I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car. Does anyone have the part number for the upgraded version?

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

Has anyone tried the new flash tune 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 took it to the dealer and they said 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.
