Cheap Mercedes-Benz A-Class Fuel Tank

This is a generation boundary question: the W169 A-Class ran from 2004 to 2012, so both years sit within the same generation, which is a good starting point. However, fitment still depends primarily on engine code and fuel type — a petrol tank won't suit a diesel car even within the same generation. Confirm the engine codes on both vehicles match before purchasing, and ask the breaker to verify against your registration to rule out any mid-production ancillary or mounting changes.

The W169 A-Class received a facelift in 2008, so a pre-facelift tank (2004–2008) and a facelift tank (2008–2012) may appear similar but could differ in fittings or ancillary connections introduced at that point. Engine code and fuel type remain the primary fitment factors, but crossing a facelift boundary introduces enough uncertainty that you should confirm compatibility with the breaker against your specific registration rather than assume it will swap straight over.

Trim level — whether that's SE, Sport, AMG Line, or any other — does not affect fuel tank fitment; the tank is a mechanical component determined by engine code, fuel type, and gearbox type, not by how the car is badged or equipped. You may find cosmetic or ancillary differences in how parts are presented by the breaker, but the trim name itself is not a meaningful fitment variable. Focus on matching the engine code from your V5 or a VIN check, and share that with the breaker when requesting a quote.

These are different generations — the W176 ran from 2012 to 2018 and the W177 replaced it from 2018 onwards — so a straight swap cannot be assumed and is very likely incompatible. Fuel tanks are generation-specific in their overall dimensions and mounting arrangements, and the platform change between W176 and W177 makes cross-generation fitment particularly unlikely. Confirm the exact engine code on both vehicles and raise this directly with the breaker before purchasing.

No: petrol and diesel fuel tanks are not interchangeable, as they differ in filler neck design, sender unit calibration, and sometimes capacity. Always match the fuel type exactly, and make sure the engine code you supply to the breaker confirms whether your car is petrol or diesel — this is the single most important detail after identifying the generation.

The most useful thing you can provide is the full engine code, which appears on your V5C or can be retrieved via a VIN check — this tells the breaker far more than the year or badge alone. Also state your fuel type (petrol or diesel), gearbox type (manual or automatic), and the year of your car so the breaker can place it within the correct generation: W168 (1997–2004), W169 (2004–2012), W176 (2012–2018), or W177 (2018 onwards). With those details, a good breaker can cross-reference their stock accurately and advise on any fitment caveats specific to your registration.
