Which engines use the Bosch 0445110263 injector?

0445110263 is verified for the 2.2L CDI platform, covering engine code OM646.983. Confirm the engine code on your V5C before ordering.

Which vehicles does 0445110263 fit?

This family has 2 verified fitments across Mercedes-Benz — the full registry-verified list is on this page.

My injector is etched with a different number — is it the same part?

0445110263 cross-references 0445110264, 0986435115, 0445110179, 0445110180, 0986435116 and 6460700487 among others. If your etched number appears in this family's reference list it is a verified equivalent; if not, send us a photo of the etching and we will confirm before you order.

Do I need to code the replacement injector to the ECU?

Yes on common-rail diesels. Every injector ships with an individual calibration code that must be written to the ECU after fitting, following the manufacturer procedure — without it the engine runs on default trims and can log cylinder-balance faults.

How is each injector tested before despatch?

Every unit is bench-calibrated against the manufacturer specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data retained on file.

Common failure symptoms

On the 2.2L CDI platform, a failing Bosch 0445110263 injector typically presents as: chuffing / ticking noise from the injector area; diesel smell in the engine bay; hard starting and uneven idle; black smoke under load; loss of power with rail-pressure faults.

When two or more of these appear together, suspect the injector before peripheral systems — a comparative leak-off test and live-data cylinder-balance review will isolate the failed unit without tear-down.

When two or more symptoms appear together, suspect the injector before peripherals (EGR, glow plugs, turbo). A live-data leak-off test on each cylinder is the fastest route to the failed unit.

What Causes These Injectors To Fail

The documented failure modes on this platform are: injector seat sealing failure allowing combustion gas blow-by and carbon build-up around the injector (widely documented on this engine family); injector back-leak beyond specification; nozzle wear causing over-fuelling.

Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.

How Workshops Diagnose 0445110263 Faults

Inspect around each injector for hardened carbon from seal blow-by before diagnosis — clean the seat thoroughly before fitting a replacement. Always fit a new copper sealing washer and follow the manufacturer seating procedure. Run a comparative leak-off test across all injectors before condemning one.

Never condemn a common-rail injector on a fault code alone — codes identify the circuit or cylinder, while leak-off volumes and correction values identify the component.

How Every Unit Is Tested Before Despatch

Each remanufactured 0445110263 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is then calibrated on a common-rail test bench against the manufacturer's specification sheet — delivery, back-leak and response are all verified before the injector is sealed and despatched with its calibration data on file.

Every unit carries a 12-month parts warranty and free UK delivery.
