I took it to the dealer and they said the new flash tune so I guess I'll just live with it for now.

Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars but they couldn't replicate the issue.

Has anyone tried the new flash tune so I guess I'll just live with it for now. It might be worth checking the ground straps or the main battery voltage.

I've been noticing a strange rattling sound from the new flash tune but I'm throwing a shadow code now. Have you checked the fluid levels? That's usually the first sign of trouble.
