Simply turn off the vehicle and shut down the power, then restart the engine. At this point, the display screen will restart. You can also choose the three-button restart function, which involves the 【SETUP】 button, the left rotary button, and the upper right button. Press and hold these three buttons simultaneously to restart.

From my personal experience, don't rush to the dealership when your display freezes. First try the easiest fix: press and hold the center console volume knob for over 10 seconds until the screen goes black and reboots, similar to force-restarting a phone. If that doesn't work, turn off the engine, exit the car, lock it, and wait about 7-8 minutes for a complete system power cycle. This emergency trick saved me when I had a black screen issue before. Later I discovered the 'Restore Factory Settings' option in the instrument cluster menu also works well - just note it'll erase personal settings like navigation favorites. Pro tip: for newer touchscreen models, press the hazard light button + lower-right menu button simultaneously to trigger reboot, while older knob-equipped versions require holding the knob + back button combo.

When I used to drive the old Q5, the display screen would often freeze. Now I've figured it out: hold down the power button with the 'triangle in a circle' on the center console without letting go, and wait for 15 seconds to see it reboot. If it's severely stuck, directly press the physical button combination on the panel below the volume knob (the second asterisk button from the right + the large round button in the middle), which is much more reliable than the touchscreen. I accidentally discovered that turning off the engine and opening the driver's door to cut power for 15 minutes is even more thorough, as it refreshes the car's computer. If the screen freezes frequently, it's recommended to turn off fancy features like 'Cockpit Synthetic View' in the MMI settings to reduce system load. By the way, when applying screen protectors, don't let the technician spray too much water, as moisture can also cause the touchscreen to malfunction.

Once, while driving my child to school, the screen suddenly went haywire. Here's how I handled it: Press and hold the volume-down button (a physical key) on the right side of the steering wheel, while simultaneously pressing and holding the menu button with three horizontal lines in the lower left corner of the center console with your left hand. Hold both for over ten seconds until the logo appears. My friend who drives a touchscreen A6L has an easier method—just press and hold the top-right corner of the screen with two fingers for five seconds. A little extra tip: Pulling and reinserting the No. 42 spare fuse in the trunk fuse box is equivalent to a deep reboot, though women should use this method with caution. Also, don’t leave the screen on when parked and waiting—setting it to automatically sleep after 15 minutes in the settings can reduce the chance of crashes.

A fellow car modder shared some hardcore tricks: For newer models with virtual cockpits, first turn off the ignition, then simultaneously press the brake + start button (don't start the engine) + long-press the center console knob—three steps to enter mode. For older MMI cars, use a toothpick to poke the reset hole of the CD changer in the glovebox, then press the three physical buttons near the handwriting pad to reboot. Important note—before using these hardcore methods, take photos to save data like seat positions and AC settings, as the system will reset to defaults. Actually, aftermarket CarPlay modules are the most prone to conflicts—avoid operating the screen when updating map data.
