We had a 2001 Mercedes-Benz that had burned the power steering pump. The problem was that the car was losing power steering and needed to be topped off every week.

Well, eventually, the power steering pump burned, and it needed to be replaced. While replacing the power steering pump, we noticed a large leak in the high-pressure line of the PS pump. You could see a stream of power steering fluid as you moved the steering wheel.
