Bosch 0445110215 Diesel Injector

On the Toyota 1.4 D-4D (1ND-TV) platform, a failing Bosch 0445110215 injector typically presents as: hard starting or extended cranking; rough idle and hesitation; loss of power under load; black smoke under acceleration; poor fuel economy.

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 back-leak beyond specification; nozzle coking on short-journey duty cycles; electrical coil faults logging injector circuit codes.

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

Denso injectors carry compensation codes — register the new code with a capable scan tool after fitting. Run a leak-off comparison across all four injectors before condemning one. Clean injector bores and use 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 0445110215 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 0445110215 trusted family covers 5 verified vehicle fitments across 1 make: Toyota. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

0445110215 supersedes or cross-references 16 further OE numbers, including 0445110214, 0445110085, 0445110153, 0445110154, 107750-0084, 1077500084, 13537795259 and 7795259. 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.
