Cheap Mercedes-Benz E-Class Fuel Injector

This is a critical boundary to flag: the W212 E-Class ran from 2009 to 2016, with a facelift in 2013, but the engine code matters far more than the year alone. If both cars share the same engine code — for example both running the OM651 2.2 diesel — there is a reasonable chance of compatibility, but mid-production ancillary and mounting changes around the 2013 facelift mean you should confirm the exact part number with the breaker against your registration before buying.

All variants of the Mercedes-Benz E-Class have fuel injectors, both petrol and diesel — diesel engines use high-pressure common-rail injectors (such as Bosch or Delphi units on engines like the OM651), while petrol engines use either port or direct fuel injectors depending on the generation and engine. The type, design, and fitment of the injector differ significantly between fuel types, so you must ensure you are quoting for the correct fuel type. Supplying your engine code to the breaker is the quickest way to make sure you get the right unit.

No — SE, Sport, AMG Line, Exclusive, and other trim designations on the E-Class are cosmetic and equipment-level distinctions that have no bearing on the fuel injector fitted. What matters is the engine code: two E220d models with the same engine code will use the same injector regardless of which trim level they are. Focus entirely on matching the engine code rather than the badge or trim name.

The W211 ran from 2002 to 2009 and the W212 from 2009 to 2016, and these are distinct generations with different engine families, so a direct swap between generations is very unlikely even if the displacement looks similar on paper. Engine codes changed significantly between the two generations — for instance the OM648 and OM642 diesels in the W211 era differ from the OM651 used in the W212. Always quote your engine code to the breaker and ask them to match on that rather than assuming year-to-year compatibility across generations.

The W213 generation launched in 2016 and shares no engine codes with the W212 in any straightforward way, so cross-generation fitment of fuel injectors is highly unlikely. Beyond the physical differences, fuel injectors on modern Mercedes engines can involve ECU pairing and coding considerations that you should confirm with the breaker before purchasing a used unit. Give the breaker your exact engine code and registration so they can match the correct injector from their stock.

Whether a used fuel injector requires coding or programming to your vehicle's ECU is something we cannot state as fact here, as it depends on your specific engine variant, the generation of your vehicle, and the calibration data stored in the injector itself. This is exactly the kind of question you should put directly to each breaker alongside your engine code and registration, and ideally to a Mercedes specialist who can advise on your specific engine. Do not assume a used injector will be plug and play without confirming this with a qualified mechanic before purchase.
