Used Mercedes-Benz EQB Power Steering Pump

No — the EQB is a fully electric vehicle and has never been fitted with a hydraulic power steering pump in any variant or trim level. Electric vehicles use electric power steering (EPS), which is controlled electronically and requires no pump, fluid reservoir, or associated pipework. If your steering assistance has failed, the fault is likely within the EPS motor, steering column module, or associated control electronics rather than a pump. You may want to search for an EPS steering rack, steering angle sensor, or speak to a breaker about the specific steering column assembly for your EQB.

Because the EQB uses electric power steering, the component you most likely need is the electric power steering rack and motor assembly, sometimes listed by breakers as an EPS rack or steering rack with motor. You might also need the steering control module or steering angle sensor if the fault is electronic rather than mechanical. When contacting a breaker, quote your full registration so they can match the correct steering assembly, as software calibration and sensor configuration can vary.

There is no power steering pump on the EQB to fail, as it uses a fully electric steering system with no hydraulic components at all. Heavy steering or a steering warning light on an EQB will point to a fault in the EPS motor, the steering rack assembly, a steering angle sensor, or a control module issue. A breaker supplying a used steering rack or EPS assembly for the EQB will need your registration to confirm the correct part, as software variants may apply.

Trim level does not affect which electric steering system was fitted to the EQB, so an EPS rack from an AMG Line car is not inherently different from one fitted to an Advanced or Sport model on that basis alone. That said, always confirm with the breaker against your registration, as build-date or market-specific differences in the steering electronics could exist. Cosmetic differences between trim levels — such as bodywork or interior finish on a donor car — are irrelevant when sourcing steering components.

No other power steering pump will fit the EQB because the EQB does not use hydraulic power steering at all — there is no pump, no fluid lines, and no reservoir on any version of this vehicle. Fitting a hydraulic pump from another Mercedes is not applicable and would serve no purpose. If you need steering assistance components for the EQB, you need parts specific to electric power steering systems, and a breaker should be asked to match EPS parts to your exact registration.
