My injector pump on 2007 dci has died taking with it the common rail & all injectors!!!! Dealer quote to repair was over 5 grand, ouch!!! but after finding a reconditioning plant did it myself for 2 grand, better. Aparently the delphi pump with reff no., starting 9042A........ is the problem. over 50 thou miles it wears out putting swarf through the system by way of the return flow to the fuel tank!!!! the good news is that the later generation pump ref no., 9424A......... is OK. Has anyone else had the same?

Do believe fuel pump failure is fairly common with modern diesels.
The bosch pumps are no better, although it is usually the integrated electronics that fail first, and only a new pump @ around £3000 is required.

The latest scapegoat is biodiesel.

The belief is that biodiesel does not lubricate the pump like proper mineral diesel does. This is supported by the latest generation of pumps using teflon in their construction. The workaround adopted by most forum boys is to add mineral 2stroke oil to the fuel tank as a lubricant.

Modern diesels are turning out to be moneypits with pump failures, particulate filters, that magic liquid that costs £300 a litre, to the point that it is only people who can put 30,000 miles a year on them who buy them, and they get rid as the warranty expires.

The real get-out clause for the manufacturer, is no matter what happens, they just claim the vehicle was miss-fuelled at some point in its life and this is what damaged the pump.
