Pump-nozzle problem in TDI engines

  • Damage to the injector seats in TDI engines due to sideways tilting of the holding shoes.
  • Cause: One-sided screwing of the holding shoes leads to uneven pressure on the injector seats in the cylinder head, which causes run-in marks.
  • The WFR pump-nozzle solutions offer an effective, uniform fixation for the pump injector injectors.

Which engines are affected?

All VWAG TDI engines from 1998 - 2010 with a pump injector unit are affected. The following brands are affected: Audi, Seat, Skoda and VW.
