Note. Text message "Audi Lane Keeping Assist not available: No sensor overview currently available" appears if the camera becomes impossible to operate due to a prolonged lack of clear lane markings. The reasons may be the following: contamination or icing of the camera's field of view (in this case, eliminate the cause); Fogging of the camera's field of view (wait for the fogging to clear); due to road conditions (for example, a snowy road) for a long time it is impossible to distinguish the marking lines.
If fogging does not clear on its own or if there is heavy dirt on the inside of the glass (in the camera's field of view) You must clear the camera's field of view manually. To do this, you need to remove the control unit and the ambient light curtain and clean the windshield with a cleaning solution. For lane assist to work, proper calibration is required. A new calibration is required if: there is an active problem in the memory unit "the basic setting/adaptation is missing or incorrect"; The lane departure warning control unit -J759- is changed; replacing or removing the windshield; rear wheel toe angles are adjustable; changes were made to the vehicle's chassis, for example, replacing the standard chassis with a sports one. The ride height sensors on vehicles with electronic damping control have been retrained.
Note. Before calibrating the lane assist, the fault memory must be read and the faults rectified if necessary. To calibrate the lane assist, you need to determine the direction of movement of the vehicle. will serve as the starting position for the vehicle -IMS 6430-.
