Why does the Audi A4 screen go black by itself?

Audi A4 display black screen has two reasons: vehicle linkage or battery problems. Detailed explanation is as follows: 1. Vehicle linkage: It may be disconnected, unable to connect to the power supply, poor contact, intermittent lines preventing proper discharge, and the device cannot connect. In this case, you should go to a vehicle electrical repair center or a professional auto repair shop for repair. 2. Battery problem: It may be due to cold weather, causing the battery to not supply power properly. Insufficient memory or other reasons may cause the host to freeze, memory capacity filled with garbage or memory full, and the screen freezes and cannot operate normally. In this case, you can press the start button on the host to turn it on.
Oh man, I've also encountered the black screen issue with my Audi A4, and it's really frustrating. It usually happens suddenly after prolonged driving—the screen goes completely black while the audio system still works. Some mechanic friends told me it's mostly caused by software bugs, like system incompatibility after updates or app crashes. Hardware issues could also be the culprit, such as the screen backlight overheating and triggering the protective circuit to shut down, or loose wiring connections that cause the screen to black out when driving on bumpy roads. I've tried solutions like parking, turning off the engine, waiting 5 minutes for the system to cool down, and then restarting—sometimes that works. But if it happens frequently, don't push your luck—just take it to the dealership for a check. This issue affects navigation and safety features like the reversing camera disappearing, which can be dangerous. Usually, try not to overload the infotainment system and give it more shutdown breaks.
Black screen issues are quite common in the Audi A4, primarily stemming from both software and hardware aspects. On the software side, it could be due to infotainment system bugs or conflicts, such as crashes during navigation or Bluetooth connections; or background processes getting stuck and consuming resources. Hardware-wise, the screen module itself might be faulty, with components like the backlight aging; loose wiring terminals, especially when vibrations from poor road conditions cause disconnections; or unstable power supply, where low battery voltage triggers protection mechanisms. It's recommended to first attempt a forced restart: hold the volume control button for about 15 seconds to see if a reset occurs. If there's no improvement, check if the vehicle's fuses have blown. Don't overlook this issue, as a black screen also disables the reverse radar, increasing driving risks. Regular diagnostics of wiring and firmware updates at professional shops are crucial.
