Mercedes-Benz GLA Water Pump Replacement Parts

The GLA X156 generation ran from 2014 to 2019, so both years sit within the same generation, which is a good starting point. However, fitment depends primarily on engine code — a pump from a 2.0 petrol engine will not suit a 2.1 diesel engine regardless of year, so match the engine code from your V5 or a VIN check first. Even within a shared engine code, ancillary and mounting details can change mid-production, so confirm the specific part with the breaker against your registration before purchasing.

The first-generation GLA (X156, 2014–2019) and the second-generation GLA (H247, 2020 onwards) are entirely different platforms with different engine families, so water pumps are not interchangeable across this boundary. Even where engine displacements look similar on paper, the engine codes differ between generations and the pumps are designed to different specifications. Always supply your engine code to the breaker so they can match the correct unit to your exact vehicle.

No — trim level has no bearing on water pump fitment for the GLA. Whether your car is an SE, Sport, AMG Line, or any other trim, the water pump is determined entirely by the engine code, not the badge on the tailgate. Give the breaker your engine code (found on your V5 or via a VIN check) and they can identify the correct pump regardless of trim.

No — petrol and diesel engines in the GLA use completely different water pumps, even where the model year is the same. For example, the 2.1-litre diesel engines (engine codes OM651 family) and the 2.0-litre petrol engines (M270 or M260 family) are entirely separate units with different pumps. Always confirm your exact engine code with the breaker rather than relying on fuel type alone, as there are also variations within petrol and diesel families.

The single most useful detail is your engine code, which you can find on your V5 certificate or by running a VIN check — for a 220d this is typically within the OM651 diesel family, but confirm your specific code as variants exist. You should also provide the year of manufacture and your registration number, so the breaker can cross-reference any mid-production changes to ancillary or mounting specifications. With that information a reputable breaker can advise on compatibility accurately rather than relying on the model name alone.

Not necessarily — while both are petrol variants, the GLA 200 and GLA 250 use different engine outputs and may carry different engine codes, which directly affects which water pump fits. In the X156 generation, for example, both drew from the M270 engine family but in different states of tune, and pump specifications can vary even within the same engine family. Confirm your specific engine code with the breaker, as that is a more reliable guide than the badge number on the car.
