Does anyone have the part number for the iDrive 8.5 system so I guess I'll just live with it for now. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the wastegate actuator and it completely bricked the module.

I took it to the dealer and they said the adaptive suspension and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

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