0445110254 — Technical Research
Bosch solenoid common-rail injector for the Hyundai 2.2 CRDi (engine D4EB) fitted to the Santa Fe II (CM) and Grandeur (TG). Hyundai OE 33800-27800; Bosch interchangeable 0445110253; nozzle DLLA150P1512. Replacements are coded to the ECU with the injector correction value. 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.

A leaking injector unbalances cylinder fuelling on the 2.2 CRDi.
Excess back-leakage drops cranking rail pressure.
Out-of-range delivery or rail-pressure deviation cuts power.
Poor atomisation over-fuels the cylinder.
Cylinder-specific injector or fuel-metering codes.
- InstallationCode the injector correction value to the correct cylinder with Hyundai GDS before road test.
- InstallationRenew the combustion washer 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 2.2 CRDi is sensitive to fuel quality.
- TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
