BMW 320D / 520D 2.0D Diesel Pump EDC Repairs

BMW 320D / 520D 2.0D Diesel Pump EDC Repairs
The BMW 320D and 520D manufactured between 1998 – 2003 come fitted with the common failing Bosch VP44 (PSG5) diesel pump. This type of diesel pump has the diesel pump ECU / EDC (Electronic Diesel Control Unit) fitted to the top of the hydrualic/mechanical pump and is a very common failing part.

There are many faults associated to a failed EDC unit but below are some of the most common faults we’ve seen on failing EDC units, including the vehicle not starting:

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

When the Diesel Pump Control Module fails your dealer may advise that the units cannot be repaired and recommend replacing the Diesel Pump + EDC module complete. The cost of a new replacement part can be very expensive, will only come with a 12 month warranty and will require coding to the vehicle. Used second-hand parts are not recommended as the used part may also become faulty in the near future, come with a limited 30-90 day warranty and may require re-programming.
