Injector Coding & Diesel Repairs

Expert injector testing, replacement and coding for optimal fuel efficiency, performance and smooth running.

Injector Coding & Diesel Repairs at DM Auto Mechanics

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.
