Mercedes-Benz GLA Washer Motor Replacement Parts

The GLA has two main generations: the first-generation X156, produced from 2013 to 2019 with a facelift around 2017, and the second-generation H247, which launched in 2020 and is still in production. The washer motor is a genuine part on the GLA, handling windscreen and rear screen wash, so generation matters — X156 and H247 motors are not the same unit and will not interchange. When sourcing from a breaker, confirm your generation by checking your registration against the X156 or H247 body code.

Both a 2016 and a 2018 GLA fall within the first-generation X156, so they share the same fundamental platform and the washer motor should be compatible. The 2017 facelift was largely cosmetic and did not change the washer system, so pre- and post-facelift X156 motors are generally interchangeable. That said, confirm with the breaker quoting you that the part number matches your registration, as minor running changes can occur within a generation.

Trim level does not affect washer motor fitment on the GLA — whether your car is a base SE, Sport, AMG Line, or Executive, the washer motor is the same unit within a generation. There are no trim-specific wash system variations on this model, so you do not need to filter by trim when searching. Simply match the generation (X156 or H247) and confirm front or rear motor, as these are separate parts.

No, the front and rear washer motors are separate units — the front motor sits in the washer bottle reservoir in the engine bay, while the rear motor is a smaller pump, often attached to the same reservoir or mounted separately, dedicated to the rear screen jet. Always specify to the breaker whether you need the front or rear pump, as they differ in design and connector, even though they may share the same reservoir on some variants. Quoting your registration will help the breaker identify the correct unit quickly.

The X156 and H247 are entirely different platform generations, so a washer motor from the older model is very unlikely to be a direct fit on the newer one — mounting points, connectors, and reservoir designs changed between generations. You should not assume cross-generation compatibility, and any breaker claiming otherwise should be able to confirm matching part numbers against both registrations. Stick to sourcing an H247-generation motor if your GLA is a 2020 or later model.

Engine choice makes no difference to washer motor fitment on the GLA — the wash system is identical across petrol and diesel variants within the same generation. Whether your car is a 180, 200, 220 d, or any other engine variant, the washer motor is the same part, so you do not need to filter by engine when asking breakers for a quote. Focus instead on confirming the generation (X156 or H247) and whether you need the front or rear pump.
