The rattles come from the inside. The songs listed have must have a frequency that that rattles the car really bad. I have owned 3 bmws and nothing has ever been this bad. The dealer said it was the worst he has heard in a while. The weird thing is it is not the bass, it is the mids causing the issues.
Also the dealer claims the issues is with all F30s with HK systems.
