WARNING: Steering-angle sensor not calibrated or calibrated incorrectly

Unexpected vehicle handling
Steering-angle sensor does not function
Malfunction in steering-angle sensor
- After working on wheel suspension parts, when replacing the steering-angle sensor, and after changing the wheel alignment values, calibrate the steering-angle sensor using the PIWIS Tester .
- Keep the front wheels in straight-ahead position on the measuring platform during calibration.
- For vehicles with electromechanical steering, also re-teach the electric steering lock settings.

If the previous wheel alignment values (on rear and/or front axle) were changed, the following subsequent work must be performed:
