Second Hand Mercedes-Benz A-Class Fuel Injector

These are two completely different generations — the W176 ran from 2012 to 2018 (facelift 2015), and the W177 began in 2018 — and the injectors are not interchangeable across that boundary even if the engine displacement looks similar on paper. The engine code stamped on your V5 or confirmed via a VIN check is the detail that matters most, and you should give that to the breaker so they can match precisely. Never assume a W176 injector will drop into a W177 without the breaker confirming it against your registration.

Both the 2013 and 2016 A-Class are within the W176 generation (2012–2018), with the facelift arriving in 2015, and injectors from the same engine code within that generation are often compatible — but ancillary or mounting changes can occur mid-production even within the same generation. Supply your engine code to the breaker and ask them to confirm against your registration before purchasing, as a facelift year can occasionally bring running changes the badge alone won't reveal.

Yes, fuel injectors are fitted to all A-Class variants regardless of fuel type, but the type of injector differs significantly — petrol engines use direct or port fuel injectors while diesel engines use high-pressure common-rail injectors, and these are not interchangeable at all. Your engine code (for example M270 for a 2.0 petrol or OM651 for a 2.2 diesel in the W176 generation) tells the breaker exactly which injector family is required. Always state your fuel type and engine code when requesting a quote.

The badge or trim designation (A180, A200, A220 and so on) matters only insofar as it typically signals a different engine code, and it is the engine code itself — not the badge — that determines injector fitment. Two cars badged A200 built in different years could carry different engine codes, so never rely on the badge alone. Give the breaker your engine code from the V5 or a VIN check, and the badge becomes a secondary detail.

No, trim level has no effect on fuel injector fitment whatsoever — AMG Line, Sport, and SE are cosmetic and equipment packages, not mechanical variants. The injector is determined entirely by your engine code and fuel type, so a breaker sourcing an injector for an AMG Line car and an SE car with the same engine code will be looking at the same part. The only cosmetic difference you might notice on a used injector is general wear, which has nothing to do with the trim the donor vehicle came from.

Some Mercedes-Benz fuel injection systems do store injector-specific calibration data, and whether a used injector will require coding or adaptation to your vehicle's ECU is something you should confirm with the breaker and your fitting garage before buying. This is particularly relevant on later common-rail diesel systems and some direct-injection petrol units where injector coding values are programmed at manufacture. A good breaker will often be aware of this, but the fitting specialist carrying out the work is best placed to advise on what your specific engine code requires.
