Removing and Installing Steering Angle Sensor
WM 456019 Removing and installing steering-angle sensorGeneral information
The steering-angle sensor is integrated into the steering column switch.
The steering angle is recorded in the contact unit for airbags (spiral spring) -C-. The sensed data is sent from the electronic unit -E- via the drive CAN bus to various systems (e.g., PSM, corner-sensitive headlight) for further processing. Replacement of the steering-angle sensor requires the steering column switch to be removed.
If faults have been diagnosed on the steering-angle sensor, the steering column switch must be disassembled into the components -A, B, C, D, E-.
The steering-angle sensor can only be replaced together with the contact unit for airbag -C- (spiral spring) and the electronic unit -E-.
A - Direction indicator switch
B - Cruise control switch
C - Contact unit for airbag (spiral spring)
D - Switch for wiper/washer system
E - Electronic unit
Replacing the steering-angle sensor

1. In order to replace the steering-angle sensor, the contact unit for airbag -C- and the electronic unit -E- must be replaced. (Removing and installing steering column switch includes disassembly and assembly).
2. Once installed, the steering-angle sensor must be calibrated for the PSM system using the Porsche System Tester.
