Refurbished, Reconditioned & Reman Diesel Injectors UK
We are a UK diesel injector specialist supplying remanufactured injectors, refurbished injectors and reconditioned diesel injectors for Bosch, Delphi, Denso and Siemens VDO common-rail systems. Every reman injector we ship has been stripped, ultrasonically cleaned, fitted with new nozzles and seals, and flow-tested back to original manufacturer tolerances on Bosch and Delphi test equipment. The result is a workshop-grade rebuild that behaves identically to a new OEM unit on idle delivery, full-load delivery, back-leakage and spray pattern.
Each recon injector ships with a 12-month warranty, free UK delivery and same-day dispatch before 2 pm. Vehicle compatibility is matched against your engine code or registration before despatch, so the part fits first time — no guesswork on dealers’ cross-references. We supply garages, independents and DIY technicians across the UK with calibrated diesel injectors for BMW, Mercedes-Benz, Audi, Volkswagen, Ford, Vauxhall, Peugeot, Citroën and most other common-rail diesels. Looking at the trade words: refurbished, reconditioned and remanufactured all describe the same process — a rebuilt core tested to OEM spec. We use remanufactured because every injector is calibrated, not just visually cleaned.

Diesel Injector FAQs
The questions UK garages and drivers ask us most often. Real answers from our remanufacturing specialists.
How do I find the right injector for my vehicle?
Simply enter your UK vehicle registration on our website. We'll look up your vehicle and show compatible injectors instantly. Alternatively, call us on 020 3355 6581 with your reg number for expert assistance.
Are remanufactured injectors as good as new?
Yes! Our remanufactured injectors are stripped, cleaned, fitted with new components, and tested to OEM specifications. They perform identically to new injectors at 40-60% less cost, backed by our 12-month warranty.
How quickly can you deliver?
We offer next working day delivery on orders placed before 2pm (UK mainland). Standard delivery is 2-3 working days. Same-day dispatch available. Free UK delivery on all orders.
Do you supply injectors for commercial vehicles?
Yes, we supply injectors for cars, vans, trucks, and commercial vehicles. We stock injectors for Ford Transit, Mercedes Sprinter, VW Transporter, Iveco Daily, and many more commercial applications.
What payment methods do you accept?
We accept all major credit and debit cards, PayPal, and bank transfer. All payments are SSL encrypted and secure. Pay with confidence knowing your transaction is protected.
What is the difference between refurbished and reconditioned injectors?
In the UK diesel trade, refurbished, reconditioned and remanufactured injectors are largely the same thing — used cores stripped, cleaned, fitted with new nozzles and seals, and flow-tested back to OEM specification. We use the term remanufactured because every unit is rebuilt to original manufacturer tolerances on Bosch and Delphi test equipment, then issued a 12-month warranty.
How long do diesel injectors last?
A well-maintained common-rail diesel injector typically lasts 100,000–150,000 miles. Lifespan drops sharply when fuel quality is poor, fuel filters are neglected, or contamination enters the fuel system. Our remanufactured injectors are tested to original flow tolerances so once fitted, they restore full service life under normal driving conditions.
Are diesel injectors covered under warranty?
Yes — every remanufactured diesel injector we supply includes a 12-month warranty as standard, covering manufacturing defects and premature failure when fitted by a competent installer with clean fuel. No registration cards or activation forms required — warranty starts automatically from the purchase date on your order.
Can faulty injectors damage an engine?
Yes. A leaking or over-fuelling diesel injector can wash the cylinder bore of oil, melt piston crowns, dilute engine oil with raw diesel, and dump unburnt fuel into the DPF and turbo — bills running into thousands of pounds. The cheapest insurance is to test or replace a suspect injector early. Our common-rail testing service is £20 per injector with a full diagnostic report.
What causes injector failure?
The two biggest causes of diesel injector failure are fuel contamination (water, debris, wrong fuel) and worn nozzles from high mileage. Other common causes: a clogged fuel filter that wasn't changed on schedule, low-quality biodiesel, dirt ingress during a botched repair, and tuning that pushes injection pressure beyond stock limits. Regular filter changes and clean fuel are the single best preventative measures.
Is it better to replace all injectors at once?
On a single faulty injector replacing just that unit is often fine — but on engines past 100,000 miles or where multiple injectors test marginal, replacing a full set rebalances cylinder fuelling, prevents another return-to-workshop in a few months, and is usually cheaper per unit. We offer set pricing on most engines and free UK delivery on all orders.
How much does injector replacement cost in the UK?
For a remanufactured diesel injector from us, expect £80–£180 per unit depending on engine and brand. Fitting labour at an independent garage typically adds £80–£200 per injector. A full set of 4 injectors fitted in the UK usually lands between £700 and £1,400 — substantially less than the £1,800+ that main-dealer new units cost on the same vehicle.
