2014 Mercedes E350 no communication with instrument cluster, no power steering CANBUS case study

Mate your video saved me loot of time searching for issue thank you!🙏

I've been struggling with this very issue myself for far too long, never in a million years would I have diagnosed the headlight for power steering and all the instrument cluster stuff, I figured it was ECU related. I can't thank you enough.

[@globalcommerce7654]

Glad to hear it helped. They make these car systems unnecessarily complicated causing owners major problems for silly issues.

@@globalcommerce7654 I appreciate your reply, if you don’t mind I’d love your input; today I’ve gotten my headlight assembly (full of water) out and disconnected, and just as you’d found, power steering and the instrument cluster are back up. I’ve got to drive this car out of town tomorrow if at all possible, but cannot get a new headlight assembly in time, and the problem headlight was/is partially functional but the low beams were out due to water inside the assembly and had been for a while before causing the power steering and instrument cluster issues. My question to you is, if I were to dry it out completely, maybe replace a bulb or 2 and the fuse in the back, and put it all back together, do you think it would work temporarily until I can get a new headlight in (about 3-7 days from now)?

@@LifeAintShitButAFatVagina I you don't mind driving without 1 headlight, you can remove the module under the light and leave the cable dangling, plug back headlight and everything else should work minus the low beam.

[@LifeAintShitButAFatVagina]

@@globalcommerce7654 just unplug that main connector behind the light and bolt everything back together and I should be straight? Or is there a module in the headlight assembly specifically for the low beam? Sorry to bother you with questions, been wrenching for awhile but electronics and wiring are not my area of expertise. Edit: Sorry, misread, I understand now, thank you again!

Have a question @globalcommerce7654

great video bro thank you for sharing your hard work

You are the best amigo

Great video. I'm trying to diagnose a parasitic draw on fuse #27 which is supposed to be for the ignition lock module and the Gateway Control Unit. I have been trying to find the Gateway Control Unit, would you happen to know where that is?

[@advancedleveldiagnostics]

Great video, Thanks! Would you mind moving your watermark to the bottom, it's a little distracting?

[@globalcommerce7654]

I keep it off center but in frame because believe it or not the Chinese started stealing my videos and using them without my permission..

[@suryaprihadi2258]

Always use MB OE wiring (ebay one ok, easy to get hacked ones MB WIS EPC ), not 3rd party re-drawn one. 2014 is a facelift version. CAN BUS is a bit different from pre-facelift.

[@chrismiller603]

Can you show where in the back of the light what piece to disconnect?

[@globalcommerce7654]

The main connector..

[@chrismiller603]

Also I did that and it restarted...but is there any other way to have my light working with the hi beam and the lo beam off with out the messages reappearing? I was at least driving with the hi beam at night, but can't now bc I unplugged it and don't want to risk getting pulled over at least until I get a new light

[@globalcommerce7654]

@@chrismiller603 it costs to be the boss.. you drive a mercedes that uses a computer to turn on a bulb vs a normal switch.. it comes with the territory.. you could always rewire hard lines to turn on bulbs but more effort than it's worth.

[@chrismiller603]

Lol yea you're right about that bro, it's just waiting for this light to be delivered, guess I'm just anxious to get it. Na, I'll just wait for the light and do it right, but thanks for the help and response greatly appreciated.

[@gtsmhyny1]

Did you disconnect headlight at rear of headlight?

[@globalcommerce7654]

Yes

[@kopykool5247]

Is there a way to disconnect headlights without removing the whole assembly? I’m currently having the same issue.

[@globalcommerce7654]

@@kopykool5247 I think on this car because of damage was able to reach under bumper to disconnect

[@kopykool5247]

@@globalcommerce7654 update: so I unplugged my headlight and everything is back to normal. Thanks bro.

[@kopykool5247]

Question, you have any website in mind or vendor that sells those headlights assembly for reasonable prices?

[@abuhamzahalmasry5627]

excellent work brother.lesson learned here ,don"t buy a european vehicle.they sre comfortable and fun to drive but very painful to fix and pay for repairs.any brand but german.their engineers have serious mental issues

[@globalcommerce7654]

I definitely wouldn't recommend buying these cars, lease for a year or 2 and get rid of them!👍🏾
