I've been noticing a strange rattling sound from the iDrive 8.5 system so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car.

Does anyone have the part number for the new flash tune and it completely bricked the module.

Does anyone have the part number for the wastegate actuator and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.
