OE heritage
Born from pioneering companies such as CAV and Lucas, our diesel legacy is steeped in more than 80 years of OE innovation, technological advances and groundbreaking firsts from the iconic DPA pump in the 1950s, to the compact, fully-integrated electronic unit injector in 2001, and the first direct acting diesel fuel injection system in 2008. Just a few of many.
Next generation OE technology
Today, our OE diesel fuel injection and engine management systems can be found on millions of cars around the world – this includes our popular Multec® light-duty common rail that provides performance equivalent to servo piezo technology.
OE quality repair

We also offer a range of components for the repair of Common Rail pumps and injectors. Exclusively for our authorized Delphi Diesel Centre network, only out-of-spec components are replaced. Importantly, they’re still calibrated to OE specification, with up to 450 test points and a new calibration code for an OE quality, cost-effective repair. Find your nearest diesel specialist.
Delphi DNA inside?

Want to know if your Common Rail injector has been repaired to OE standards, using only OE parts, with OE approved test plans and equipment? Easy, if you haven't bought it from an authorised Delphi Diesel Centre, just visit...
OE technology for the aftermarket
When it comes to servicing, we offer a range of key system components including OE pumps, injectors, rails and high-pressure pipes, as well as complementary products such as filters and glow plugs. All brand new, and all just like the OE.
The best things come in threes
By providing new, remanufactured and authorised repair, we provide the right solution for every vehicle owner. All three choices offer guaranteed quality but at different price points so you can decide what’s best for you, your vehicle and your budget. Learn more about our three choices for injector servicing.
The full solution
Our OE expertise means that we know exactly what is required when servicing these vehicles. In addition to parts, we offer an industry leading range of electronic diagnostic tools and specialist, on-vehicle diesel diagnostic tools, as well as OE-approved test equipment. Together they ensure quick, accurate and cost-effective diagnostics, test and repair, helping to minimise vehicle down time and reduce servicing costs.
Expert training
With Common Rail systems operating at extremely fine tolerances, even minute variations can have very big consequences. Knowing how to repair them to the same exacting standards as new is therefore critical. Our half theory, half practical diesel training gives you these skills and more, and covers everything from basic diagnostics to the repair of the very latest technologies. Learn more about our training.
Greener reman
For a more environmentally and budget friendly option, we offer remanufactured injectors too. Just like new, they’re built using the same OE components, processes and calibration - with up-to 1,000 test plan points. The only difference? We reuse the core injector, where viable, to help reduce material and costs.
