Power Steering Problems.
I have a Mini Cooper on a 53 plate and the power steering is causing me problems. Basically when the engine is relatively cold the power steering is ok when you start the car, but once the engine is hot and you turn the engine off and start it again, the power steering does not work. then if you leave it to cool down for about 30mins. and try again the power steering works again. not once has the power steering failed whilst driving the car, only when the engine is turned off and started again, say when you go for petrol. Do I need a new motor or is it something else?
