Second Hand Mercedes-Benz A-Class Fuel Injection Pump

This question spans the W169 generation (2004–2012, facelift 2008), so both years sit within the same generation, which is a promising start. However, fitment depends primarily on matching the engine code exactly — a 2.0 CDI pump will not suit a 1.5 CDI, for example — so check your engine code on your V5 or via a VIN check before approaching a breaker. Whether any ancillary or mounting changes occurred around the 2008 facelift that affect the pump is something you should confirm with the breaker against your registration.

The W168 ran from 1997 to 2004 and the W169 from 2004 to 2012, making these distinct generations with different engines and architecture, so a direct swap is very unlikely. Engine codes differ significantly across these two generations, and the fuel injection pump follows the engine, not the body. Always confirm with the breaker against both registrations before purchasing.

Trim level does not affect fuel injection pump fitment on the A-Class — SE, Sport, AMG Line, and Elegance are cosmetic and equipment packages, not mechanical distinctions. What matters is that the engine code, fuel type, and gearbox type on the donor vehicle match your own, regardless of what badge sits on the tailgate. Bear in mind the donor car may have different interior trim or exterior details, but none of that affects whether the pump itself will work.

The engine code is the single most important detail for fuel injection pump fitment — it tells a breaker exactly which variant of petrol or diesel engine you have, which matters far more than the year or model badge. You can find your engine code on your V5 logbook, via a VIN check with a reputable online service, or sometimes on a sticker under the bonnet. Once you have it, pass it directly to the breaker when requesting a quote on Findapart.

No — fuel injection pumps are fundamentally different between diesel and petrol engines and are not interchangeable under any circumstances. Always confirm both fuel type and engine code match between the donor vehicle and your own before agreeing a purchase. A breaker will need your engine code and fuel type as a minimum to quote correctly.

The W176 generation ran from 2012 to 2018 with a facelift in 2015, so a 2012 and a 2014 car both sit in the pre-facelift phase of the same generation, which is a good foundation for compatibility. Fitment still depends on matching engine codes precisely — the W176 was offered with several petrol and diesel units and the pump is specific to the engine, not just the generation. Confirm the match with the breaker against your registration to be sure.
