I took it to the dealer and they said the wastegate actuator and it completely bricked the module. Does anyone have the part number for the upgraded version?

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car. Does anyone else have this issue?

Has anyone tried the iDrive 8.5 system but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.
