The couple of times it was as if the steering locked for a fraction of a second and there was an audible clunk from the steering column. A loose connection was blamed on it's first visit to the service department a fault within the steering column the second. Last weekend went to reverse out of a parking space and the power steering failed, I pulled back into the space and switched off the engine. As it was after midnight and I was in a station car park on my own I tried again and there wasn't a problem. I booked it in with my dealer for when I was back home but yesterday it failed again but this time the fault lights lit up. We got onto the service manager at our dealership and he advised us to have the car recovered.
