I have heard a story or two that the PD diesel whether it be in 115,
130 or 150 bhp form have had problems and some engines have had to be
replaced [:O]

so in other words is this true and these engines are unreliable or just a myth?

there was believed to be a problem with the high operating pressure of the injectors contributing to premature bore wear  on PD 130s although as the 100, 115 and 150s use the same injection system I don't know how they reckon 130s suffer and don't mention the others

A lot of engines ended up needing replacement because the wrong oil was used in them. The PD engines are very sensitive to oil type and the wrong one can kill the engine very quickly. It was probably due to confusion over the Extended service intervals and VSI. Apparently cost VW around ?50 million.
