Engine Intelligence

Mercedes 2.1 CDI (OM651.950-era — Bosch solenoid injection, C/E-Class, Sprinter, Vito) OM651950

Common symptoms

Hard starting, especially cold
Rough idle or vibration
Diesel smell from the oil dipstick or a rising oil level
Black carbon build-up around an injector base
Misfire-like running with the warning light on

Documented failure modes

Injector seal leakage — the documented weak point of the later solenoid-injected engines, producing blow-by and carbon ('black death') around the injector base
Fuel dilution of the engine oil from a leaking injector
Injector wear degrading idle quality on high-mileage engines

Diagnostic guidance

Inspect around every injector for black crust — on this era the seal and seat are the usual culprits, not the injector body
Check the engine oil for diesel smell or a rising level: fuel dilution is a stronger warning sign than rough idle alone
Clean or recut the injector seat and fit a new sealing washer on every refit
Check injector correction values across all four cylinders to identify an outlier

Bosch 0445110574 2.1 CDI Common Rail Injector (Mercedes C/E-Class, Sprinter, Vito OM651 — Bosch supplier)

AI Technical Summary

Bosch 0445110574 (Bosch 0445110573, exchange 0986435286, OE A6510703187) CRI2 common-rail injector for the Mercedes-Benz 2.1 CDI OM651 — the Bosch-supplier variant. The OM651 was factory-fitted with two injector suppliers; the Delphi-supplied OM651 injector is a separate authority (28342997). Not interchangeable — confirm the Bosch OE A6510703187 marking. Remanufactured, calibrated, 12-month warranty. Key symptoms: Rough idle / vibration; Hard starting; Loss of power / limp mode; Black smoke. Common failure modes: Internal wear / high back-leakage; Nozzle coking / poor spray pattern; Water-in-fuel corrosion.

Common Symptoms

Rough idle / vibrationhigh

A leaking or out-of-calibration injector unbalances cylinder fuelling, felt as a shake at idle.

Hard startinghigh

Excess back-leakage bleeds rail/line pressure during cranking, causing long or failed starts.

Loss of power / limp modehigh

Out-of-range delivery or pressure deviation triggers a torque cut and limp home.

Black smokemedium

Poor atomisation or a dribbling nozzle over-fuels the cylinder.

Engine management lightmedium

Cylinder-specific injector, balance or fuel-metering fault codes are logged.

Workshop & Fitting Notes

InstallationCode each injector's calibration code to the correct cylinder with Mercedes Xentry on fitment before road test.
InstallationRenew the copper combustion washer and leak-off seals; torque the clamp/nut to manufacturer spec.
MisdiagnosisRead live back-leakage and per-cylinder contribution data to confirm the weak cylinder before removal.
TestingBench-test across delivery and back-leakage points and verify spray pattern before refit.
WarningConfirm fitment by OE number and engine code before ordering; injector sub-variants are not always interchangeable.

Frequently Asked Questions

What is injector 0445110574?+

0445110574 is a Bosch common rail solenoid injector (cri2) diesel injector for the Mercedes-Benz 2.1 CDI (OM651, Bosch supplier). It is supplied remanufactured, bench-tested and calibrated to OEM specification.

Which vehicles use 0445110574?+

It is fitted to the Mercedes-Benz 2.1 CDI (OM651, Bosch supplier) — including Mercedes-Benz C-Class (W204) 200/220 CDI (OM651, Bosch); Mercedes-Benz E-Class (W212) 200/220 CDI (OM651, Bosch); Mercedes-Benz GLK (X204) 200/220 CDI (OM651, Bosch); Mercedes-Benz Sprinter (906) 210/213/313/316 CDI (OM651, Bosch). Confirm fitment by OE number and engine code.

What type of injector is 0445110574?+

It is a Bosch Common Rail Solenoid Injector (CRI2). Always confirm the OEM markings on the injector body before fitting.

Does 0445110574 need coding when fitted?+

Yes — each OM651 injector has a calibration code that must be programmed to the correct cylinder with Mercedes Xentry on fitment.

What are the symptoms of a failing 0445110574?+

Common signs are rough idle and vibration, hard starting, power loss or limp mode, black smoke and an engine-management light.

What causes these injectors to fail?+

Most failures come from poor fuel filtration, contamination and water in the fuel leading to wear, high back-leakage and nozzle coking. Fix the cause before fitting replacements.

Is a remanufactured 0445110574 as good as new?+

A properly remanufactured injector is stripped, fitted with new wear parts, reassembled and recalibrated on a common-rail test bench to OEM tolerances, then supplied with a warranty.

Should I replace one injector or the full set?+

Replace the confirmed faulty injector first. On high-mileage engines fitting a matched set reduces the chance of a repeat fault, but it is not mandatory if the others test within spec.

Do you bench-test the injector before dispatch?+

Yes. Every unit is tested for delivery, back-leakage and spray pattern on a calibrated common-rail tester before it leaves us.

Is delivery and warranty included?+

Yes — the price includes free UK delivery and a 12-month warranty.

Is the Mercedes OM651 a Bosch or Delphi injector?+

The OM651 2.1 CDI was factory-fitted with both. This 0445110574 is the Bosch-supplier injector (OE A6510703187); the Delphi-supplier injector is a separate part (e.g. A6510704987). They are not interchangeable — confirm the OEM marking before ordering.

Does the Mercedes OM651 injector need coding?+

Yes — each OM651 injector carries a calibration code that must be programmed to the correct cylinder with Mercedes Xentry on fitment.
