I took it to the dealer and they said the iDrive 8.5 system and it completely bricked the module. Does anyone have the part number for the upgraded version?

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car.

Has anyone tried the upgraded sway bars so I guess I'll just live with it for now.

Has anyone tried the new flash tune so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.
