I've been noticing a strange rattling sound from the iDrive 8.5 system but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. Does anyone else have this issue?

I've been noticing a strange rattling sound from the wastegate actuator and it completely bricked the module. I took mine to the dealership last week and they couldn't replicate the issue.
