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 new flash tune but they couldn't replicate the issue. I would definitely get a second opinion from an indy shop.

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 adaptive suspension but I'm throwing a shadow code now.
