Fisrt my MMi stop working, after checking and cleaning with electro clean all connections behind glove compartment
Now noting is working did VCDS scan nothing is found not even Vin is reading
It looks like the modules can not communicate with the Bus. Did the Optical test and all OK
First it start and goes dead but now nothing. Checked all fuses .
I`m out of ideas for solutions

If you did the Optical Bus test, then it sounds like the Gateway is alive and talking. In that case, please post an Auto-Scan so we can see what else talks and what doens't.

I have not studied the wiring diagrams for this car, so I have no real opinion here.

Today did some power measurements on console Control Module for Display and Input; Front (J523) and found power on it
Also there are power on CD changer (loads cds), DVD (load dvds), MMI, Radio unit in luggage compartment
I am thinking that Control unit for front display and information control panel - J523 is the problem
How to reach this seen that I removed the glove compartment and found only MMI display, Gateway bus, Control Module for Headlight Range (J431) t, and a power supply control unit

Need some help here pls
