A few weeks ago I sent you an email regarding the curious sensation on my Mazda steering, which only occurred after I had driven a few miles and I assumed was temperature related. I have since had the car serviced at a Mazda outlet and mentioned the steering. When I collected the car I was told they had driven the car and found nothing wrong. However, since then, on a few occasions when driving very slowly, such as driving into my garage, the power assistance has disappeared such that the steering wheel can hardly be turned. I found that by increasing the engine revs, the power assistance returned.

Obviously something is wrong and I propose taking the car to a garage for it to be sorted. However, if you have any thoughts as to what it could be I would be very grateful for your views, as I don’t like going to a garage without some idea as to what the problem is?
