Should the active lane assist experience a fault, the indicator lamp in the instrument cluster display will go out and one of the following messages will appear:
Audi active lane assist: currently unavailable. No camera view
This message is displayed when the camera is no longer functional after the system has continuously failed to detect the lane markings. This can have the following causes:
  • The outside of the camera window Fig. 3 is dirty or frosted. Remove dirt or ice from this area of the windscreen.
  • The inside of the camera window is misted up. In this case, wait for the camera window to demist before switching on the active lane assist system again.
  • Due to the road conditions, the system has not been able to detect the lane markings for a long period. Do not switch the active lane assist system on again before the lane markings are discernible.

A temporary fault is preventing the active lane assist system from functioning. Try switching on the active lane assist system again later.
Audi active lane assist: system fault!

Audi active lane assist: please continue steering vehicle
This message will appear if you do not steer the vehicle yourself. In this case, the active lane assist will switch to "not ready for warning" but will not be deactivated completely. The system can assist you to keep the vehicle in the lane. However it is your own responsibility to steer and control the vehicle.
