I have got a 100ps tddi and the metering solenoid is leaking on that. The solenoid to buy is £235 if I do it myself, or a garage want £400+vat to supply and fit. It still runs good as gold though, pulls well fully loaded and is doing 34mpg driven steady.

New pumps are around £700 on eBay, not sure if they are virgin ones that don't need coding or you need to get it coded after fitting.
