What does this fault code mean?
The steering angle is changing faster than the sensor accepts, which sets the code and blocks the stability function. The probable cause is that the wheels have hit something such as a kerb, although an internal fault in the control module is also possible.
Possible causes
- Wheels have struck something such as a kerb
- Internal fault in the sensor control module
What you can do
- 1Read and note the code, clear it and road test to see whether it returns
- 2Look for damage to the front wheels and rims after a kerb strike or stone impact
- 3Check whether the front wheel alignment has changed, and ask a workshop to check it if you are unsure
- 4The stability function stays blocked while the fault is present, so have a workshop repair it promptly if it returns
