B1168Steering angle sensor signal fault
- Volkswagen group code · ABS / stability control
- Lights a warning lamp
- How the car detects it
- The ESC unit doesn't get a usable steering-angle signal: no signal, too low a supply voltage or no basic setting (calibration). Audi bulletins for the A3 trace the sporadic version to a voltage drop at the power steering unit during engine start. While it is stored, stability control may be switched off; normal braking still works.

- ESC, ABS or TPMS warnings at start-up
- Likely causes
- PossibleSteering angle sensor needs calibration (after alignment or steering work)
