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

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

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 wastegate actuator but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the iDrive 8.5 system and honestly it feels like a completely different car.

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 wastegate actuator and honestly it feels like a completely different car.
