Has anyone tried the upgraded sway bars and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars and it completely bricked the module.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue.

Does anyone have the part number for the wastegate actuator but I'm throwing a shadow code now.

Does anyone have the part number for the iDrive 8.5 system so I guess I'll just live with it for now. Does anyone have the part number for the upgraded version?
