This is the Bosch 0445116027, a new piezo common-rail fuel injector, not a rebuild, for the Mercedes-Benz OM642 3.0L V6 diesel in 2010 to 2022 Sprinter vans, both Mercedes-Benz and Freightliner badged. It replaces Mercedes-Benz A6420701287. Bosch’s remanufactured version of the same injector is 0986435406.

Hard starting, worst with the engine hot, a rough idle, a miss on one cylinder or smoke are the usual reasons an injector comes out of this engine. Carbon packed around an injector usually means the copper seal under it has been leaking, so check the seats before you blame the injectors. This is the 2010 and newer injector. The 2007 to 2009 Sprinter 3.0L takes Bosch 0445115061, Mercedes-Benz 6420701587, and catalogs list each one for its own years only. The engine takes six injectors.

Specifications

Fits / Applications

• 2010-2022 Mercedes-Benz Sprinter 2500 and 3500, 3.0L V6 diesel
• Freightliner Sprinter 2500 and 3500 with the 3.0L V6 diesel, 2010 and newer
• Sprinter 3500XD and 4500 with the 3.0L V6 diesel
• Not for the 2007-2009 Sprinter 3.0L. That van takes Bosch 0445115061 new or 0986435398 remanufactured.
• 3.0L V6 only. Four-cylinder Sprinters take a different injector.
• Six injectors per engine

Each injector is marked with a classification code. Write down the code for each cylinder and enter it in the engine computer with a scan tool when the injectors are fitted. The hold-down bolts on this engine are one-time-use stretch bolts, so fit a new bolt and a new copper seal with every injector. Clean the injector seat before the new seal goes in. A reused bolt or a poor seal lets combustion gas and carbon build up around the injector. Change the fuel filter and clear any dirty or watered fuel before start-up.

Does 0445116027 fit the 2019 to 2022 Sprinter as well?

Do these injectors have to be coded after they are installed?

Is 0445116027 new, and what else should I replace with it?
