Denso DCRI105080 1.7 CDTI (A17DTR/Z17DTR) Common Rail Injector (Vauxhall/Opel Astra H, Corsa D, Meriva, Zafira B)

AI Technical Summary

Denso common-rail injector for the GM/Opel 1.7 CDTI (Isuzu-built Circle-L engine, codes A17DTR/Z17DTR, 92 kW / 125 hp) fitted to the Astra H, Corsa D, Meriva and Zafira B. OE 8-97313861-0 (GM short reference 97313861). The injector code must be written to the ECU with GM MDI/Tech2 on fitment. Failures are driven by poor fuel filtration, contamination and back-leakage wear. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Water-in-fuel corrosion; Nozzle coking.

Common Symptoms
Rough idle / vibrationhigh

A leaking injector unbalances cylinder fuelling on the 1.7 CDTI.

Hard startinghigh

Excess back-leakage drops cranking rail pressure.

Loss of power / limp modehigh

Out-of-range delivery or rail-pressure deviation cuts power.

Black smokemedium

Poor atomisation over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector or fuel-metering codes.

Workshop & Fitting Notes
  • InstallationWrite the injector code to the correct cylinder with GM MDI/Tech2 before road test.
  • InstallationRenew the combustion seal and clamp hardware; torque to spec.
  • MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
  • WarningFix contamination (filter/water/debris) first; the 1.7 CDTI is sensitive to fuel quality.
  • TestingBench-test on a Denso-capable CR tester across delivery and back-leakage points before refit.
