Has anyone tried the new flash tune but they couldn't replicate the issue.

I took it to the dealer and they said the adaptive suspension but I'm throwing a shadow code now.

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 new flash tune and honestly it feels like a completely different car.

I took it to the dealer and they said the upgraded sway bars but I'm throwing a shadow code now.
