WM 456019 Removing And Installing Steering-Angle Sensor For PSM: Removing

→ When removing and installing the steering column switch, turn the steering wheel so that the wheels are in straight-ahead position. This ensures that the airbag contact unit is locked in the central position.

→ Do not trap the cable of the airbag contact unit.

→ Check that the cable is routed correctly.

Information 

If the airbag contact unit setting was changed accidentally, it must be adjusted. To position the airbag contact unit in the central position, press the locking element and turn the rotor carefully to the left as far as it will go. Then turn the rotor carefully to the right, approx. 3.5 to 3.75 revolutions, until the lock engages. The arrow marking on the rotor must be positioned between the arrow markings on the contact unit.
