Bosch VP44 (PSG5) Diesel Pump EDC Repairs

Bosch VP44 Diesel Pump EDC Repairs
The Bosch VP44 Diesel Pump (PSG5) is fitted to a wide range of vehicles and is a very common failing part. Due to the Hybrid technology behind the design of the Bosch VP44 Diesel Pump we have found the unit will fail in very specific ways which will make the vehicle cut out and not start.

Bosch VP44 Diesel Pump Testing
We are taking these units in daily to be tested and repaired. On testing these units we have found that the fault is within the Electronic Diesel Control Unit (EDC) and not the mechanical part of the diesel pump. Our latest diesel pump test rig allows us to communicate directly with the EDC unit and test all functions of the electronic diesel pump. Our extensive soak testing will not only flag up the most common faults but also highlight any intermittent faults.

Our Bosch VP44 Diesel Pump EDC Repair Service
When carrying out a Bosch VP44 Diesel Pump Repair, we use new genuine OEM components and also uprate the components which trigger the failure to ensure that each and every Bosch VP44 diesel pump is rebuilt to meet & exceed OE specifications. We also carry some common failing part numbers on the shelf, rebuilt and ready for exchange.

Our current turnaround time for diesel pump repairs is 3-5 working days and no programming is required when the unit is returned to you, making it plug & play. All Bosch VP44 Diesel Pump rebuilds come with our Lifetime warranty.

Because the Bosch VP44 diesel pump is fitted to such a wide range of vehicles, the fault codes may vary but will all point back to a failed electronic diesel control unit (EDC). Below are some common fault codes we’ve seen units come in with.

VAG Codes: 00550 / 00628 / 01268 / 01318
Other Fault Codes: P0190 / P1220 / P1335 / P1551 / P1560 / P1561 / P1600 / P1630 / P1631 / P1651 / P1660 / P1661

When these fault codes occur, you are normally advised by dealers and local garages that the unit will require replacing and depending on the vehicle it can cost upwards of £1000 with labour & programming. Our diesel pump repair service is fast, efficient and affordable and we are able to repair these units providing they have not been tampered with.

Note: The hybrid technology within the EDC is very easily damaged and should only be opened by a skilled professional with experience in hybrid EDC repairs.

Removing and fitting of the Bosch VP44 diesel pump can be a very involved job and we do offer professional fitting services if required.
