Dualdrive Electric Power Steering Column Failure
SeriousSteeringThe Punto Mk2 was one of the first mass-market cars to feature column-mounted Dualdrive electric power steering. The torque position sensors inside the steering column, or the solder joints on the integrated electric motor relay circuit board, suffer micro-fractures over time. This causes the steering assistance to cut out abruptly while driving, illuminating the red steering warning light on the instrument cluster and suddenly reverting the wheel to heavy manual steering.
Steering suddenly becomes excessively heavy while parking or navigating roundabouts, Red steering wheel warning light illuminated permanently or intermittently on the dashboard, Noticeable shudder or vibration through the steering rim when turning past centre
- Turn the ignition on, start the engine, and engage 'City' mode button; turn wheel rapidly from lock to lock several times to check for sudden cutoff
- Switch the engine off and restart to see if any latent steering warning light appears
- Ask if the steering column has already been replaced with an upgraded reconditioned unit featuring optical sensors
