Their range of specialist diesel diagnostic equipment gives our technicians the ability to interrogate the vehicle’s electronic and mechanical systems quickly and efficiently.

Common Rail Injection Testing & Bench Repair

Our Diesel repair workshops are able to bench test a variety of common rail diesel injectors. We are able to source parts as well for repairs on a variety of injectors Bosch, Delphi, Siemens and more.

Diesel Pump and Injector Bench Test and Repair

Given the high pressures and fine tolerances inherent in today’s fuel injection technology, component cleanliness is of the utmost importance. Through our partnership with Delphi we have purpose built a "Clean room” designed to ensure the highest standards of cleanliness during the testing and repair. The clean room’s “state of the art" cleaning equipment supplied by Hartridge is ideal for both injectors and pumps, providing a rapid cleaning cycle for the removal of impacted dirt.  Accessing genuine Delphi replacement components is key to reinstating the precision performance of injectors and pumps.
