Diesel Injector Repairs

Not sure if the diesel injectors are faulty? Let us test them for you using the most up-to-date equipment. We’ll inform you of the test results and advise you on what would be the best course of action to take. You can trust us never to fail an injector without good reason.

Test reports are available before and after any diesel injector repair. New IMA (Injector Quantity Offset) codes will be issued, if applicable. Should the injectors be unrepairable, we can offer exchange units or the supply of new units.

The importance of injector coding

With ever-increasing emissions legislations and a tightening of limits, vehicle manufacturers need a way to control the flow of fuel pressure and atomisation more accurately – this in turn will optimise the efficacy of the combustion process, controlling emissions within acceptable limits. Introducing – injector coding! Injector coding allows the ECU to compensate for manufacturing differences of the injectors making sure that the delivery quantities allow for smooth running. Failure to code in the injectors can cause a number of issues.

  • Inefficient performance
  • Non-start of vehicle
  • Poor or lumpy running
  • Diagnostics/re-coding errors (in some vehicles)

This suite is capable of testing a range of commercial injector applications. Understanding the pressures that the commercial industry puts on users, we’re dedicated to offering our customers with 100% accurate and reliable diagnosis of all fuel injection units we analyse.

Did you know – in the time it takes you to blink once, a common rail injector would have injected 200 times? The injection takes place in just 1 to 2 milliseconds.
