Diesel Injector Testing & Replacement in Newcastle
Rough idle, black smoke, hard starting, or fuel economy quietly getting worse? It’s often the injectors. We test before we replace — so you only pay for the parts that have actually failed.

The problem
Injectors wear out — especially on hard-working towing and touring diesels. The signs creep in: a rattly idle, a puff of smoke on start-up, harder cold starts, climbing fuel use, sometimes limp mode.
The trap is shops that replace every injector on a guess. On a modern common-rail diesel that’s thousands of dollars you may not need to spend.
What we do
We test first. Your injectors come out and go on the bench, where we measure spray pattern, flow and back-leakage against spec. Then we tell you exactly which injectors are faulty, which are fine, and what it’ll cost.
The service includes:
- Diagnostic scan and symptom assessment
- Injector removal and bench testing (flow, spray pattern, back-leakage)
- Quality OEM-spec replacement injectors
- Correct coding/calibration to your ECU
- Post-fit road test
What you can expect
- An honest answer on which injectors are actually faulty — not a blanket “replace all six”
- Smooth idle, clean starts and the smoke gone
- Fuel economy back where it should be
- A written record of what was tested and replaced
