We had a 2001 Mercedes-Benz that had burned the power steering pump. The problem in fact was that the car was loosing 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 that there was 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.

Below is a quick overview on how to change the power steering line on a Mercedes-Benz E-Class, W210.

Instructions

  1. Jack up the vehicle and secure it with jack stands.
  2. Drain the power steering fluid form the reservoir. You will have to suck it out with a syringe or similar.
  3. Remove the 17mm bolt at the power steering pump.power steering line
  4. Get under the car to access the other end of the line. You will be right below the driver's footwell. Be careful because there are two lines here that go to the power steering rack. The bolts are very close and you may take off the wrong bolt.power steering line bolt leak

     

  5. Disconnect the wire harness if necessary to make more room. power steering line
