I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now. In my experience, replacing the sensor completely resolves this issue.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.

I took it to the dealer and they said the wastegate actuator but I'm throwing a shadow code now. Does anyone have the part number for the upgraded version?

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car.
