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:
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.
We are able to fully test and rebuild all Bosch VP44 Diesel Pump Controller (EDC) units. We use new genuine OEM components when repairing the EDC unit to ensure that each and every rebuilt EDC unit meets & exceeds OE specifications. All of our rebuilt EDC’s come with a Lifetime warranty and will not require coding back to your vehicle.
Note: The Bosch VP44 Electronic Diesel Control unit uses hybrid technology and can be damaged very easily so it is advised NOT to try a DIY repair. These units should only be opened by experienced specialists with extensive knowledge in hybrid EDC technology.
Removing the EDC unit can be very involved and we do offer a professional fitting service at our Diesel Pump Repair Workshop if required.
