Delphi 28231462 1.2 TDI (CFWA) Common Rail Injector (VW Polo / Skoda Fabia-Roomster / Seat Ibiza)

AI Technical Summary

Delphi solenoid common-rail injector for the VW 1.2 TDI (engine CFWA, Euro 5) fitted to the VW Polo V, Skoda Fabia II / Roomster and Seat Ibiza. VW OE 03P130277. Each injector carries a 20-character IMA/adaptation code that must be converted and written to the ECU (adaptation channel 10) with VAG ODIS/VCDS. 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 1.2 TDI.

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

InstallationConvert and write the 20-character IMA code to the correct cylinder (adaptation channel 10) with VAG ODIS/VCDS 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.
WarningDo not mix genuine and aftermarket injectors on the 1.2 TDI; fix contamination first.
TestingBench-test on a Delphi-capable CR tester across delivery and back-leakage points before refit.
