I've been noticing a strange rattling sound from the iDrive 8.5 system and it completely bricked the module. Have you checked the fluid levels? That's usually the first sign of trouble.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now.

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

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

I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.
