What happens

Symptom. A steering warning light, a message about the active steering, and in some cases a stiffer or unpredictable rack response.

Cause. Where active steering was optioned, the actuator and its control unit can fail. Cars without the option are unaffected, so establish which system the car has before pricing the risk.

How to check it

Cold start

Check for a steering warning at start-up, turn lock to lock while stationary, and confirm from the options list whether active steering is even fitted.

You get one. If the engine is warm when you arrive, come back another day.

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.
