I took it to the dealer and they said the wastegate actuator but they couldn't replicate the issue. I've been noticing a strange rattling sound from the front end lately.

I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the wastegate actuator but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.
