Fitment questions

Does the Mercedes-Benz B-Class actually have a power steering pump?

Most B-Class models do not have a traditional hydraulic power steering pump — from the first generation (W245, 2005–2011) onward, Mercedes-Benz fitted the B-Class with electric power steering (EPS), which uses an electric motor rather than a belt-driven hydraulic pump. If your steering feels heavy or has lost assistance, the fault is most likely in the electric power steering motor, the steering column, or the EPS control unit rather than a hydraulic pump. A breaker who specialises in B-Class parts will be able to point you toward the correct component for your fault.

I've been quoted a 'power steering pump' for my B-Class — is that the right part?

Almost certainly not — the Mercedes-Benz B-Class uses electric power steering across all generations (W245 2005–2011 and W246 2011–2018), so there is no hydraulic pump to replace. The part you are most likely looking for is the electric power steering motor and column assembly, sometimes listed by breakers as an EPS motor or steering rack with motor. It is worth telling the breaker your exact registration so they can confirm the correct steering component for your specific car.

Could a B-Class from before 2011 have a hydraulic power steering pump that fits my later car?

No — neither the first-generation W245 (2005–2011) nor the second-generation W246 (2011–2018) was fitted with a hydraulic power steering pump, so there is no pump from any B-Class generation to source. Both generations used electric power steering from the outset, meaning the concept of swapping a pump across the 2011 generation boundary does not apply here. If you need steering assistance components, ask breakers specifically for the EPS column or electric steering motor matching your generation and registration.

Does it matter which trim level my B-Class is — Sport, SE, or AMG Line — when sourcing steering parts?

Trim level does not affect the type of steering system fitted — all B-Class variants across SE, Sport, and AMG Line grades use the same electric power steering setup with no hydraulic pump involved. However, since the part you actually need is an electric steering component rather than a pump, you should confirm the exact part with the breaker against your registration, as engine size or minor mid-generation changes could affect the specific column or motor assembly required. Trim differences on the B-Class are largely cosmetic and will not determine which steering component you need.

What should I search for instead of a power steering pump for my Mercedes B-Class?

You should search for an 'electric power steering column', 'EPS motor', or 'power steering rack' depending on where the fault lies on your car — breakers familiar with B-Class (W245 or W246) stock these components rather than hydraulic pumps. If you are unsure which part is faulty, a diagnostic check (reading the EPS fault codes) before contacting breakers will help you order the right item and avoid unnecessary purchases. Give any breaker your full registration so they can match the correct steering assembly to your exact car.
