This is a factory recall to prevent the possibility of boiling hot water being 'spewed' over your feet. It is not optional. I have spoken to Volkswagen on this very topic only a matter of a few weeks ago (as a result of a previous question on this point on this very forum). Volkswagen have maintained a list of cars that have been modified and they perform this modification to any car that requires it regardless of the age or the mileage of the car. It is not a replacement of a faulty part - it is the fitting of a safety bypass device. It is not for your local dealer to say that VW have stopped doing it - they have not. It sounds as though your local dealer is being very lazy and can't be bothered. Go and see them again, ask them to check if the modification has been performed and if not instruct them to carry it out. If they refuse, take it up with VW HQ in Milton Keynes, their number is in the phonebook. regards, yt.
