On the VW TDIs, the HPFP is prone to self-destruct and pollute the entire fuel system with metal shavings from the worn cam+roller assembly. Discussions online say poor diesel quality in the US was a contributing factor. It was never fixed and only a extended warranty was offered.
That isn't the whole story. If you read the government website that reports on proposed recalls and investigations, around 90% (going off memory here) of the TDI failures were tracked to miss-fuelings by the owner with gasoline. That's the reason that no redress was offered.

All BMW diesels in the USA/CA have miss-fueling interlocks to prevent that, and there have been few cases of HPFP failures that trash fuel systems.
