BMW E65 steering angle sensor fault
E65 indicator does not self-cancel and traction control does not work - what is the fault?
The cause is often the steering angle sensor module under the steering wheel. When it does not supply steering angle data, indicator self-cancelling, traction control and stability control stop working, and a Drive control system warning may appear on the display.
When does a steering angle sensor fault usually show up?
The symptom often appears in hard frost or after moisture, and it can disappear when the car is restarted. In frost, a weak battery can also cause the same fault messages, so check the battery before replacing parts.
How is the steering angle sensor repaired?
If the fault continues or gets worse, the sensor or module is replaced. It is worth trying to clean the sliding surface first, but it does not always help. The new part must be coded to the car. Some generic diagnostic tools can do the coding, while others need BMW's own equipment.
