0445110059 — Technical Research
Bosch solenoid common-rail injector for the VM Motori 2.8-litre diesel (engine ENR) fitted to the Chrysler Voyager 2.8 CRD and Jeep Cherokee / Liberty 2.8 CRD. Chrysler OE 05066820AA. A Bosch trim code is written to the ECU on fitment. The VM 2.8 is sensitive to fuel filtration; failures are driven by 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.

Bosch solenoid common-rail injector for the VM Motori 2.8-litre diesel (engine ENR) fitted to the Chrysler Voyager 2.8 CRD and Jeep Cherokee / Liberty 2.8 CRD. Chrysler OE 05066820AA.

A leaking injector unbalances cylinder fuelling on the VM 2.8.
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.
- InstallationWrite the Bosch trim code to the correct cylinder with the dealer diagnostic tool 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.
- WarningConfirm the OE number 05066820AA stamped on the old injector; the VM 2.8 is sensitive to fuel quality - fix contamination first.
- TestingBench-test on a Bosch-capable CR tester across delivery and back-leakage points before refit.
What is Bosch injector 0445110059?+
A Bosch solenoid common-rail diesel injector for the VM Motori 2.8 CRD (engine ENR). Chrysler OE 05066820AA.
Which vehicles use 0445110059?+
Chrysler Voyager 2.8 CRD and Jeep Cherokee / Liberty 2.8 CRD, roughly 2004-2010.
Is it solenoid or piezo?+
It is a Bosch solenoid common-rail injector.
Does 0445110059 need coding?+
Yes - write the Bosch trim code to the correct cylinder with the dealer diagnostic tool when fitting.
What is the OE part number?+
Chrysler 05066820AA references Bosch 0445110059.
Which engine is this for?+
The VM Motori 2.8-litre common-rail diesel (engine code ENR) used by Chrysler and Jeep; confirm the OE number stamped on your injector.
What are the symptoms of failure?+
Rough idle, vibration, hard starting, black smoke, power loss/limp mode and an EML.
Why does my 2.8 CRD run rough?+
A worn or leaking injector unbalances fuelling; read live back-leakage data and bench-test the weak cylinder.
What causes these injectors to fail?+
Poor fuel filtration, contamination and back-leakage wear - fix the cause first.
Does a remanufactured 0445110059 perform like new?+
A properly remanufactured injector is bench-tested and recalibrated to the Bosch plan, then trim-coded on fitment.
