At first mine sounded like the rattling was coming from the dashboard. But after some time, it sounded more like the passenger door. Lately though, it sounds like the driver door too. So I took it in last week and the dealership told me that it was actually the sunroof making all that racket (I have the panoramic roof). So they said that they didn't have the "stuff" (lack of a better way of saying it because it was so noisy in the service department, that I didn't get the name of the "stuff") so I'm bringing it back in Monday so they can take care of it... So we'll see what happens.
