Mercedes-Benz C-Class (W202) Diesel Injectors
About Mercedes-Benz C-Class diesel injectors
The Mercedes-Benz C-Class is one of the UK's busiest diesel-injector replacement jobs. From the W203 with its early OM611/OM646 four-pots, through the W204 OM651 — the engine that introduced the "black death" injector-seat leak that became the byword for diesel Mercedes — to the W205 / W206 OM654 with its NoX-trap-friendly piezo control, every C-Class generation eventually reaches us. We hold remanufactured injectors for all four engine families in our UK warehouse. Each unit is stripped fully, fitted with new internal seals, nozzle and valve, then recalibrated against a Bosch EPS 815 master rig. A new copper sealing washer ships with every injector, and the IMA classification code is supplied on the test certificate so the fitter can re-code the ECU in the same workshop visit. Order before 2 pm and the parts go out the same day, backed by our 12-month parts warranty.
Common injector faults on the Mercedes-Benz C-Class
- "Black death" — tar build-up around the injector seat from a leaking copper washer (OM651, very common past 80k)
- Cracked injector tips on OM611 / OM646 from high-mileage carbon polishing
- OM654 piezo stack drift causing intermittent cold-start misfires
- Hard-baked seized injector bodies on neglected OM651s (requires slide-hammer extraction)
Why choose remanufactured?
A genuine Mercedes OE injector lists at £450-£600 each, and dealers commonly insist on replacing all four. A remanufactured set covers the same job for a quarter of the cost, ships with a documented Bosch master-rig test sheet, and carries our 12-month warranty. We supply new copper washers in the box so you never need to reach for the old ones.
