im writing this post on behalf of my friend.he has got a tdi110 which has developed a really irritating sound. it sounds like something rattling sound coming from the timing belt of the engine almost like a bearing sound. it starts at about 1750rpm and goes away at about 2000rpm. any ideas of what it could be?nothing seems loose or anything and i cant feel any leaks or anything. oh also its only when the car is moving along in gear it doesnt happen if its revved with no load on
