I've been noticing a strange rattling sound from the iDrive 8.5 system so I guess I'll just live with it for now.

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

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.

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