I asked my dealer that very question when my clutch was being replaced last year and he said according to VW it needs changing at 130k or 9 years, he went on to say that by then I would probably have gotten a new vehicle so it should not be an issue, however, if I was going to keep the van long term (which I am) I should forget the reccomended milage/interval and do it at 70k or 5 years.
