Bosch VP44 (PSG5) Diesel Pump ProblemsAudi A4 / A6 / A8 2.5TDi V6 Diesel Pump EDC Repairs
VAG group vehicles, specifically the Audi A4, Audi A6 and the Audi A8 2.5 TDi V6 manufactured between 1997 – 2003 come fitted with the common failing Bosch VP44 (PSG5) diesel pump. The mechanical part of this diesel pump is generally very reliable but the Electronic Diesel Control (EDC) unit which is mounted on top of the diesel pump is a very common failing part.

When the EDC unit fails, the most common fault is the vehicle not starting but you may notice some of the symptoms as below:

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