Attaches to R56 at chassis level · Suspension · carried by 3 variants across 1 chassis
Overview
Electric power steering pump failure is a common fault recorded against R56 at chassis level, typically from 90–180k km. It shows up as steering that goes heavy without warning, a warning light, and a cooling fan for the pump that runs constantly. Where it's documented, the repair runs €450–€1,100 (pump and fan at an independent, with coding, costs dated 2026-07), and it can be checked before you buy. 3 variants across 1 chassis in this database inherit it.
What happens
Symptom. Steering that goes heavy without warning, a warning light, and a cooling fan for the pump that runs constantly.
Cause. The pump sits low at the front of the car where it takes water and road salt, and its electronics fail. A blocked or dead cooling fan brings the failure forward, which is why the fan is worth checking on its own.
How to check it
Static checks
Turn the wheel lock to lock while stationary and feel for any heaviness or hesitation. Listen for the pump fan running at idle, since a fan that never stops is a pump working too hard.
Engine off, ideally on a lift.
Every variant that carries this
| Variant | Chassis | Body | Years | Risk | Good buy | Cost as % of good buy |
|---|---|---|---|---|---|---|
| Cooper N12 | R56 | hatchback | 2006–2010 | R4 | €4,200 | 18% |
| Cooper S N14 | R56 | hatchback | 2006–2010 | R4 | €5,500 | 14% |
| Cooper D N47 | R56 | hatchback | 2010–2013 | R3 | €6,300 | 12% |
The last column is the point. The same repair is an inconvenience on one variant and a reason to scrap the car on another. A failure costing a quarter of the vehicle's value changes the purchase decision regardless of how rare it is.
