Door Module 42 - Error Code U10BA00

I'm having same issue. All do I was doing something different when it happens. Have you fixed it?

I was unlocking via OBDEleven the Ambient lights Menu on the MMI to activate the foot well lights as I was getting ready to do the retrofit. As I have previously done the necessary coding and done Puddle lights retrofit and ambient lights in the door buckets this one are wired to the door window switch.

I did all the activation reset the MMI and menu appear.

However two things happen, my dimmer switch on the dash does not work properly it doesn't lower the intensity during the day, only at night when the auto lights turn on, is when it works and my car is not getting any power to light the rear door window switch or the rear door ambient lights on the door buckets. The rear windows go up and down but they don't have lights anymore...

I revert all I did via OBDEleven reset the MMI. Still not working..
I remove the rear door panels check all the wiring connections, they are good and plugged properly to the Module no damage or pinch cables I also check the main door wiring that plugs to the chassis pillar. Still not red lights on rear window switch. I check all car fuses also good.

I have no idea how to fix this. When I was unlocking the ambient lights menu on the MMI, I never touch or code the rear or front doors because they were already coded. I'm really puzzle 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 then long coded the rear doors with the original code prior to unlock puddle lights and got nothing. I try the code from after the puddle lights, prior to this issue and still nothing. I have cycle the doors during the coding and even disconnect the battery and still nothing. I unplugged the leds lights from the rear window switch and still nothing.
