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 DCRI301030 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 DCRI301030 trusted family covers 2 verified vehicle fitments across 1 makes: Vauxhall. Every fitment listed is registry-verified.
DCRI301030 cross-references 4 further OE numbers, including 2950501030, HU2950501030, 55578075 and 821047. Always match the reference etched on your failed unit's body.
