Frequently Asked Questions

How much does a diesel injector replacement cost?

A remanufactured diesel injector typically costs between £100 and £350 per injector. Labour adds £150–£400 depending on engine accessibility. Total per-injector cost usually ranges from £250 to £700.

Should I replace all injectors at once?

It is not strictly necessary, but many mechanics recommend replacing all injectors as a set. If one injector has failed, others are likely nearing the end of their service life, especially on high-mileage vehicles.

Is a remanufactured injector as good as a new one?

Yes. A properly remanufactured injector is stripped, cleaned, fitted with new internals, calibrated on a test bench, and sold with a warranty. Performance matches OE specifications at a fraction of the cost.

How long does it take to replace a diesel injector?

Replacing a single injector typically takes 1–2 hours. A full set of 4 injectors can take 3–5 hours depending on engine layout and whether any injectors are seized.

What are the signs I need a new diesel injector?

Common symptoms include rough idle, black or white exhaust smoke, poor fuel economy, engine misfires, hard starting, and loss of power under acceleration.
