Do some reading but I'm guessing you need a new/replacement power steering control module.
It is located near the battery on left hand drive vehicles.

Keep in mind a NEW module will need calibrated using software. A used unit has been known to work fine just installing it and reconnect the battery.

 

Thank You i will buy one and will give a review
