Mercedes-Benz EQS Washer Pump Replacement Parts

Yes, the EQS does have a windscreen washer pump — despite being a fully electric vehicle with no combustion engine, it still has a conventional windscreen wash system with a pump, reservoir, and jets, just like any other car. The absence of an internal combustion engine makes no difference to the wash system. So if yours has failed, a used washer pump from a breaker is a perfectly sensible thing to search for.

The EQS (Z297 platform) launched in 2021 and has remained within the same generation throughout production, so a pump from a 2021 car may well be compatible with a 2023 car. That said, Mercedes introduced a facelift for the EQS during the 2024 model year, so whether any detail changes affected the washer pump fitment around that point is worth confirming with the breaker against your exact registration. For cars clearly within the same pre-facelift build window, the chances of compatibility are good but never guaranteed.

No — the electric drivetrain variant (single motor, dual motor, or 4MATIC) does not affect windscreen washer pump fitment, as the wash system is entirely separate from the powertrain. A pump from an EQS 450+ and one from an EQS 580 4MATIC should be the same part, provided the cars are from the same generation. Focus instead on the build date and whether the car is pre- or post-facelift, and confirm with the breaker using your registration to be safe.

Trim level does not affect washer pump fitment — the pump and reservoir assembly is the same regardless of whether the donor car was a standard EQS or an AMG Line specification. You may find cosmetic differences around the bonnet area or washer jet covers between trims, but the pump itself is interchangeable. If you are replacing just the pump motor rather than the full assembly, trim is irrelevant entirely.

The EQS is a large saloon-style fastback and does not have a rear wiper or rear wash system, so there is only one washer pump to consider — the front one. If you are being quoted for a 'rear washer pump' for an EQS, that is worth querying, as this part does not exist on the car. Make sure you and the breaker are aligned on exactly which pump is needed.

Give the breaker your full registration number, as this allows them to confirm the exact build date and specification of your car and match it accurately to their stock. It is also worth clarifying whether you need the pump only or the full reservoir and pump assembly, as breakers sometimes sell these together. Since the EQS generation boundary sits around the 2024 facelift, flagging whether your car is pre- or post-facelift can help speed up the process.
