Hi John
Thanks for you response. My daughter says she was driving and she heard the steering wheel lock, she was going down a hill in third gear and the engine cut out. She managed to stop vehicle, restarted car and had to move steering wheel to take lock off. This is the 3rd time this has happened now in 12 months. It is going to be looked at tomorrow but our mechanic hasn'ty got a clue so is taking it to a Ford specialist.
Any bright ideas?
