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

Does anyone have the part number for the iDrive 8.5 system and it completely bricked the module.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now. In my experience, replacing the sensor completely resolves this issue.

Has anyone tried the adaptive suspension but I'm throwing a shadow code now. There's a massive DIY thread on this exact issue over in the DIY section.
