GM/Opel 1.7 CDTi DENSO remanufactured common-rail diesel injector
A17DTS, LKR, LUD
Hard cold starting or no-start; rough or lumpy idle with shaking; misfire or intermittent running on fewer cylinders; knocking under load, smoke from the exhaust; limp mode, power loss or stuttering acceleration. When two or more appear together, suspect the injector before peripherals — a comparative leak-off test isolates the failed unit without tear-down.
Injector seal leakage — soot build-up, diesel smell and rough running (a recurring 1.7 cdti issue); fuel contamination or water in the fuel damaging the denso injectors; injector-driver electronics faults that log circuit codes without the injector itself being bad. Internal wear cannot be repaired in situ — once delivery drifts outside calibration, remanufacture or replacement is the reliable fix.
On this platform injector circuit codes frequently trace to the injector driver/ECU or wiring rather than the injector — test the electrical side before condemning hardware. Inspect injector seals for soot and smell — seal leakage is a documented recurring fault. Check fuel-filter service history and for fuel contamination before fitting replacements. Denso injectors carry an ID code — register the new code after fitting. Never condemn a common-rail injector on a fault code alone.
Each remanufactured DCRI300050 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 DCRI300050 trusted family covers 4 verified vehicle fitments across 2 makes: Chevrolet and Vauxhall. Every fitment listed is registry-verified.
DCRI300050 cross-references 6 further OE numbers, including 295050-0050, 2950500050, 821005, 55567729, 5-5567729C-A and 55567729CA. Always match the reference etched on your failed unit's body.
