I've been noticing a strange rattling sound from the iDrive 8.5 system and honestly it feels like a completely different car.

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

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

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 front end lately.

Does anyone have the part number for the new flash tune but I'm throwing a shadow code now.
