I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the wastegate actuator so I guess I'll just live with it for now. There's a massive DIY thread on this exact issue over in the DIY section.
