Genuine new Bosch 0445120270 CRIN4 common rail injector (Mercedes-Benz OE A 471 070 04 87 / A4710700487) for Mercedes-Benz Actros, Antos and Arocs heavy trucks with the 12.8 L OM 471 engine. Manufactured by Bosch in Germany and supplied in the sealed Bosch box, this is a direct OEM-quality replacement, not a remanufactured exchange unit.

The 0445120270 is a four-pin (CRIN4-21) solenoid common rail injector that meters and atomises diesel at high rail pressure for the OM 471 engine family. 0445120270 is the Bosch commercial service (order) number; 0445120271 is the equivalent Bosch number fitted to the engine as original equipment at the factory. Each injector is IMA-coded (individual injector accuracy), so the seven-character code printed on the injector body must be programmed into the engine ECU after installation.

Also known internationally as: Common Rail Injector (EN), Common-Rail-Injektor / Einspritzventil (DE), Injecteur Common Rail (FR), Iniettore Common Rail (IT), Inyector Common Rail (ES), Injector Common Rail (RO) — Bosch 0445120270.

OEM cross-reference numbers

Compare your original part number before ordering. The vehicle model alone is not sufficient to confirm compatibility — on the same engine Mercedes-Benz also fitted other injector codes (for example 0445120287 or 0445120385) that are not interchangeable. Always check the number on the injector installed on your engine.

Frequently asked questions

How do I know the Bosch 0445120270 fits my Mercedes-Benz truck? Confirm by the part number stamped on the injector you are removing, or by the Mercedes-Benz OE number A 471 070 04 87. It fits many Actros, Antos and Arocs variants with the 12.8 L OM 471 engine, but on the same engine Mercedes-Benz also fitted other injector codes (0445120287, 0445120385) that are not interchangeable — always check the code on your original injector.

Is this injector new or remanufactured? It is a genuine new Bosch injector, made in Germany and supplied in the original Bosch box. It is not a remanufactured exchange unit.

What is the difference between 0445120270 and 0445120271? They are the same injector. 0445120270 is the Bosch commercial service (order) number you buy; 0445120271 is the equivalent Bosch number fitted to the engine as original equipment at the factory.

Is Mercedes-Benz OE A4710700487 the same as this part? Yes. A 471 070 04 87 (and its variants A 471 070 04 87 80 / A 471 070 04 87 0080) is the Mercedes-Benz original-equipment reference for Bosch 0445120270.

What does IMA-coded mean and what do I do after fitting? Each injector carries an individual accuracy (IMA) code. After installation the seven-character code printed on the injector body must be programmed into the engine ECU with diagnostic equipment so the engine runs correctly.

Are there Bosch remanufactured references for this injector? Yes — the Bosch Exchange (remanufactured) references are 0986435598 and 0986435601. This listing is for a new unit.

What is included and how is it packed? You receive one Bosch 0445120270 injector (1.16 kg) in the original sealed Bosch packaging, boxed at 30 x 10 x 10 cm.

Do you ship worldwide? Yes, we ship worldwide.

Common symptoms of a failing common rail injector

A worn or leaking OM 471 injector can cause hard starting, rough idle, power loss, excessive smoke, higher fuel consumption or rail-pressure and injector fault codes. Because these engines run high rail pressures, have the fuel system professionally tested before replacing parts, and always renew the copper sealing washer and program the new IMA code on installation.
