Hi
I would like to start by saying that when I started this video, I was planning to resolve two issues in the same video; but later I have realized that the issue with the door controls would make on its own a video long enough...
So, at the start, there is perhaps not so interesting stuff, even though we started to diagnose the door problem...
If you don't want to go through all of it, jump to minute 15:40... just to mention, that before that I went through the scan and live data that helped to guide me in the right direction.
That said, this car came to me with the driver door controls inoperational... not a single button would work!
Follow me on this video to find out what was the cause and how I got it resolved!
Hope you enjoy the video.
Any comments or questions please put them below.
Like always, thank you for watching!

This video was a TREMENDOUS help. I believe I have the same issue with my 2010 E350. None of the controls in my passenger door work, but I can control everything with my bi-directional OBD2 scanner. Thanks for being so meticulous!!

Submodules connect to modules which conect to another modules that go to module that ends to another modules... Actually it's not that difficult when logic aplied. By elimination you isolate the problem in this case, as in many cases. That's what diagnostician's job is, right? Thank you for another great module, I mean video ;)

@LMAutoRepairs 2 года назад

Check communications st the module... if communications are there, power and grounds, then perhaps you have a bad module... 👍👍👍

@michaellam4492 2 года назад

@@LMAutoRepairs Thank you for feed back…btw can you show me where is communication module locate Thanks

@LMAutoRepairs 2 года назад

Irrelevant for now... What I meant is, on the door module, check that you have communications... scope the communication lines... Then, check that there is power and grounds at the module... If everything is there, then there is a good chance that the module is bad... If any is missing, you need to trace it back... Hope it makes sense...

Air suspension the shocks all read red figures in live data. The suspension lowered rear right and then left to match it. rear level sensor says 121mm regardless of if its dropped or not. Where would you be thinking to start in trying to fix this. Clearly not all sensors failed same time. So unless power feed to all sensors is reduced and they do share the same feed, then I would be thinking module faulty. Await your thoughts.

@LMAutoRepairs Год назад

Your thought makes sense... sounds like one comom issue causing that... But you need to do your own checks... check diagrams to see what all the sensors have in common etc... 👍👍👍

@jamesbarratt593 Год назад

@@LMAutoRepairs yep its w221 year 2007. Half an idea to remove lines to wheels and fit tyre valves to them. Fill the shocks from air line and monitor by tape measure above tyres so they all same. Then pulling airmatic fuse and be done with it. Half a mind. We shall see. Cheaper alternative.

Hi Great video. I have same issue, the driver window only wouldn't go down, seems to be the door control module. My original unit number is A003 820 7926. I cannot buy exactly the same, can I buy any control unit for front driver side of mercedes w221 between 2005 - 2009 or do I need to find exactly the same number? On my launch diagnostic it shows window not normalized now. I hope to be able to reprogram the new one if it is different number would that be possible? Many thanks, amazing video!
