A few days ago my Nissan's PS light came on when I started it up and the steering was very heavy and I have been unable to drive it. I had it towed to my local garage and after investigating they are reporting that the Power steering pump has gone and needs replacing. This would be at a cost of £1300. new or possibly if they can get hold of one £350+VAT. Right now this is an expense I really cant manage (either price) and am not really sure that they have rightly diagnosed. Can any one make any suggestions?Does this sound right? I am in the london area(North East) . Any advice will be much appreciated!
