Cheap Peugeot 508 Power Steering Pump

The Peugeot 508 uses electric power steering (EPS) across all variants of both generations, meaning there is no hydraulic power steering pump fitted to any 508 at any point in its production. If you are searching for a power steering pump, you may be thinking of the electric power steering rack or the EPS control module, either of which can fail and are the more likely parts you need. It is worth double-checking your fault symptoms or diagnostic codes to confirm which component is causing the issue before contacting a breaker.

Because the 508 has electrically assisted steering with no hydraulic pump, a power steering fault will typically point to the electric power steering rack (which contains the motor and torque sensor), the EPS ECU, or occasionally the steering column assembly. A diagnostic scan using equipment such as a Peugeot-compatible reader (e.g. Diagbox) will usually identify whether the fault is in the rack itself or the control electronics. Ask your breaker for the electric power steering rack or EPS module rather than a pump, and give them your registration so they can confirm the correct unit.

The first-generation 508 ran from 2011 to 2018 (with a facelift in 2014), while the second-generation 508 is an entirely different platform launched in 2018, so the two generations are not compatible. Even within the first generation, whether a pre-facelift and post-facelift rack interchange is something you should confirm with the breaker against your exact registration, as electronic steering calibration and connector types can vary. Always give the breaker your full registration to cross-reference the part before purchasing.

Trim level alone - whether your car is an Active, Allure, GT, or any other specification - does not affect the power steering rack fitment on the 508. What matters more is the generation (first-gen 2011-2018 or second-gen 2018 onwards) and engine variant, as different drivetrains can influence steering system calibration. Trim differences are mostly cosmetic, so do not be concerned if the rack from a base-spec car looks identical to one from a higher trim; confirm the part number with the breaker against your registration to be sure.

Engine size and type can influence the steering rack specification on the 508, particularly because heavier or higher-powered variants may use a rack with different assist characteristics or connector mapping. For this reason, it is best to tell the breaker not just your model year and generation but also your engine (for example 1.6 THP, 2.0 BlueHDi, or 2.2 HDi) so they can check the part matches. Do not assume a rack from a 1.6 diesel will be a straight swap into a 2.0 diesel without checking first.

The 508 SW (estate) body style shares its platform and powertrain with the saloon and, on the second generation, the fastback, so the power steering rack is likely to be the same unit across body styles within the same generation and engine variant. However, because the EPS system is electronically calibrated, you should confirm compatibility with the breaker using both registrations rather than assuming a straight swap. If the part numbers match and the engine and generation align, body style on its own is unlikely to be a barrier to fitment.
