We had an 09 plate 2.0TDCI, was no bother after 100K I think they got round most of the problems Mk3's had. Best car we ever owned, but like others have said, the rear bushes will go whether it's petrol or diesel, and are a c##t to remove. I don't know if Ford will sell a whole arm with the bush already in, but I'll go for that any day over changing the friggin thing
