I had an annoying rattle from the dash from day 1, and I was certain it was something behind the screen. Turned out it was the interior rear view mirror/rain sensor housing that was rattling because the sound actuator was vibrating the windscreen, which in turn was vibrating the rear view mirror housing. The problem happens only during acceleration and stops when I held the mirror down.
It has stopped now but if it does come back, the plan is to wedge some rubber foam between the housing and the windscreen.
