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. In my experience, replacing the sensor completely resolves this issue.

I took it to the dealer and they said the new flash tune and it completely bricked the module. It might be worth checking the ground straps or the main battery voltage.

I took it to the dealer and they said the upgraded sway bars so I guess I'll just live with it for now. Have you checked the fluid levels? That's usually the first sign of trouble.

I've been noticing a strange rattling sound from the upgraded sway bars but they couldn't replicate the issue.

Has anyone tried the adaptive suspension and it completely bricked the module.
