Bosch 0445110064 Diesel Injector

On the 2.0L CRDi platform, a failing BOSCH 0445110064 injector typically presents as: hard starting or cranking without catching, especially cold; rough or unstable idle that improves at higher rpm; misfire, hesitation or surging under acceleration; black smoke under load, white/grey smoke on cold start; injector knock / ticking at idle.

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 wear or internal leakage — documented as the main weak point of this otherwise robust bosch common-rail system; nozzle wear from poor-quality diesel degrading the spray pattern; external injector leakage allowing fuel smell or fuel dilution of the oil in advanced cases.

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

Run a return-flow (leak-off) test — severe internal leakage is the classic D4EA no-start cause. Rule out rail-pressure regulator and sensor faults, which mimic injector failure on this engine. Monitor the engine-oil level on suspected leaking injectors. Clean injector bores and seats and fit new sealing washers on every refit.

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 0445110064 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 0445110064 trusted family covers 6 verified vehicle fitments across 2 makes: Hyundai and Kia. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

0445110064 supersedes or cross-references 8 further OE numbers, including 0445110101, 0986435094, 33800-27010, 3380027010, 33800-27000, 3380027000, 33800-27900 and 3380027900. 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.
