Bosch 0445116059 – Common Rail Injector For F1CE 3.0D Engines

The 0445116059 is a Bosch common rail diesel injector engineered for high-mileage commercial vehicles and light-duty trucks that rely on the F1CE series engine platform. Designed to operate at pressures up to 1,800 bar, this injector delivers precise fuel metering for the 3.0D Multijet and HDi powerplants found in the Fiat Ducato, Iveco Daily, and Citroën Relay. For workshops dealing with rough idling, excessive smoke, or failed cylinder contribution, this OE-spec injector directly addresses the root cause of combustion inefficiency without requiring control unit modifications.

The injector features a solenoid-actuated design with a 7-hole nozzle configuration that atomizes diesel into a fine mist for complete combustion. This unit is supplied without a sealing ring (part number must be ordered separately if required) and has a net weight of approximately 0.62 kg . It operates within a fuel pressure range of 1,500 to 2,000 bar, ensuring consistent spray patterns even under high thermal loads. The injector body utilizes high-speed steel construction for the internal plunger and valve assembly, providing resistance against the corrosive effects of low-sulfur diesel and biodiesel blends. When installed, the injector requires a specific tightening torque of 70 Nm plus an additional 90-degree angle turn to achieve the correct preload on the copper sealing washer.

This injector is a direct OE replacement across multiple manufacturer brands, covering Euro 4 and Euro 5 emission standards. Below is the verified application and cross-reference data for workshop lookup:

Cross-Reference OE Numbers: 0445116019, 0986435395, 580540211, 504341488, 5801540211, 68226951AA, 1609848980, 500060378 .

Successful replacement of the 0445116059 injector requires strict adherence to the fuel return line and high-pressure pipe replacement procedures; old pipes must never be reused. Prior to installation, the injector bore in the cylinder head must be cleaned using a carbon-removing reamer to prevent binding and ensure proper seating. The electrical connector has a specific locking tab that must be fully engaged to prevent intermittent misfire codes (P0263 – P0266). Post-installation, a leak-off test is mandatory to verify internal valve integrity. A new copper gasket (often sold separately) is critical; reusing the old gasket will cause combustion gas blow-by, leading to rapid injector seizure and potential piston damage. Always clear the fuel trim adaptations stored in the ECU using a diagnostic tool to allow the new injector's calibration codes to take effect.

In the high-pressure common rail system, the injector is the final actuator controlling fuel quantity and timing. The 0445116059 specifically addresses the wear issue common in the F1CE engine family where the control valve wears due to fuel contamination. By replacing failed units, workshops restore cylinder balance, eliminate "black smoke" on hard acceleration, and reduce diesel particulate filter (DPF) regeneration cycles caused by excess soot. This Bosch unit provides a reliable alternative to expensive OEM dealership parts, offering a minimum 12-month warranty on remanufactured units and substantial labor savings. For fleets operating city delivery vans or refrigerated trucks, matching all cylinders with this matched injector ensures consistent power delivery and improves fuel economy by up to 8% compared to worn components, justifying the replacement cost within a single fiscal quarter.

Q1: Does the injector come with the required IMA code, and must it be programmed?
A: Yes, this unit uses an IMA (Individual Injector Adjustment) code. A diagnostic interface is required to input the 8-digit alphanumeric code into the ECU. Failure to program will result in rough running and a slight offset in fuel quantity .

Q2: What is the difference between the 0445116059 and the 0445116019 variant?
A: While physically similar, the 0445116059 is the later generation with different flow-rate calibration and valve lift specifications. The 0445116019 is often the earlier exchange variant. Always check the existing OE number on the rail; they are not direct cross-fit unless the ECU is re-flashed.

Q3: Are these genuine Bosch units or aftermarket copies?
A: We supply strictly Bosch-manufactured injectors (OEM) with proper hologram packaging. Avoid generic "no-brand" units which often use sub-standard solenoids that fail within 3-6 months.

Q4: What is the expected service life under normal fleet operation?
A: With proper fuel filtration (5-micron), these injectors typically last 150,000 to 200,000 miles. Primary failure drivers are water ingress and poor lubricity fuel.

Q5: Do you offer wholesale discounts for core returns?
A: Yes. We operate a core charge policy. Return your used, complete injector (with solenoid) to receive credit against your next bulk purchase. Contact our B2B team for tiered pricing.
