The steering gear is mounted on the front axle
crossmember and is secured with two bolts. The
bolts are inserted in the steering gear from above
and screwed into the threaded lugs on the front
axle crossmember.
The following components can be renewed
separately or as a unit:
• Complete steering gear
• Steering gear rubber bushes
• Tie rods.
• Steering gear boot
• Tie-rod end
• Steering angle sensor - vehicles built up to 09/2009 During removal and installation or renewal of
components of the steering gear, pay attention to
the following: (excluding steering angle sensor)
• Before undertaking repair work on an accident
damaged steering gear, the scope of the repair
must be determined using the inspection
instructions "Steering gear inspection after an
accident". For additional information, refer to
"Diagnosis and Testing" in this section.
• When the steering gear is removed and installed, the front axle crossmember must be
aligned with the bodywork using the appropriate
special tools.
• After completing the work, the suspension geometry of the vehicle must be checked and
corrected as necessary.

During removal and installation or renewal of
components of the electro-hydraulic power steering
pump, pay attention to the following:
• Before starting work to renew the electro-hydraulic power steering pump, the
program code of the electro-hydraulic power steering must be read out using the diagnostic
unit and noted.
• After the work to renew the electro-hydraulic power steering pump is completed, the
electro-hydraulic power steering must be
reconfigured using the diagnostic unit. For
further information, see: Module Configuration
(418-01 Module Configuration, General
Procedures).
• The electro-hydraulic power steering pump must be filled and vented as specified.

System Operation
Electronic principle of operation
The power steering module requires the following
information in order to ensure precise steering
behavior in all driving situations:
• Steering wheel position
• Rate of turn of the steering wheel
• Vehicle speed
• Information about the vehicle configuration
• Information about the ignition switch position
• Instantaneous engine operating status
The required information is made available to the
power steering module via direct connections and
via the CAN bus (refer to the flow chart).
The steering wheel position and the rate of turn of
the steering wheel are transmitted to the power
steering module as PWM signals from the steering
angle sensor. The steering angle sensor receives
its voltage and ground supply from the power
steering module and operates inductively with an
input voltage of 5 V.
The vehicle speed is made available to the power
steering module as a CAN bus signal from the ABS
module or ESP module. The engine operating status is made available to
the power steering module as a CAN bus signal
from the PCM.
The power steering module obtains the vehicle
configuration information via the CAN bus from the
GEM. This information is required by the power
steering module in order to define the internal
characteristics of the power steering.
The power steering module obtains information
about the current ignition switch position via the
voltage input (terminal 15) of the ignition switch.
Whilst constantly monitoring the relevant input
signals the power steering module accesses stored
maps. With the aid of this information the pump
speed is matched to the current driving situation.
An electronic diagnosis of the electro-hydraulic
power steering can be performed with the aid of a
diagnostic tester via the DLC of the vehicle. For
additional information please refer to "Diagnosis
and Testing" in this section.
