Second Hand Mercedes-Benz GLS Power Steering Pump

Most GLS models use an electric power steering (EPS) system rather than a hydraulic pump, meaning there is no traditional power steering pump fitted. If your GLS has lost power steering assistance, the fault is more likely to be an electric power steering motor, steering column module, or associated control unit. Check your exact variant with a breaker or Mercedes specialist before ordering any pump, as you may be looking for a completely different component.

The GLS has been sold in two main generations: the first-generation X166, produced from 2016 to 2019, and the second-generation X167, which launched in 2019 and remains current. Both generations were designed around electric power steering across the range, so neither generation typically carries a hydraulic power steering pump. Regardless of which generation you own, if you believe a pump is faulty, confirm with the breaker against your registration before purchasing any part.

This question spans the X166 to X167 generation boundary, but in practice the GLS does not use a hydraulic power steering pump in either generation, so there is no pump to swap between the two. If a steering component is needed, the correct part will depend on whether you need an EPS motor, steering rack, or control module, and these do differ significantly across that generation change. Confirm exactly what component you need with a breaker, quoting your registration, before searching for parts.

Trim level does not affect power steering pump fitment because the GLS does not use a hydraulic pump in any trim, including standard, AMG Line, or full AMG 63 variants. The AMG 63 does carry a more powerful engine and uprated steering tune, but the power steering system remains electrically operated throughout the range. If you need a steering-related part on an AMG 63, confirm with the breaker that any component is sourced from the correct AMG variant, as higher-performance models can carry different steering hardware.

Depending on your symptoms, the part you actually need is most likely an electric power steering motor or actuator, a steering angle sensor, the EPS control module, or potentially the steering rack assembly itself. Loss of assistance, heavy steering, or warning lights on the GLS are almost always traced back to the electric system rather than any hydraulic component. A breaker or Mercedes specialist can identify the correct part if you provide your registration and describe the fault.
