. Sorry I can't be of more help! Cheers,
Phil
Mine had a momentary flash after I accelerated hard. So I pulled over , turned the engine off , and waited a minute. Then it was ok… hopefully it will stay that way
Agree, hopefully it never comes back and tbh, sometimes that's it, so it's always good policy to see if the problem recurs before taking any further action. If you have access to a fault code reader, they may be a code logged in the ECU. Cheers, Phil
@@ReviveMyRide thanks for your advice. Yeah that’s a good idea , I’ll have a look at some good quality scanners
@@SheerMagnetismDarling007 If It helps, I've had good results on Mercedes cars with the following: NexPeak NX501 (Fairly standard type of code reader, can read everything but may not be able to reset everything) & TopDon Artidiag 800BT (can read and clear all faults). Thanks, Phil
2023 C43 AMG with just under 9000 miles on it.
My Check Engine Light came on after I was trying to get the Speed limiter feature to work (spoiler alert- when you have smart cruise control, there is no such feature - at least in the USA, which is fine by me.)
The light fixed itself after turning the car off and restarting a couple of times.
It did not like my holding the Resume button for a few seconds with the cruise control turned OFF.
I won’t do that again!
Thanks for sharing your experience, there are a LOT of things that can cause the CEL on a modern Merc! Beautiful car btw 👍 Cheers, Phil

No probs! Hope it helped you 👍

I put in add blue and then it said add blue level cannot be checked. Engine management light is on. Any idea what this could be ??
It sounds like your adblue level sensor or pump has stopped working. Here is a post about it on a Mercedes forum which will give you some more information: forums.mercedesclub.org.uk/index.php?threads/adblue-not-reading-level.188057/ What I will say (and I don't mean to worry you!) is that the entire adblue system is a bit of a nightmare and prone to sporadic faults. I think MB rushed it in to meet an emissions deadline. Because some owners feel the system is not fit for purpose and extortionately expensive to have repaired (only to subsequently fail again), they actually have it "mapped out" and disconnected. Any reputable Mercedes tuning specialist can do this. Not everyone agrees with this approach but I can see it both ways. Hope that helps, thanks, Phil
I pump 87 gas in my 2013 c250 and the check engine light came on also it’s misfiring, what should I do??
Hi @romainefacey2360 I honestly have never come across this before! Is the car designed to run on 87? If not, you should get someone to drain the tank for you. Thanks, Phil
What's the most common cause for checklight flashing
Honestly, I don't think there is a most common cause! It seems there are 101 potential causes, the best way to start looking into it is definitely to read the code otherwise you will get nowhere. Sorry, hope that still helps some... Thanks, Phil
I am having the same issue in 2017 C class. Took it to the local garage, and they removed it. Unfortunately, it has come back after a week. Garage suggested that one of the NOX sensor is not working, and it would cost £800. Prior to this problem, I had an issue with the battery. After a good run, the battery issue no longer exists. So, what should I do? Change battery or faulty NOX sensor? Any advice is much appreciated. Thank you.
@budobaaje6160 On my car, It is one of the Nox sensors that is out of range. I’m afraid you only really have two choices to sort it out: 1) Get it checked by someone that has Star or Xentry fault diagnosis, just to ensure it is fully understood exactly what is wrong (just the sensor, or maybe more).

@Revive My Ride Thank you, Phil. I have booked an appointment with a Mercedes authorised garage this Thursday. God knows what they gonna come up with. One thing I know is, it's not gonna be cheap. Thank you anyway.
@Budo Baaje No probs, good luck with it! I was really disappointed that my car had this problem twice in 4yrs and Mercedes just weren't interested!
@@budobaaje6160 hey, can you tell me how everything went please?
Hi, budo. Can you tell me what follows about the NOx sensor and engine management light? Thank you very much indeed!
Engine light on my A class 180d how do I go about getting it away
Hi @ferdiamckenna8593 as shown in the video sometimes the engine light is caused by a momentary "blip" from a sensor and if you are lucky, you can clear it and it will stay away. This is definitely worth a try as a first step. However, if the light comes back on or won't clear, you have to read the code to see what the problem is. Then, you need to fix the problem (or have it fixed) and finally, once the issue is resolved, you can clear the code. The code reader I used in this video for that is called a NexPeak NX-501 and you can find it here: UK Link: amzn.to/3DGRDU2 USA Link: amzn.to/3NkNw36 Hope that helps! Thanks, Phil
I got a 2012 Vito, RH Drive.
How to off Check engine lamp without scaner
There is a way to get the last reported engine management code to be flagged to you with out having to connect a scanner. it was a process to do with the key being inserted, removed, reinserted and turn a number of times and a dash light pulsing, found it tricky when I had an issue with my Vito where by it went into limp mode.
@ABzrak Thanks for sharing that info, sounds interesting! Will have to look it up and give this a try 👍
Common reasons check engine light 2016 Mercedes Benz
Hi, here is a link to the most common causes www.mercedesbenzgreenway.com/service/check-engine-light.htm but if you have got a check engine light, there are so many possible causes that your only real option is to read the codes and see what it is saying. Hope that helps! Thanks, Phil
I got a 2017 c180 and it does shows the light
Hi @AkaniNkanyani-uc1kz hopefully it isn't too serious. Now what you need (if you don't already have one) is a fault code reader (in the video I use an Nexpeak NX501 amzn.to/3DGRDU2 ) so that you can do a reset and check to see what the fault is, as shown at 02:20 in the video. It is worth trying to reset the Check Engine Light first and see if it comes back again but if it does come back on, then there is probably something that needs to be fixed. Thanks, Phil
My check engine came once for coil issue, second time it was the fuel pump gas kit….
Yeah, there's lots of things that can make it come on! The fault codes are so useful for pointing you in the right direction 👍
Mercedes car is no longer reliable as we paid for it, they rubbed every customer. I have another car Kia Rio for driving lesson, there no single fault for 10 years but Mercedes always something wrong
@bestSchoolofMotoring I agree, the Mercedes cars do seem to have become very complicated and seem to be having more problems than in the past!
I agree
Totally agree
For the amount of money it's definitely not holding its value. I have a nissan sentra and it's older than my Mercedes and really no issues. But this Mercedes s550 is really beginning to be a headache
remember, the e class is the most reliable Mercedes, mine has served me perfect for the last 150k miles and I've only done regular services on it, the only issue I faced was replacing the auxiliary battery at around 65k miles and it only cost a few hundred bucks
@@charlesm251..in many cases it's true...
Engine light came on 2008 S550 .
Sorry to hear, there are many possible causes, all you can do read the codes as per the video and check into whatever you find... Thanks, Phil
the check engine light has come on on my 2014 250 CDI W204, the local garage plugged in their tool and it said exhaust, DPF? I put a DPF cleaner additive in the tank will this resolve the problem if that's what it is?
Hi, sorry, my honest answer is I don’t know 🤷♂️ because I’ve been lucky enough to avoid dpf and egr issues with my cars so far (long May it continue). From what I have heard, the additives can help prevent the problem but not cure it once you’ve got it. I suspect you may have to go to a company that specialises in removing the dpf, cleaning it and refitting it again. Thanks, Phil
@@ReviveMyRide I used liqui molly in tank DPF cleaner and took her for a run on the highway.. light went off 😉👍🏼
@@MrBlompod Wow, sounds great! Thanks for the update, I'll give that a try if I get a similar issues!
I have a 64 A class and brought it brand new. The engine light came on 3yrs ago. I’ve spend 1000s on diagnostics and nobody has been able to identify and fix rhe problem. Mercedes are no longer reliable as they use to be.
Sorry to hear about your troubles, it can be tough when things are going wrong and the "experts" can't find a thing despite you paying for diagnostics ☹
Between BMW and Mercedes, ill get a Toyota or Honda. Euro cars is a big headache. Too expensive and very UNRELIABLE!
I love my Mercedes but you're absolutely right, reliability from the German car makers has really gone down! You might find the JD Power reliability awards interesting. The top 5 brands in the US are currently Lexus (part of Toyota), Genesis (part of Hyundai), Kian, Buick and Chevy! But yes, Toyota are also good with Honda kinda mid pack... Thanks, Phil www.jdpower.com/business/press-releases/2023-us-vehicle-dependability-studyvds
This video was 0% help
Sorry you feel that way. The video was intentionally generic and has helped a lot of people to learn how to read their codes and once the problem is fixed, what's involved in resetting it. I accept that once they know the code, the actually "fix" will vary because there are a lot of things that can cause a CEL to come on. Cheers, Phil
