What causes the sudden display of automatic headlight malfunction in an Audi?

[SanCorey]

It could be due to dirt on the sensor area, which can often be resolved by washing the car. Automatic headlights function by detecting changes in external light intensity to control the automatic activation or deactivation of the headlights. Below are the specific methods for operating car lights: 1. Turn signals and parking lights: Simply rotate the control lever to the corresponding turn or parking light position while the ignition switch is on to activate the respective lights. 2. High beams: Push the light control lever forward to activate the high beams. 3. Fog lights: The switch is located on the left side of the dashboard; rotate the switch to the appropriate position to turn them on. 4. Automatic headlights, low beams, and position lights: When the AUTO indicator on the button is lit, it means the automatic headlights are active. Rotate the knob to switch between automatic headlights, low beams, and position lights. 5. Headlight cleaning: With the headlights on, activate the windshield washer switch to clean the headlights. If you only want to clean the windshield, turn off the headlights before activating the windshield washer switch.
