No Bluetooth Audio after MGU replacement
Hi guys,

We had a MGU replacement in G07. Donor unit was patched and loaded new fsc and coded for car.

Sound works ok from FM stations but not from mobile bluetooth. (carplay connects)

Is it something related to coding? Thanks

hi, check the errors in the head unit, maybe your bluetooth chip is not working.
The corresponding error will be logged.

check error code: B7F8BB internal control unit (Bluetooth chip)

Does that line also affect the Radio FM sound?

No any other clue guys?

In addition of Audio bluetooth, noticed that even usb is not working. Is it something related to hardware or software?

Thanks
