Bosch 0445110212 Diesel Injector

On the 2.0d platform, a failing Bosch 0445110212 injector typically presents as: rough idle or vibration — engine feels like it is running on three cylinders; hard starting, especially cold; white smoke on cold start; black smoke under acceleration; uneven running under load, 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 internal leakage (high leak-back) preventing rail pressure from building; injector imbalance showing as uneven cylinder correction values; injector seal / washer leakage with soot or fuel around the injector base.

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

Rule out air leaks and fuel-supply faults first — they mimic injector failure on the M47. Compare requested vs actual rail pressure in live data before condemning injectors. Run an injector leak-back test to spot excessive internal leakage. Check injector correction / smooth-running values where the scan tool supports it.

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 0445110212 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 0445110212 trusted family covers 5 verified vehicle fitments across 1 make: BMW. Every fitment listed on this page is registry-verified — no scraped or assumed applications.

0445110212 supersedes or cross-references 9 further OE numbers, including 0986435151, 7791545, 7794434, 7749652, 13537749652, 13537794434, 13537791545 and 13537794652. 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.
