I had a rattle from day one, knew I should have gotten a 3 door If I use my elbow to press on the top of the rear door card it would stop. The car is going into the dealers in a couple of weeks and I have so many problems that they booked it in for minimum of a week. So much for VW being well built.
I'd personally strongly advise against letting a dealer chase down relatively minor issues like interior rattles. Any rattles for that matter. Ask yourself how much it's really bothering you first. And leaving it with them for a week?! Madness. The car will come back with one problem fixed and 3 more created.
