Second Hand Mercedes-Benz GLB Power Steering Pump

No — the GLB (X247), launched in the UK in 2020, uses an electric power steering (EPS) system, meaning there is no hydraulic power steering pump fitted to any variant of this model. If your steering assistance has failed, the fault is most likely in the electric power steering motor, the steering column assembly, or the associated control module rather than a pump. You may want to search for the electric power steering motor or steering rack instead, and confirm with a breaker exactly which component your system needs.

Because the GLB relies entirely on electric power steering with no hydraulic pump, heavy or failed steering assistance typically points to the EPS motor integrated into the steering column or rack, or a fault in the steering control unit. A used steering column assembly or electric power steering rack from a matching GLB (same generation, same engine variant) is more likely to be the correct part to source. Confirm the specific failed component with a diagnostic scan before approaching a breaker, as the fault code will tell you whether it is the motor, the column, or the control module.

No older hydraulic power steering pump will fit a GLB because the GLB has no hydraulic system at all — there are no fluid lines, no reservoir, and no provision for a pump in the engine bay. Fitting a hydraulic pump from a different model would not be possible without a full system conversion, which is not a practical or cost-effective repair. The correct approach is to source an electric steering component matched to your GLB's specification from a breaker.

Trim level does not determine the type of steering system on the GLB; all variants use electric power steering regardless of whether the car is a Sport, AMG Line, or AMG Line Premium. The steering rack or column assembly you source should be matched on generation and engine variant rather than trim, though you should confirm with the breaker against your registration that the part number aligns with your specific build. Cosmetic differences between trims will not affect the mechanical steering components.

For the electric steering motor or rack, engine variant is less critical than it would be for brakes or driveshafts, but it is still worth confirming against your registration because calibration and software can differ between petrol, diesel, and plug-in hybrid (250e) variants. A breaker should be able to match the part using your VIN to ensure the correct specification. Never assume a part from a different powertrain variant will be a straightforward swap without that check.
