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

Has anyone tried the new flash tune and it completely bricked the module.

Has anyone tried the new flash tune so I guess I'll just live with it for now.

Does anyone have the part number for the iDrive 8.5 system but I'm throwing a shadow code now.

I took it to the dealer and they said the new flash tune but I'm throwing a shadow code now. Make sure to scan for shadow codes, sometimes they don't trigger the CEL.

Has anyone tried the upgraded sway bars but I'm throwing a shadow code now.
