Driver Side Heated Mirror not working
Hey guys need your input on this please.
So for over a year now, my driver side heated wing mirror hasn't been working. VCDS reveals the following error message: Address 42: Door Elect, Driver Labels: 4E1-910-802-42.lbl Part No SW: 4E1 910 802 B HW: 4E2 959 802 F Component: Türsteuer.FS BRM005 0180 Coding: 0028462 Shop #: WSC 02313 785 00200 VCID: 20486A13F3B91341C9-8074 1 Fault Found: 00920 - Heated Outside Mirrors; Driver Side (Z4) / Passenger Side (Z5) 012 - Electrical Fault in Circuit - Intermittent Freeze Frame: Fault Status: 00101100 Fault Priority: 3 Fault Frequency: 0 Reset counter: 233 Mileage: 138176 km Time Indication: 0 Date: 2017.06.28 Time: 23:35:28 I have run several diagnostics and it has costed me quite a bit. I was able to source a replacement mirror on ebay same as the original but that didn't fix the issue. Next I checked the wiring between the mirror and the door control module ecu, and that seems fine as there is continuity running thru the wires after checking with a multimeter. And lastly, I replaced the door control module with a replacement but unfortunately that still didn't fix the issue. Can anyone shed some light on this please. The Passenger side heated mirror works fine.

According to the wiring diagram, It's the door control module that controls the heated function so i can't think of any other wiring between the ECU and the mirror to be at fault.

If you end up with a spare heated drivers side mirror glass that is surplus I'd be interested as I've got one on the way out on my D3 daily - although mine is a round fog lamp D3 single grille model so not sure that the mirror glass is the same??

I have replaced the glass with a new one because the auto dim was discoloured and I assumed the heater element had failed. I've since checked the element in the old glass and found that it is OK.
I will have to check the cables for continuity but to do that I'll have to drop the door card. Not done that yet so will have to read up how to do it. I do have a spare mirror mount complete with cables so if I have a cable problem I should be OK. After that it could only be the controller.

The only issue i can think of now is a wiring problem in the wing mirror harness as my Side Assist light on that side is also having an issue.. Might be a grounding problem. I will next try to remove the Side Assist light and check if that's the culprit itself.
