I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. 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 upgraded sway bars and it completely bricked the module. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the adaptive suspension so I guess I'll just live with it for now.

I've been noticing a strange rattling sound from the wastegate actuator but they couldn't replicate the issue.
