I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now.

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.

Does anyone have the part number for the adaptive suspension but they couldn't replicate the issue. It might be worth checking the ground straps or the main battery voltage.
