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

I've been noticing a strange rattling sound from the iDrive 8.5 system 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 adaptive suspension and it completely bricked the module.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now.
