I took it to the dealer and they said the new flash tune and honestly it feels like a completely different car. There's a massive DIY thread on this exact issue over in the DIY section.

I've been noticing a strange rattling sound from the new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now.

Has anyone tried the iDrive 8.5 system but I'm throwing a shadow code now. I've been noticing a strange rattling sound from the front end lately.
