Bosch 0445110236 Diesel Injector

On the 2.2L i-CTDi/i-DTEC platform, a failing Bosch 0445110236 injector typically presents as: rough or uneven idle with vibration; hard starting / long cranking, especially cold; diesel smell in the cabin or engine bay; chuffing noise with sooty, tar-like deposits around the injectors; reduced power, flat spots and higher fuel consumption.

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.

The documented failure modes on this platform are: injector copper washer / seal failure allowing exhaust blow-by around the injector (documented on this engine); injector back-leak beyond specification; nozzle wear causing over-fuelling and smoke.

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

Inspect around each injector for blow-by deposits — replace leaking washers early to keep combustion gas out of the injector bore. Clean the injector seat thoroughly and fit a new copper washer on every refit. Run a comparative leak-off test across all four injectors before ordering. Injector coding is required after fitting — follow the manufacturer procedure.

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.

Each remanufactured 0445110236 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.

The 0445110236 trusted family covers 4 verified vehicle fitments across 1 make: Honda. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

0445110236 supersedes or cross-references 9 further OE numbers, including 0986435145, 0445110172, 16450RBDE01, 16450RMAE01, 16450RMAE011, 16450RBDAE010, 16450RMAXE000 and 1077500210. Always match the reference etched on your failed unit's body — cross-references within a family are verified equivalents, but etched numbers remain the source of truth.
