Ford Fiesta / Focus / Mondeo Diesel Pump EDC Repairs
The Bosch VP44 (PSG5) Diesel Pump is a very common failing part and found fitted to a variety of vehicles including the Ford range of Fiesta, Focus and Mondeo’s manufactured between 2000 and 2005. This particular design has the Diesel Pump ECU / EDC (Electronic Diesel Control Unit) mounted to the top of the hydraulic / mechanical diesel pump unit.

Inside the EDC Bosch is using hybrid technology to control the pressure and flow of the diesel pump but with it being mounted to the top of the mechanical unit it is subjected to heat and vibration which are too common known causes of premature failure for internal components.

Common EDC Failure Problems / Symptoms
The EDC can fail in many ways and the fault symptoms can vary quite a bit from having just the engine light illuminated on the dashboard to breaking down and having a complete non-starter. Below we’ve listed some of the common faults we’ve seen from customers sending EDC units in for repair.

• Struggling to Start
• Non-Starter
• Engine Light On
• Loss of Power
• Running Rough
• Stored Fault Codes

If your Diesel Pump EDC has failed then your local dealer will probably be quoting you for a very expensive replacement of the complete unit with additional costs for labour and coding / programming. This is because the EDC unit is not available to purchase as a separate part to the Diesel Pump. The new replacement part will require coding and will only come with a limited 12 month warranty. The alternative option would be to replace your diesel pump with a second-hand used part for much less but the unit will come with a limited 30-90 day warranty and also require coding / programming.
