diesel_pump_vp44_6cyl_small
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.

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.

Please note that we only test the EDC on top of the pump, we cannott test the mechanical part of the pump.

We are now repairing customers own Bosch VP44 diesel pump control units and providing a Lifetime warranty*

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. Attempting to run these pumps when they are drained of fuel can seriously damage the mechanical side of the pump.
