I believe my rear door Modules somehow became corrupted while coding using OBDEleven. Even do I was not coding the doors. Looking for someone with VCDS experience in the San Antonio TX area that can help me out figured it out what the heck happen?

I am surprised that this would get corrupted by changing something other than the module itself unless something shorted or you interagated the control module and unknowingly changed something. Did you do a scan of the rear modules?

I was unlocking via OBDEleven the Ambient lights Menu on the MMI to activate the foot well lights. I did all the activation reset the MMI menu appear.

However my dimmer switch does not work anymore and my car is not getting any power to light the rear doors window switch. They windows go up and down but they don't have lights anymore...

I redo all I did again via OBDEleven reset the MMI. Still not working..

I remove the rear door panels check all the connections, the are good plugged properly to the Module. Still not red lights on rear window switch.
I have no idea how to fix this. Because everything should work fine since I reverted back the coding I did. And I double checked the history logs of what I did. I never touch the rear doors during the coding.

Scan the car..among other unknown codes I have this one

U020200 - Lost Communication With “Door Control Module D”

I use this thread. I did all the coding except the one in the doors because I did them already months ago.

Did you install lights? Why did you enable the menu?

[Eli0073]

Because I was doing the Foot well lights retrofit.

So the best thing to do, if you have not already done so, is to uninstall or disconnect all the lights you put in. Once you do this, return all the coding to how it was originally and reset the MMI. See if this works. If this does not work then when you installed the lights, I would assume that something shorted or loaded the circuit such that it damaged something.

[Eli0073]

I did that already...unwire the lights that are wired to the window switch and nothing. I also when back to the original rear door long codes and cycle the doors and even disconnect the battery of the car and still nothing.

I'm getting this codes..
