I posted earlier about my 03 turbo noise and this may show how stupid I am, but I did not even know the "spoiler" went up and down until recently and that is the noise I was hearing. I bought the car used from a chevy dealer with no manual and just liked the VW forever without any experience with one. The spoiler however makes so much noise that passengers that havent ridden in it always ask What is that noise and they think i have something slamming around the trunk. That is the question i have and is that a normal sound? Thank you!!!!!!
