So I have a 1 month old GTI S with about 2500 miles on it. From around mile 200 or so, Ive noticed this rattle that sounds like its coming from either behind the driver side dash or under the drivers seat. It only happens at highway speeds and appears worse in colder weather with significant headwind. Ive looked under the hood and could not find anything obviously loose. For a little while, it seemed that adjusting my seat by lifting it up solved the issue, but the rattle has returned. Any ideas? Its completely stock and is otherwise working flawlessly!
