Bosch 0445116027 3.0 CDI/CRD (OM642) V6 Piezo Common Rail Injector (Mercedes/Jeep)

AI Technical Summary

Bosch piezo common-rail injector for the Mercedes-Benz 3.0 V6 diesel (OM642), also used on the Jeep/Chrysler 3.0 CRD. Bosch exchange 0986435406; Mercedes OE A6420701287 (and related A6420701187). Bosch alternate 0445116028. Piezo and solenoid injectors are not interchangeable. Replacements are coded to the ECU. Failures are driven by poor fuel filtration, contamination and back-leakage. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Piezo stack degradation; Nozzle coking.

Common Symptoms

Rough idle / vibrationhigh

A leaking injector unbalances cylinder fuelling on the 3.0 V6.

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 calibration value to the correct cylinder with XENTRY/diagnostic before road test.
InstallationRenew the combustion seal and hold-down hardware; clean the injector bore to prevent 'black death' carbon build-up.
WarningPiezo and solenoid injectors are not interchangeable - confirm 0445116027 (piezo) and the exact OE before ordering.
MisdiagnosisRead live back-leakage / cylinder-balance data to find the weak cylinder before removal.
TestingBench-test on a piezo-capable CR tester; verify response and spray pattern before refit.
