Hi, Can anyone tell me why sometimes the power steering stops working at low speeds, when parking in bays at supermarket etc. It happens often but not all the time. Engine temp doesn't seem to be relevant as it happens whether its hot or cold. I've got it booked in for a new pump fitting Tuesday 9/6/15 but don't want to go to that expense if it could be something other than the pump. Fluid levels are ok. Thanks in advance
