Hard starting when warm; uneven idle with single-cylinder knock; loss of power / limp mode with rail-pressure faults; excess smoke on hard acceleration; individual cylinder misfire entries. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector back-leak rising with temperature on high-mileage units; nozzle wear causing over-fuelling on individual cylinders; electrical connector corrosion causing intermittent circuit faults. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Six-cylinder layout — always compare leak-off volumes across all six injectors, not just the suspect one. A warm-engine leak-off test is more conclusive than a cold test on this platform. Check smooth-running (cylinder balance) live data to identify the offending cylinder before removal. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445110047 is fully stripped, ultrasonically cleaned and inspected; worn components are replaced with OE-grade parts. The rebuilt unit is calibrated on a common-rail test bench against the manufacturer's specification — delivery, back-leak and response verified — and despatched with a 12-month parts warranty and its calibration data on file.
The 0445110047 trusted family covers 4 verified vehicle fitments across 1 makes: BMW. Every fitment listed is registry-verified.
0445110047 cross-references 24 further OE numbers, including 0445110266, 0445110039, 0986435022, 0986435017, 0986435018, 0986435019, 13534701464 and 13537785573. Always match the reference etched on your failed unit's body.
