Second Hand Mercedes-Benz GLA Fuel Filter

It depends on your fuel type. Diesel GLAs (across both the X156 generation from 2013 and the H247 generation from 2020) do have a serviceable fuel filter, typically integrated into the fuel system and accessible for replacement. Petrol GLAs, however, use a sealed lifetime filter built into the fuel pump assembly inside the tank, which is generally not a separately replaced service item and is not something breakers routinely supply as a standalone part. So if you have a petrol GLA and are looking for a fuel filter, you may actually need a fuel pump assembly instead.

Both of those years fall within the first-generation X156 GLA, which ran from 2013 to 2019 with a facelift in 2017, so you are within the same platform. The key thing to match is the engine code rather than the year, as diesel variants across this generation used engines including the OM607 and OM651 family, and the filter specification can differ between them. Check your engine code on your V5 or via a VIN check and give that to the breaker, as matching on year alone is not reliable enough. The breaker can then confirm whether the specific filter from their vehicle crosses over to yours.

The H247 GLA launched in 2020 as a full new generation with revised engines, so crossing the X156-to-H247 boundary is a significant change and a direct swap is unlikely. The diesel engines used in the H247, such as the OM654 family, differ from those in the X156, and the filter housings and fittings are not the same. You should treat these as separate parts entirely and source a filter matched to your specific generation and engine code. Confirm the exact part with the breaker against your registration to be certain.

No, trim level makes no difference to the fuel filter on a diesel GLA. Sport, AMG Line, Executive, and other trim grades share the same diesel engines and fuel systems within a given generation, so the filter is determined by the engine code, not the badge on the tailgate. The only cosmetic differences you might notice on a part pulled from a different trim are things like bracket colours or cable ties, which are irrelevant. Give the breaker your engine code and generation and they can match the right filter regardless of what trim the donor car was.

The most important detail is your engine code, which you can find on your V5 logbook or by running a VIN check — this tells the breaker exactly which filter housing and specification your car uses, and is more useful than the year or trim level alone. You should also tell them whether your car is the X156 generation (2013–2019) or the H247 generation (2020-onwards), as these are different platforms. Your registration plate will also help the breaker cross-reference their stock quickly. Fuel type is worth confirming too — diesel only, as petrol GLAs do not have a separately serviceable filter.

The X156 facelift arrived in 2017 and brought styling and technology updates rather than fundamental engine changes, so for most diesel variants the fuel filter specification remained the same across pre- and post-facelift X156 cars. That said, whether a specific filter from a pre-facelift donor car is a direct swap onto your 2018 facelift car is something to confirm with the breaker against your engine code, as ancillary mounting or housing details can change mid-production. Matching by engine code is the safest approach here, not just by facelift or pre-facelift status.
