Diesel Injector Testing & Repairs

Edinburgh and the Lothians Diesel Injector Testing 

With our Bosch test bench we can test, most electrically controlled diesel injectors (Except PD unit injectors) and supply you a detailed comprehensive report for each individual injector. We can repair many older style units as well.


Located in East Lothian, we offer a speedy inhouse service and aim for a same day turn-around for testing and of around and 2-3 working days if any repairs are required  depending on our workload, with a next day postage and signed for service if required.


We carry out the following diesel injector tests on electronic units, and will present you with a detailed and comprehensive printed report showing a clear no quibble "Pass or Fail" test result.


- Solenoid Resistance Test

- Solenoid Inductance Test

- Injector Back leakage test

- Spray Pattern Check

- Flow Rates for Pilot, Pre, main and post Injection Phases* (*where applicable).

- Insulation test.



Our diesel specialist technician has over 30+ years extensive experience in this field, a claim few others can match...


With high injector replacement costs, "Test not Guess" is the professionals route in diagnostics.  Testing injectors should be an essential and key part of your diagnostic process, and can save many hours chasing faults with starting, running and smoke issues,  or at worst... an engine failure. Not all injector faults will show up with a fault code/s, but an extensive testing program can rule them out, or prove to you or your customer that an issue exists.
