Hard starting or extended cranking; rough or uneven idle; loss of power under load; excess smoke from the exhaust; cylinder misfire or contribution fault codes. 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; nozzle wear degrading the spray pattern; combustion gas leaks past the injector seat washer. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
Run a comparative leak-off (back-leak) test across all injectors before condemning a single unit. Compare requested vs actual rail pressure in live data at idle and under load. Inspect injector connectors and wiring before replacing hardware. Never condemn a common-rail injector on a fault code alone.
Each remanufactured BK2Q-9K546-AG 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 BK2Q-9K546-AG trusted family covers 9 verified vehicle fitments across 4 makes: Citroen, Ford, Land Rover and Peugeot. Every fitment listed is registry-verified.
BK2Q-9K546-AG cross-references 19 further OE numbers, including A2C59517051, 562002210, AAA9858830010, 1717686, 1728574, 1745686, 1746967 and 1760803. Always match the reference etched on your failed unit's body.
