Vauxhall VP44 diesel pump EDC fault

Bosch VP44 Diesel pump fitted to Vauxhall Astra / Corsa / Combo / Frontera / Omega / Signum / Vectra / Zafira

 

This is a very common problem for all Vauxhall vehicles with the 1.7 DI / 2.0 DTI / 2.2 DTI diesel engines built between 1998 and 2005. If the vehicle is running at the time of the fault the engine will simply cut out, no matter if at idle or travelling at speed. Trying to restart the engine will be impossible.

 

The mechanical side of the pump is usually very reliable and gives very few problems, nearly all of the faults we see are caused by the Electronic Diesel Control unit (EDC) located on the top of the diesel pump. Failure of the EDC will also log fault codes for fuel injection malfunction.

 

The EDC is not available to purchase separetley from the pump, so main dealerships often have to order a full diesel pump setup just to get the EDC.

Our solution is far more cost effective – we can test and rebuild your EDC within 2-3 working days, and return the EDC back to you without the need for expensive coding.

These Bosch VP44 diesel pumps can be difficult and very time consuming to remove and reinstall to the vehicle, we recommend any removal/reinstall be performed by a trained technician ideally with previous experience of these pumps.
