Does anyone have the part number for the iDrive 8.5 system and honestly it feels like a completely different car. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. I would definitely get a second opinion from an indy shop.
