I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the new flash tune and it completely bricked the module. Have you checked the fluid levels? That's usually the first sign of trouble.
