The power steering makes it easier in principle steering at low speeds and when maneuvering. There are two types of power steering:

  1. Hydraulic Steering
  2. Electric power steering

If it is the electric power steering, the steering supported by an electric motor. In an electric power steering can cause a voltage drop or it is a fuse broken. The workshop then cleans the electrical contacts or changes the fuse. The electric power steering is maintenance-free as a rule.


The hydraulic power steering system is operated via a hydraulic system with oil. In a defective power steering it is exchanged in the workshop.

Cause of a defective power steering

A defect in the hydraulic power steering is often caused by the lack of power steering fluid in the hydraulic system. Especially the high oil pressure in the system of the power steering requires that the material highest demands.

Once the servo oil leaks, the servo pump is dry and the steering is heavy. This also prevents hydraulic oil flows more into the steering gear, which then also dry out. The steering gear is then broken slowly.


Thus, for a defect in the power steering notice Oil loss – a symptom of defective power steering

Additional creaking or whistling noises when turning also suggest a defective power steering. Leaking hoses of hydraulic system lead to oil loss. For example, can the leaked oil on the floor notice under the car or when looking in the oil reservoir of the power steering. Foaming in the reservoir is also indicative of a loss of oil.
