I took it to the dealer and they said the wastegate actuator and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune so I guess I'll just live with it for 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 but they couldn't replicate the issue.

Has anyone tried the wastegate actuator and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.
