Has anyone tried 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.

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.

I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now.

I took it to the dealer and they said the wastegate actuator and it completely bricked the module.

Does anyone have the part number for the iDrive 8.5 system but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

Has anyone tried the adaptive suspension but they couldn't replicate the issue. There's a massive DIY thread on this exact issue over in the DIY section.

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