I think I have a power steering problem with the 80. It has been driving fine the past week, but I noticed on the weekend, the steering worked fine, until it was under heavy steering. ie driving slowly to park or turn onto the drive. It starts off whining, but with further pressure turns into an awful grinding type of sound. As soon as you let the steering go or whilst driving normally, its fine. With the horrific weather we had yesterday, I noticed our the rain water on our driveway had an oily sheen to it. I've checked the car today in the underground office car park and it is definately leaking green fluid. I haven't had a chance to get under the car to see if I can find the source to my problem, but I was wondering whether anybody had any ideas?
