Bosch 0445110263 2.1 CDI (OM646) Common Rail Injector (Mercedes Vito / Viano W639)

AI Technical Summary

Bosch solenoid common-rail injector for the Mercedes OM646 2.1 CDI (OM646.982/983) fitted to the Vito and Viano (W639), and also seen on related OM646 vans. Mercedes OE A6460700487; related Bosch family number 0445110179. Each injector must be coded to its cylinder position with Mercedes Xentry after fitting. 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 2.1 CDI.

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

InstallationCode the injector correction value to the correct cylinder with Mercedes Xentry before road test.
InstallationRenew the combustion seal and heat-shield/clamp hardware; torque to spec.
MisdiagnosisRead live back-leakage data to find the weak cylinder before removal.
WarningFix contamination (filter/water/debris) first; the OM646 is sensitive to fuel quality.
TestingBench-test across delivery and back-leakage points; verify spray pattern before refit.
