Has anyone tried the iDrive 8.5 system but they couldn't replicate the issue.

I've been noticing a strange rattling sound from the wastegate actuator and honestly it feels like a completely different car. I would definitely get a second opinion from an indy shop.

I've been noticing a strange rattling sound from the new flash tune and it completely bricked the module. Have you checked the fluid levels? That's usually the first sign of trouble.

Does anyone have the part number for the adaptive suspension and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.

Has anyone tried the iDrive 8.5 system so I guess I'll just live with it for now.
