Rich OE legacy
Our heritage dates back to the legendary CAV brand, and the introduction of in-line and the iconic DPA pump – the best-selling rotary pump worldwide. Both were revolutionary for their time, setting new standards for reliability and power, and we’ve continued to push the boundaries ever since.
Three choices for fleets
By providing three choices – new, reman and repair – we can provide fleet managers with convenient service and maintenance at a very competitive cost.
Latest generation OE technology
Our latest generation F3 system takes engines beyond the 2021 global emissions and fuel economy regulations and through the next decade. Based on our proven Euro VI Common Rail technology and capable of 3,000 bar injection pressure, it delivers a substantial improvement in emissions, fuel economy and refinement for the lifetime of the engine.
OE-approved repair
In addition to new and remanufactured units, we also offer authorised repair through our global network of Delphi Diesel Centres. Replacing all wearable and performance critical parts, with like-for-like OE, and using OE-approved test plans and equipment, it offers a quality but economical solution.

Reman
For an equally fast, yet more cost-effective turnaround we offer a range of remanufactured parts. Available off-the-shelf, typically within one to two years of vehicle launch, they are built using OE parts, equipment and processes, and are calibrated to exacting OE specifications.


OE expertise in the aftermarket
Of course, we’re committed to supporting these technologies in the aftermarket. We offer a range of new OE components, identical to those originally fitted, including our pioneering Electronic Unit Injector, Electronic Unit Pump, Smart injector and Multec® Common Rail.
Commercial vehicle diagnostics and test
Our dedicated diagnostic solution for trucks, buses and trailers, supports the key commercial vehicle manufacturers and systems, including the ability to carry out dosing tests, Adblue freeze monitoring calibration, system drain down and regeneration of the SCR system. We also offer a range of OE-approved test equipment for quick and accurate test and repair of the latest heavy duty applications.
Training from the OE experts
Designed to help you prepare for the very latest heavy duty diesel fuel injection technologies, our extensive training programme covers the repair of key systems, including Electronic Unit Injector and Pump and Smart injectors. Learn more about our training.

Resource Highlights
Fitting a turbocharger is a time-consuming job that can take the best part of a day. Once you’ve installed the new part, it’s important to remember to calibrate it before giving the keys back to a customer.
In this Masters of Motion video our Delphi expert shares why calibrating a turbocharger is so important and how to do it. Discover:
Do I need to calibrate a newly fitted turbocharger?
Yes, calibrating a turbocharger is an essential job. If not carried out, it can lead to a number of performance issues.
How do I know what engine code to use?
Just enter the vehicle registration into the tablet and the software will find the engine code for you.
How long does it take to calibrate the turbocharger?
The actual calibration is a quick and easy job, taking a minute or so once you’ve input the correct details into the tablet.
Do I need to create a calibration certificate?
It’s a good idea to create a certificate – keep it in your records and give one to the customer as proof that calibration has been carried out.
