Mercedes-Benz GLB Fuel Filter Replacement Parts

It depends entirely on your fuel type. Diesel GLBs (using the OM654 engine family) have a serviceable fuel filter, typically housed in the engine bay as part of the fuel system. Petrol GLBs use a sealed, in-tank fuel filter that is not a separately replaceable service item and is generally not sold as a standalone used part — if you have a petrol GLB and are chasing a fuel system fault, the component you may actually need is the in-tank fuel pump assembly or fuel pressure regulator, so confirm with your breaker what the fault is pointing to.

The GLB (X247) launched in 2019 and received a facelift around 2023, so both a 2020 and a 2022 car sit within the same pre-facelift generation. Provided both cars share the same diesel engine code — most commonly the OM654 2.0-litre — fitment is likely to be compatible, but you should confirm the exact engine code from your V5 or a VIN check before buying, as ancillary mounting details can vary within a production run. Always confirm with the breaker against your registration to be sure.

The GLB X247 facelift arrived around 2023, and whether a pre-facelift fuel filter crosses that boundary is not something that can be guaranteed here. Name the boundary confidently — pre-facelift 2019–2022, facelift 2023 onwards — but whether the fuel filter assembly changed at that point is something you should confirm with the breaker against your specific registration and engine code, as ancillary and mounting details can change mid-production without a full model revision.

No, the trim level makes no difference to which fuel filter you need on a diesel GLB — Sport, AMG Line, and AMG Line Premium all use the same mechanical fuel system for a given engine. What matters is your engine code and fuel type, not the badge or the interior specification. Do be aware that a used filter from a breaker may arrive with varying bracket or housing colours depending on the donor vehicle, but this has no effect on function or fitment.

The GLB 200d typically uses the OM654 2.0-litre four-cylinder diesel engine, but the exact engine code suffix can vary by market and model year, so the most reliable thing you can do is check your V5 registration document or run a VIN check to get the precise code. Quoting the engine code directly to your breaker is far more useful than quoting the badge name, as mechanical parts follow the engine rather than the marketing name. This ensures the breaker can match the correct filter housing and connections to your specific build.

The GLB 200d and 220d are both diesel models that use variants of the OM654 engine family, but they can have different engine code suffixes reflecting differences in tune and ancillary components. Whether the fuel filter itself is identical across those variants is worth confirming — pull the engine code from your V5 or a VIN check and supply it to the breaker, who can cross-reference it against the donor vehicle's code before shipping. Do not assume fitment based on the badge alone.
