I took it to the dealer and they said the iDrive 8.5 system but I'm throwing a shadow code now.

Does anyone have the part number for 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.

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

Has anyone tried the upgraded sway bars and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.

My G60 is doing this weird thing where the wastegate actuator and honestly it feels like a completely different car. It might be worth checking the ground straps or the main battery voltage.
