1.5L CRDi · Remanufactured
Hyundai/Kia 1.5 CRDi (D4FA) Bosch CRI2 remanufactured common-rail injector
D4FA, D4FA-G, S3FA, D4FA-L
Rough or hunting idle that improves at higher revs; hard starting or long cranking, especially cold; hesitation, flat spots or sluggish response under load; black smoke under load, white smoke on start-up; knock-like ticking at idle, higher fuel consumption. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector wear or imbalance producing knock and rough idle; injector internal leakage bleeding off rail pressure and causing hard starts; leaking injector or seal producing diesel smell around the engine bay. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Run a leak-off comparison across all four injectors — internal leakage is the classic hard-start cause on this engine. A rough idle that smooths at higher rpm is the typical injector-wear signature. Check for diesel smell or wetness around the injectors on suspected seal leaks. Injector coding is required after fitting — follow the manufacturer procedure. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445110255 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 0445110255 trusted family covers 4 verified vehicle fitments across 2 makes: Hyundai and Kia. Every fitment listed is registry-verified.
0445110255 cross-references 6 further OE numbers, including 0445110256, 0986435152, 0445110241, 0445110727, 338002A400 and 33800-2A400. Always match the reference etched on your failed unit's body.
