Love your videos, as an armchair mechanic.
However, you keep saying “crank, no start”.
Shouldn’t it be “no crank, no start”…?
Had no idea modern cars have a P-brake “pawl” battery. Very interesting…
Keep you videos coming, much appreciated! 🙏
Dan you are a genius
Just curious did you check if the axillary battery was getting charged.
RIP OFF ARTISTS DAN MY MAN
@@sandysaab9357you are right i noticed that when i was editing the video but than it was to late🤣
Not a finer auto technician on RUclips. Not only a brilliant diagnostician, but impeccable presentation and explanation! Simply the best!
SMA tho...
@@jonathanfenne4948 what about SMA ??? Diagnose Dan is more of an auto Electrician, where as Eric ’O is more of mechanical technician. Hopefully you can see that difference, right??
Thanks for the great compliment!
@@jonathanfenne4948Eric is a great colleague with a very enjoyable channel 👌
Facts
Outstanding job, Dan. Not only are your superior diagnostic skills apparent working on this vehicle but also your superb teaching skills as you took us along so we can learn. Your videos are fantastic.
Thank you very much thats a great comment sir
Outstanding job. Glad you were able to fix the car and sell it. You're the only mechanic that fixed the issue when other shops failed to fix or diagnose properly.
@@Terost36😁😁
my guess is there is a lnown issue with the original SAM module which is why it has been superceded and as Mercedes are expecting a high level of failure they lower the price expecting to move a higher volume nice work as always Dan
In that case, a Technical Service Bulletin should have been issued by Mercedes and DDTSB should have an entry for that.
@@MooseOnEarth a tsb is not a recall, car owners are not notified and neither are mechanics, they have to "search" for these symptoms and not everyone is as smart as Dan.
I'm not familiar with this type of A class,but in 4 years a vital module to go bad 😔. No wonder the customer stated that out of the blue there was no crank.
In some cars at that location it gets hot. So eather there was a bad manufacturing or bad design.
Most times bad manufacturing will not be a reason to change the part number of the part. So bad design is my guess.
Now to be fare, Mercedes could have decided to use this module in other new vehicles or they might have changed something for the newer facelifts. This could be a reason to redo the design of the module in order to work for all versions of cars. Or they messed up in the first place and do not accept the blame, to be fare .
@@vehicle-stuff Could be as simple as an electrolytic capacitor failing.
@@ianmontgomery7534 A board repair specialist will find the problem. Here the main thing is that the part is not working and has a new number /99% something is changed in it/.
Have you ever come across a car you couldn't diagnose/Fix dan. You're the best mate.Amazing work.
Yes that happens, but thats usually because the customer doesn't want me to invest more time.
@@Diagnosedan Gotcha
It is always a pleasure follow Dan in his journey to troubleshoot cars using profound knowledge and logic. A true expert that makes every work seem "simple".
Thanks for watching!
Just happened to pass by your channel and I was impressed by how you lay information and simplify things. Your behavior, the way of explaining things and just the clean execution (and I mean clean in every aspect) demonstrates that you're very knowledgeable and a master of your craft. God bless you and I wish you the best.
I very much look forward to a video on the rest of the issues like the cooling system being near-empty and dealing with all the other DTCs. Luckily, this car does not look like totally torn apart and tinkered with by previous workshops.
The cooling system is completely empty🤷 If i think its going to be interesting i'm going to film more issues on this car
@@Diagnosedanhad multiple w177 a-classes with a thermostat housing leakage.
Good techs like Dan seem to be more rare everyday. Good work Dan!
They have been rare for years, dealerships are awful at paying as low as possible.
They are out there, you just need to find them👍
Outstanding video!
On the original module I would trace the red/pink wire from the connector to the IC that controls it. possibly a solid state relay or a mosfet. Next check datasheet, find input and probe the input with a scope. Pretty much the same fault finding technique but on a board level.
For the cost of the replacement module it may not be worth it but it gives a closure and satisfies curiosity 😅
You are right i suspect a faulty transistor/Mosfet. But the new board is proberbly better than the old partnumber. And for that price i'm not going to invest to much time
honestly not the trickiest troubleshooting I have seen you do, strange that no other shop could fix it, the diagnose tool really pointed you in the right direction and it is not the first time there is a no crank no start because of circuit 15 relay has no ground due to a faulty computer. The backup battery however was new to me, great job and thanks for sharing
My pleasure
All I need in my life is a little whiskey and a DD video. You’re the best, Dan!!
😂😂
Dan makes it sound easy without even a single drop of drama. That's just amazing.
I'm trying not to dramatize or overcomplicate things. Its hard enough as it is!
You make diagnosing complex faults seem so simple as your logical conclusions are so sensible and meaningful. Top marks to you. I
think your technical skills amazing
and you are the best!
Yes, simply the best !😊
Thank you Sir 👍
There is no better teacher for this stuff than our Dan. Thank you, Dan. I can't wait for next videos! ❤
Hope to see you again at the next video 👍
One of the most interesting/informative channels on diags on youtube! Most shops would turn down this car as a waste of time.
Thanks !!!!
We need people of your talent in Singapore! That will raise the standard of diagnosting and repairs significantly!
Dan, absolutely fantastic and very happy you will make a good profit on this one. I think your approach to these issues is so logical and it goes to prove that even in these modern times with more and more complex electronics that a competent DIY’er with a decent multimeter, test light and power probe can confidently identify the source of the fault.
Still some work to be done but at least its running again
Wrong ... Dont forget the wiring diagrams , the tsb and service data to decipher vehicle module legends and locations . Without these helpers you can multiply your competent diyer fault finding x100 and the car would have to be stripped so much to follow wires it would not be worth it
You really are a hero among technicians. I have come to appreciate your videos and wanted to say, Thank you sir for the videos you post. Very easy to follow along with and you have a voice made for the camera!
Thanks!👍👍👍
For me as a diagnostic technician at MB, it is incomprehensible that so many workshops had problems finding the faults. If, as Dan did, you look at the important error codes and ignore the consequential errors, then you can find and repair the error quite quickly. The workshops previously involved did not show themselves to be competent... I can understand the frustration of vehicle owners.
You’re wonderful Dan,I’m glad to be one of your subscribers.
Great to have you here👍
Top work, you make it seem so obvious! While everyone else scratches their heads....
😂👍
Awesome work again, DD!
This stuff fires me up!!
It's a bit of a shocker a module like that craps out at 3 yrs, but a nice surprise on the replacement cost!
Well done! 🙌🏼
You are right that module should have lasted a long time
@@Diagnosedan Maybe there is a common fault / production issue and thats why the module got cheaper in price... Maybe there are known to fail...
Diagnose Dan Fixed it again! It amazes me how if you follow a diagnostic process, it eliminates all variables as you continue. Thanks Dan!
Thanks for watching!
Hey mate, I just wanted to tell you that other car repair shops are being pissed with you right now. It's like that, because you actually have conscience. They dont want to help others like you do. I had a mercedes and sold it because i was tired of people not being able to fix those little issues on my car. I couldn't find a decent guy like you who could help me. Its really sad i did watch the audi e tron video with the automatic transmission problems from just a gasket and solenoid. Saying thank you for what you do simply isn't enough. I just wish that more people can be that way and help others. Its really sad, not because of the car sitting for one year, but because we as people are worse than animals, we are monsters who would go so low to screw one another over some pieces of paper called "money". Instead of that we can just help each other, like you are doing. God bless you for that man! Loving your videos and i'm also frustrated about my merc aswell, if i knew a guy like you i would pay double for the work! You deserve it, best wishes from Bulgaria 🙂
Brilliant job Dan!! What's really surprising is that nobody else had any idea where to look for the fault. 🤷🤷
🤷🤷🤷🤷
As always Dan, you make it look easy to diagnose the problems. Thank you so much for sharing and looking forward to seeing part 2 of the Mercedes. 👍👍
If something interesting comes out of it i'll film it👍
Great work diagnosing this car. I'm amazed that a 2019 car already has electrical issues like this that caused someone to abandon it for 12 months. They really don't make them for longevity anymore.
My son has that model so I've told him to buy a battery to swop over. Such a cheap fix. You are excellent at what you do and so methodical. Plus plenty of test and diagnostic equipment.
Great diagnosis and repair, Dan! Wow a 2019 that turned into a beached whale because of a bad module? Not very reliable! Can't believe the new module didn't cost 1000 dollars haha :)
Mercedes parts usually are quite affordable over here Ivan, but this one was cheap. These modules are known for many issues (not this particular fault) and the new partnumber should take care of that.
Ivan, I noticed the 21% sales tax. 😳 ouch!!!
@@mikenonameneeded3485 Here in Germany it is 19% and they talk to raise it...
@@TrekZero thats not good. Where I live in the states it is 10.25%. It should be 6%...
Simply amazing! I would be very intimidated by such a job... You make everything look simple because of your talent.
DD has all the necessary tools, and then some more, that helps !
But only if you have a brilliant diagnostic mind like Dan, and that he has achieved with years of hard work and perseverance !
Experience
Great Video as usual, many love from Saudi Arabia, as an ITC Engineer I enjoyed proper troubleshooting, I hope next time you film the process to program the Module, thanks for this informative video.🌹
My pleasure
Great stuff again Dan, really easy to watch and learn, I've been a commercial technician for 30 years and after watching your videos I'm venturing into the car industry for a new challenge. Thank you again 👍
Love your videos Dan.
If MB dealer had this module in stock off the shelf, it's likely mean it's a common failure on this car.
I bet there was a recall and replaced for free.
It actually was delivered overnight from a German warehouse. We are located only a 2 hour drive from the German border
@@loufaiella3354🤣🤣 Nothing is free over here
@@Diagnosedan 21% taxes added? Wow, so glad I dont live where you do.
That explains the Dutch text on screen 🤣@@Diagnosedan
Be good to see a video of the next steps with the car and the finished car on the road
Maybe😊
There is no one like you in youtube , you are the best of the best
Well done! This is how a diagnosis is supposed to be done. When mechanics just start replacing components and charge the customer that is a crime. Prove the trouble then charge the customer.
It isn't often you get a solid win on cars, But it looks like you may have just pulled it off Dan.... Always exciting to watch you diagnose these faults mate... This was a particularly good video man. loved it...
Thanks i'm glad you liked the video 💪
You make it look so easy Dan. Great content as always.
It looks easy but as you know it isn't always as easy as it looks! Thanks for watching
Great job Dan, as usual! Thanks for sharing, regards Nico.
Bedankt weer Nico
Great video Dan ,looks like your going to make some Euros out of this car.... i would just like to say that it was great to see you and Steve from simply diagnostics at the NEC in birmingham the other week at Mecanika .......
Same here,enjoyed speaking to both of them…
Birmingham was great and it was fantastic to meet some of you guys😁
Great work Dan. More techs need to strive to be as good as you.
Thanks for watching 😊
What a fantastic video from you Dan. It always amazes me how you go about diagnosing these faults. Like to have an update on this car and did you make a profit!! Good job keep it up.
Thanks for watching
Another fantastic video Dan, i need to tow all the broken down car's from here to you, and maybe we can split a share out once you have them diagnosed and fixed 🙂
This guy is a legend! Love the way he diagnoses cars , honestly this channel is a must for anyone trying to diagnose faults on a car .
Nice fix!
Btw, i would love to see a video where you fix other issues so the car is in good shape again! I know its not quite what you normally do but i love that kinda videos. 🙂 Its just so satisfying to see cars get repaired and how nice they end up getting. 😛
Maybe👍 Thanks for the comment. Have a great weekend
Programming the module would've been educational. I was very curious to see the Top Don in action.
I wondered if it would add anything to the video as it is only pushing a button and wait for the module to be programmed
A salute to a master technician. A mechanic's mechanic!
Hello from Northern Ireland !! 👍🇬🇧
I thoroughly enjoyed your diagnostics of that Mercedes!!
Thank you for sharing.
I eagerly await your next video 👍👍👍
Thanks! See you for the next one
Good stuff Dan! Always look forward to another diagnosis video.
Great!
fantastic work Dan, as expected .
Thanks as always!
All of your diagnostics are like forensic detective stories, fantastic.
More top level thorough diagnosis work Dan. You were under a lot of pressure to get that one going 🍻
🤣 The thing is the sales department think they can buy anything because i can fix it🤣 Maybe i need to say i can't fix it and they will stop buying these kind of projects
@@Diagnosedan or invest in a Snap On Magic Wand 😆
Great video as always Dan. Hopefully your company can make a nice profit on the car😊
Lets hope so, than we can pay the bills for al the new tools i want to buy😂😂😂
Very good tone of voice, speed of explanation and details provided. And without working in this field, it makes you watch until the end. Thank you 🇹🇩
Thank you for the nice feedback its appriciated 😊
Thanks Dan, enjoyed the journey with you, you deserve a raise.
For sure😂😂😂
Always remember kids: don't get overwhelmed from to many fault codes. Break it down to the essentials and go on step by step.
Nice job, Dan!
I'm wondering why the customer didn't go to an official MB Service?
He rather decided to try different shops and spent a year to get this fixed 😮
I dont know i've not spoken to him directly.
Don't bye a car that can have that many faults
I would erase the entire car and start over, which I'm sure Dan did
Can't say it enough, Dan, these videos are so super entertaining. Nice car too. So odd that people let these expensive things sit for a year, or that nobody was able to diagnose it properly. You should be called Sherlock Dan fixed it again hahahaha. Goed Gedaan!!
🤣🤣Thanks!
Always fun to watch your step by step eliminating problems, and logically working on.
It also, every time, reminds me of why I drive with an eighities car myself!
🤣🤣👍
I rarely thumbs up or subscribe to anything but being an ex mechanic I really enjoyed your detailed diagnosis.
Top Work Dan. Subscribed 👍
Greetings from Romania !!!
Me to
When you have a hunch and it turns out to bee right. That's a great feeling isn't it. Nice video Dan. I can't belive this car couldn't be fixed whit all does fault codes basically telling the whole story about what's happening 😂
Everything can be fixed😂
Thanks for bringing us along for the ride, glad to see the diag process lead to not over spending 👍👍
Yes that was a nice bonus, but still some work to be done !
Top video! Misschien een condensatortje of een diode die niet meer functioneert. Opzich vrij makkelijk te testen. Ik hoop dat de overige codes interessant genoeg zijn om te filmen ik ben benieuwd door hoeveel hoepeltjes je nog moet springen. Keep up the good work! 💪🏻
Waarschijnlijk een transistor/Mosfet probleem maar deze modules staan bekend om veel problemen ( deze was nieuw voor mij) en het nieuwe onderdeel nummer moet veel van de bekende problemen oplossen. De vraag is ook hoeveel tijd en moeite wil je investeren voor een redelijk betaalbaar moduul. Ik denk inderdaad dat er nog wel wat werk aan deze auto zit en als dat interessant lijkt te zijn zal ik de camera weer aanzetten!
You know they have discounted the Sam Module because they know the OEM module is defective…..You Rock Dan….🤟🏻🇺🇸🇺🇸🇺🇸
Thanks😁💪👍
Excellent ! I'm very pleased we were there to help you, I know I couldn't of done that on my own! You are a clever methodical man.
Thanks for your help😉
It's a no crank no wash
🤣🤣
You might fix it, but in the end it's still a Mercedes :P
😁👍
Brilliant, this guy knows a thing or two about car engines & more importantly he knows how to fix them, Well done sir.
Not a chance of me ever managing to even find the ladder which you are on the top rung of .. brilliant / unbelievable . my hero ..you are the man .. etc etc .. you make it seem so darn easy and straightforward .
I really like this guy, he's got that instantly trustworthy feel about him.
Always fun for a retired factory troubleshooter to watch you - I learn new things and greatly enjoy you presentations.
Thanks you must have done alot of fault finding yourself!
@@Diagnosedan True - and started with auto repair at 15 with my Father who was rebuilding an MGB. At 70+ I still enjoy learning.
Looks like you are on the hook with this car ! First hurdle overcome now she starts and runs . Good luck with the rest.
Thanks I'm going to need it! 😂
Great work Dan. It’s amazing how other so called shops can’t diagnose these things yet charge to try doing so
Thanks for watching!
this guy needs his own tv channel !!!! congrats Dan
🤣🤣👍
Excellent information...Thank you Dan for making diagnosis more informed.
Thanks for watching!
Excellent channel. - Thank you. - I’m retired street trolly tech. troubleshooting is valuable part fixing electrical problems. Not just throwing expensive parts at the vehicle and hopping for a fix. Often that will cause more trouble.
Thanks for watching!
Brilliant as always Dan
Thank you for taking time to share your knowledge and expertise
My pleasure
Incredible diagnosis. Thank you from Texas. I’m learning so that I can diagnose my no-start/no-crank 2005 Land Rover LR3.
Love your methodical approach to troubleshooting!
Thanks!
As usual, Dan "hits" again and makes the car start again. Keep up the good work Dan
Thanks! I will or at least i'll try🤣🤣
One of the best Automotive Diagnostic Technicians out here. Thank you for a very rewarding video.
Thanks for the great comment
I was pleased with your knowledge and teaching skills and explaining as you went along ... and your smile as you explained what you did 10/10
Great diagnosis and explanation Dan! Very much appreciated
My respect to you ,you are a professional in the field ,that's why I never tire of watching your videos thank you , teacher for sharing your knowledge
Great comment. Thanks👍👍
Love the video,really good to see how professional diagnose faults,👍
I can't stop watching your videos. High-quality content is provided every single time.
Wow. You made my day
Very clear and logical down sizing of the problem. Thanks
As a electronic engineer myself, I’ve noticed that if spare parts are obsolete, mainly due to often breakdown, especially in a normal lifetime of a piece of equipment, it is replaced by an upgrade, better quality part.
There is also the new number coming from 😉.
That could also being an indication that you’re on the right track.
Thanks for taking me along… 🙏🏻
My pleasure 😊😊
Awesome diagnosis and fix Dan. Nice work.
Thanks!
The master at work again. When i get a notification that diagnose Dan, bernie Thomson, ivan from pine hollow put a video up im like a kid in a sweet shop. Another fantastic video. Look forward to the next one!
See you for the next one👍
Brilliant Dan, I can’t remember how many “dashboards eye distorted as an apprentice in a Ford Dealership !
But all was well after applying a few “ rolls of electrical tape.
Living on the edge, I went on to “ run an enormous Oil Refinery in the New Forrest”, with no issues hopefully .
Bravo man, bravo.. I work with these cars as a mechanic at dealership and this was valuable info.
Thats great to hear
DD is a veritable genius, worth his weight in gold !
You made a bit of money on this one, Dan !🎉😅😂😊
Glad you enjoyed the video
Well done Dan, you make it look so easy 👍🏻
It not always is😂
Subbed. This is an insane amount of diagnosis that the majority of mechanics wouldn't do. Im so glad my toyota/lexus dont have these issues lol.
I honestly don't know much about cars, but it was very easy to understand your explanations and to follow through. thank you 👍
That was sweet,it looks very easy to fix cars when when Dan is on it. Great teacher ever. Thanks
Wow thanks!
I have to admit, I'm impressed. My first thought was "it's a Mercedes, good luck with that.
you are so amazing , keep up your good work !!!! electrical problems are not easy to fix .
Thanks!😊
Great job Dan!! Thank you for sharing the video!!
My pleasure
