Diesel filter on JTD engines is changed every 12000 miles or annually whichever comes first. It is an industry standard that fuel filters are drained every 6000 miles or 6 months, check most service books and you will find it. Citroen, Peugeot, Mitsubishi, Rover etc. Very few cars actually have it done, lease companies wont pay for it to be done either so its left to techs to do it on their own cars and anyone else who finds out about it.
