Our modern warehouse facility in central Lancashire holds vast stocks of OE and quality diesel fuel injection spares parts with next day delivery, Diesel injector nozzles, Fuel lift pumps, Injector pipes, Fuel Filters, Fuel primers and stop solenoids, covering most diesel fuel injection systems.

In 1998 we realised the enormous impact Common Rail would have on the automotive industry and immediately started a development programme to enable Darwen Diesels to provide a comprehensive ALL MAKES diesel Common Rail test and repair service to the aftermarket.

Since that time we offer our customers a full range of Test Benches, Testing equipment, Specialist tools, Replacement Parts, Updates and the "know-how" to fully Test and repair Common Rail Injectors and Pumps by Bosch, Delphi, Denso and Siemens VDO Solenoid and Piezo, EUI, PDE, PPD.

Darwen Diesels has established a Common Rail Diesel Repair Centre Network of 40 plus fully equipped Diesel Common Rail System Repairers using this equipment, situated throughout the UK, Ireland and the Channel Islands.

We offer a comprehensive range of 'in house' remanufactured Common Rail, EUI, PDE and PPD Injectors and pumps on an Exchange or Customer repair program basis for a wide range of cars and light commercial vehicles.

Darwen Diesels are also UK distributors for:

  • Firad - Diesel Injector Nozzle

  • Corona - Diesel Test Equipment

We also offer a relatively new addition to our product and service portfolio - DPF Cleaning Services. Where as previously, DPFs which has become ineffective were scrapped or replaced, using this service they can be regenerated. This has considerable environmental and cost benefits.
