0445120074 Bosch Common Rail Injector 04902525 for Renault Midlum II DXi 5 DXi 7 and Deutz TCD 2013

Genuine new Bosch 0445120074 common rail injector (OE 04902525, Renault Trucks 74 21 006 084, Volvo 21006084) for Renault Trucks Midlum II and Premium II Lander with DXi 5 and DXi 7 engines, Volvo B7R Urbano buses and Deutz TCD 2013 L04 4V engines. Made in Germany, supplied new in the original sealed Bosch box and covered by a 1-year manufacturer global warranty.

This solenoid-actuated heavy-duty common rail injector meters and atomises the diesel delivered from the rail at full system pressure. A correctly working injector restores the original spray pattern, an even idle and clean combustion across all cylinders of the listed 4.8 L and 7.2 L engines.

Also known internationally as: Common Rail Injector (EN), Common-Rail-Injektor (DE), Injecteur Common Rail (FR), Iniettore Common Rail (IT), Inyector Common Rail (ES), Injector Common Rail (RO) - Bosch 0445120074 for Renault Trucks Midlum II, Premium II Lander, Volvo B7R Urbano and Deutz TCD 2013.

Product details

OEM cross-reference numbers

Compare your original part number before ordering. Vehicle model alone is not enough for compatibility confirmation.

Vehicle and machine compatibility

Compatibility must always be verified by the original part number, OEM number, VIN or engine serial number. Model alone is not sufficient.

Manufacturers used different variants of these components depending on engine build, model, power rating, emissions stage and production date, so another code may be the correct one for your engine. Identification is by the number on the fitted part, not by the vehicle model.

Frequently asked questions

How do I know the Bosch 0445120074 fits my Renault Midlum, Premium Lander or Deutz TCD 2013 engine? Read the number laser-marked on the injector you are removing, or the number in the engine parts list, and compare it with the cross-reference table above. The engine code also helps: this injector covers the DXi 5 (4.8 L four-cylinder) and DXi 7 (7.1 to 7.2 L six-cylinder) engines and their Deutz TCD 2013 equivalents. Renault Trucks and Volvo used several injector variants across the DXi range, so the model name alone is not a confirmation.

What condition is this injector supplied in? It is a genuine new Bosch injector in the original sealed Bosch box, made in Germany, covered by a 1-year manufacturer global warranty.

Is my OE number 04902525 or 490 2525 the same part? Yes. 04902525 is the KHD / Deutz original-equipment number for this injector and it is laser-marked on the electrical connector of the unit we supply, as shown in the photographs. The same injector carries Renault Trucks 74 21 006 084 and 74 21 006 073 and Volvo 21006084.

What is the difference between 0445120074 and the numbers 0445120138 and 0445120139? 0445120074 is the Bosch order number, which is the code the part is sold and boxed under. 0445120138 and 0445120139 are the vehicle manufacturer service numbers (OES) for the same injector, that is the codes the engine and vehicle makers use in their own service catalogues. If one of those numbers appears in your parts list or on the injector you removed, 0445120074 is the Bosch code you order.

Does this injector need to be coded to the ECU after installation? No. This injector is supplied without an individual injector accuracy code (IMA/IQA), so no calibration value has to be written to the ECU with a diagnostic tool after fitting. The normal post-repair steps still apply: bleed the system and check rail pressure and return flow.

Should I replace all the injectors at the same time? Yes, the recommendation is to test and replace the complete set, which is four pieces on a DXi 5 or TCD 2013 L04 and six pieces on a DXi 7 or D7E. The injectors have run the same hours and are worn to a similar degree. Fitting one new injector next to worn ones leaves the cylinders working unevenly, and the new injector then runs under a different load than the rest and wears faster, which is why a partial replacement often ends in a second repair.

What is included in the package? One Bosch injector 0445120074 with its body O-ring, in the sealed Bosch box, packed at 0.606 kg in a 30 x 10 x 10 cm carton. The nozzle sealing washer is NOT included and must be sourced separately. Fitting a new sealing washer is recommended.

What is the difference between this injector and the Bosch Exchange number 0986435536? 0986435536 is the Bosch Exchange number, that is the Bosch remanufactured unit supplied on an old-part-exchange basis, and 0986435535 is listed alongside it as a further Bosch Exchange reference. What is offered on this page is the genuine new injector, delivered in the sealed Bosch box with no old part to return.

Which rail and connector tube belong with this injector? The four-cylinder engines use rail 0445224030 (CR/V4/10-23S) and the six-cylinder engines rail 0445226047 (CR/V6/10-23S); the injector inlet connector tube is F00RJ01457. Different variants were fitted depending on engine build and production date, so identify these parts by the number on the fitted component.

Do you ship worldwide? Yes, we ship worldwide.

Common symptoms of a failing common rail injector

On the DXi 5, DXi 7 and TCD 2013 engines a worn or leaking injector typically shows as hard starting or an engine that starts and then stalls shortly afterwards, a rough or hunting idle with an audible knock from one cylinder, black or white smoke under load, loss of power, high fuel consumption and an excessive return flow at that injector. Rail-pressure and injector-quantity diagnostic trouble codes are often stored with it. A professional fuel-system test must be carried out before replacing any parts, to confirm the injector is the actual cause of the fault.

Installation and system check

Before any injector is fitted, the fuel supply system must be checked for contamination, whatever caused the original fault. Check the fuel filter and its housing, because that is where debris and sticky deposits show first.

Affected components are cleaned or replaced: the tank, the supply and return lines, the filter housing and filters, the rail and the high-pressure pump. High-pressure lines and connector tubes such as F00RJ01457 are replaced, not cleaned. Flush the system, fit new filters and bleed it according to the manufacturer's procedure.

Poor or contaminated diesel is the usual cause, typically from badly stored fuel, tanks that are not cleaned periodically, or contaminated containers used for refuelling. Carry out all testing required to establish that the injectors are the actual cause of the fault before replacing any part.

Fit a new nozzle sealing washer, which is not included with this injector, and tighten the injector clamp and the high-pressure line to the engine manufacturer's torque figures. No IMA calibration code has to be written to the ECU for this injector. An injector fitted into a system that has not been decontaminated fails again within a short service period, and that failure is not covered by warranty.

Before the new injector is fitted, the fuel supply system must be checked for contamination. Rust, water, sludge or varnish-like deposits, metallic debris or any other contaminant left in the tank, supply and return lines, filter housing or rail will damage the new injector within a short service period, and that damage is not covered by the warranty. Inspect and decontaminate the system, renew the filters and confirm that the fuel is clean before installation.
