1.6L CRDi · Remanufactured
Hyundai/Kia 1.6 CRDi (U2) Bosch CRI2 remanufactured common-rail injector
D4FB, D4FB-L
Rough idle that may smooth out at higher revs; knocking or ticking at idle or under light load; hard cold starts, occasionally hard hot starts; black smoke under acceleration or load; reduced power, hesitation or limp mode as the fault worsens. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector correction values drifting to their compensation limit; injector coding loss after previous work — rough running and knock without a clear stored fault; injector back-leak beyond specification affecting rail pressure. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Verify injector coding first — lost or wrong codes cause knock and rough running with no stored fault on this engine. Read injection correction values: a unit at its compensation limit identifies the failing injector. DPF, EGR and fuel-supply restrictions mimic injector faults on the 1.6 CRDi — rule them out before replacing hardware. Register the new injector code after fitting per the manufacturer procedure. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445110320 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 0445110320 trusted family covers 4 verified vehicle fitments across 2 makes: Hyundai and Kia. Every fitment listed is registry-verified.
0445110320 cross-references 3 further OE numbers, including 0445110319, 0986435186 and 338002A900. Always match the reference etched on your failed unit's body.
