1.9L dCi Remanufactured Common Rail Injector (Renault Megane/Scenic F9Q)
F9Q816, F9Q818
Hard starting or extended cranking; rough idle and hesitation; loss of power / limp mode; black smoke under acceleration; random 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 beyond specification causing rail-pressure loss; nozzle wear causing over-fuelling and smoke; fuel contamination damage following hp pump wear. 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 before condemning one. If the HP pump has failed, flush the complete fuel system before fitting replacement injectors. Replace the fuel filter and bleed the system fully after any injector work. Never condemn a common-rail injector on a fault code alone.
Each remanufactured 0445110280 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 0445110280 trusted family covers 3 verified vehicle fitments across 1 makes: Renault. Every fitment listed is registry-verified.
0445110280 cross-references 3 further OE numbers, including 0986435192, 8200535108 and 8200606383. Always match the reference etched on your failed unit's body.
