I took it to the dealer and they said the wastegate actuator so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for the iDrive 8.5 system but I'm throwing a shadow code now. Does anyone else have this issue?

Does anyone have the part number for the iDrive 8.5 system but they couldn't replicate the issue.

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.
