Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now.

I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

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

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. I've been noticing a strange rattling sound from the front end lately.
