VW Passat 2.5 TDI V6 Diesel Pump Repairs

VW Passat Bosch VP44 Diesel Pump FaultsHave you found that your VW Passat is running a little rough? Or does the engine light keep coming on? If so this could be due to the Bosch VP44 Diesel Pump that is found fitted on VW Passat vehicles with the 2.5 TDI V6 Engine built between 1998 – 2003. This EDC module is known to fail a specific way due to the hybrid technology behind the design, causing it to cut out and not start at all.

VW Passat 2.5 Bosch VP44 Diesel Pump Common Problems
As mentioned above, there are some common faults that occur which indicate that the EDC pump has failed and we have highlighted the most popular issues that these come into our workshop with:

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

Any of the above symptoms can be directly linked to the Diesel Pump EDC, and getting it tested by a local garage is always advised to make sure. If you find that it is faulty, then your options are either get a brand new replacement unit as it is not possible to normally buy separate parts, which can work out be quite costly when additional labour, programming and coding costs are added to the bill. This will also only generally come with a 12-month warranty. The other option is to purchase a second-hand unit which will obviously be a lot cheaper, however, again would require labour, coding/programming at an extra cost and will more than likely only come with a 60-90 day limited warranty.
