On the newer ones the high pressure fuel pump disintegrates and poops metal bits into the engine, requiring the engine to be replaced. That's why VW recently extended the warranty against the HPFP to, if I recall correctly, 100k miles.

- durin42 11y agoNote that the pump in question has been redesigned multiple times by Bosch. Hardware bugs are a thing, even in cars.
