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

Has anyone tried the iDrive 8.5 system and honestly it feels like a completely different car.

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

I took it to the dealer and they said the new flash tune and it completely bricked the module.

Does anyone have the part number for the wastegate actuator and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.
