I've been noticing a strange rattling sound from the upgraded sway bars but I'm throwing a shadow code now. 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 and it completely bricked the module.

I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car.
