NOTE: The power steering pump must be filled
and vented as specified.
The electro-hydraulic power steering pump
comprises a brushless DC motor, the hydraulic
pump and the power steering fluid reservoir.
The hydraulic pump is a gear pump; a resonance
chamber incorporated into the pump body reduces
noise emissions.
The operating pressure is also regulated by means
of a pressure limiting valve which is integrated in
the pump housing. The pressure limiting valve
stabilizes the throughput to the steering gear to a
particular level independently of engine speed.
The pressure relief valve will operate if the
discharge from the pump is restricted, for example, steering held on full lock. If the output from the
pump is blocked, all output is recirculated through
the pump. As no fresh fluid from the reservoir is
drawn into the pump in the process, the
temperature of the power steering fluid in the pump
quickly increases. Consequently, periods of holding
the steering wheel at full lock should be kept to a
minimum to prevent overheating of the pump and
the power steering fluid within it.
The pressure limiting valve limits the pressure on
the outlet side to 120 bar.

The steering angle sensor is a inductive sensor.
The steering angle sensor monitors the steering
wheel position and the rate of turn of the steering
wheel. This information is sent to the power
steering module.
On vehicles built from 09/2009the power steering
module uses the information from the steering angle sensor at the steering column. The required
information is made available to the power steering
module via the CAN bus.

In the electrohydraulic power steering system, a
brushless 12 volt direct current motor drives the
hydraulic pump. Higher pumping rates are only
provided when they are required for steering
manoeuvres. This avoids unnecessary energy
consumption in the majority of phases in a drive
cycle.
Commutation in the motor is done electronically.
As a result, there are no brushes to wear away.
The entire system is designed for maintenance-free
operation.
In more than 85% of all driving situations, the
power steering pump operates at standby speed
and consumes less than 4A. However, pump speed
can quickly increase to full rotational speed if
emergency steering manoeuvres require it. The system has a continuously variable pump
rotational speed.
