Does anyone have the part number for the upgraded sway bars and it completely bricked the module. Does anyone else have this issue?

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

I took it to the dealer and they said the iDrive 8.5 system so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.
