Injector Coding & Diesel Repairs
Expert injector testing, replacement and coding for optimal fuel efficiency, performance and smooth running.

Modern common-rail diesels and direct-injection petrol engines need every injector matched to the engine computer. When injectors are replaced – or swapped between cylinders – they must be coded, or the engine runs rough, smokes and uses more fuel.
We test injector leak-back and balance rates, replace and code injectors, and repair the rest of the fuel system: rails, pressure sensors, high-pressure pumps and EGR faults.
What’s included
- Injector balance & leak-back tests
- Injector replacement
- Injector coding to the ECU
- Rail pressure & sensor checks
- EGR & DPF diagnostics
Signs you need this
Diesel rough idle, smoke or hard starting
- Worn or leaking injectors
- Injectors not coded after replacement
- Low rail pressure or fuel filter
- Sticking EGR valve
Diesel injectors must be tested and coded to the ECU. A rough idle or black smoke caught early usually avoids a much bigger bill.
