Problem:
Bcm2 problems on a 2014 Audi A4, anyone have suggestions? Read on bench with xhorse vvdi prog, car is dead now. Anyone have a repair service I can use?
I have read and verified dflash and pflash before reinstalling in car.

Possible reasons:
To read encrypted BCM you need remove the resistor components before reading.
The components are not soldered back on properly.
Solutions:
1. Get donor and write files to it and you are good to go. Everything will be fine.
2. Send the car to someone who have odis with a used BCM. It takes less than 24 hours to get the approval from ingolstadt and get it programmed. Just fixed one the other day.
3. After brick a same bcm2 on Audi A7 restored with hextag/hexprog with original backup of eeprom and donor A6 backup of flash, recoded and updated via vagcan pro, all was ok and car was gone, if you have hextag/hexprog can help with restore of this unit.
