Audi A3 display screen flickering or showing distorted images may be caused by system issues or a crash due to unstable working voltage of the motherboard. Issues with the vehicle's system: The vehicle navigation system mainly consists of the main unit, display screen, operation keyboard (remote control), and antenna. It enables digital intelligent navigation for field surveys and travel. If there are problems with the vehicle system, upgrading the system may resolve the issue. Unstable working voltage of the motherboard: The motherboard is generally a rectangular circuit board that houses the main computer circuit system, which is an essential component of the vehicle system. Initial troubleshooting can involve restoring the system to factory settings. If the issue persists, it is advisable to visit a repair shop for further assistance.

Last time I drove an Audi A3, I also encountered screen flickering and thought it was a virus. Later, I found out the USB drive plugged in had an incompatible file format, and removing it fixed the issue. This car is particularly picky about high-definition video formats, and transferring files from a dash cam can easily cause screen lag. Another time, after being exposed to intense sunlight, the screen flickered wildly upon startup and only returned to normal after cooling down for half an hour—probably due to heat-deformed wiring causing poor contact. Those who have modified their center console should be extra cautious, as aftermarket reverse cameras with excessive power can overload the system and cause screen flickering. It's recommended to first reboot the infotainment system by disconnecting the power; holding down the volume knob for 10 seconds can resolve 80% of software-related lag issues.
