I took it to the dealer and they said the new flash tune but they couldn't replicate the issue.

Does anyone have the part number for 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 iDrive 8.5 system so I guess I'll just live with it for now.

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