How to restart the new A4 MMI system?
4 Answers
For the new Audi models, simply press the virtual rotary controller and the software button in the upper right corner simultaneously to restart the system. Alternatively, you can also press and hold both the left and right arrow buttons on the control panel to complete the operation.
Last time I encountered MMI freezing, I simply held down three buttons on the center console simultaneously: the volume knob, the return button on the multimedia control panel (the one with the square in the middle), and the navigation button in the upper right corner. Hold them for ten seconds without letting go, and once the screen goes black and lights up again, it's done. The whole process is similar to restarting a smartphone, and the system response becomes noticeably faster. Just remember to do this when the car is parked, as attempting it while driving can be distracting. If the system still lags after the restart, it might need an update—just visit the 4S shop to flash the latest firmware. Although the new infotainment system is user-friendly, occasional glitches are inevitable.
Restarting the MMI system on the A4 is actually quite simple, and here's how I often do it: First, locate the volume knob near the gear shift on the center console, then simultaneously press and hold the middle button on the right side of the control panel along with the navigation function key. Hold all three buttons together for 10-15 seconds until the screen completely turns off and then lights up again. This trick can solve most freezing issues and is much more convenient and safer than disconnecting the battery. I recommend performing this proactive restart every two months, just like clearing the cache on your phone. After the operation, check if the offline maps in the navigation need updating, as some personalized settings may revert to default values—simply readjust them as needed.
To restart the MMI in the new A4L, press these three buttons simultaneously: the volume knob with markings on the right, the navigation knob in the upper right corner of the center control touchpad, and the circular menu button in the middle of the operation panel. Hold them down until you see the screen flicker, and keep holding until the screen goes black and restarts. This soft restart won't harm the system and is more reliable than pulling fuses. When using navigation, avoid opening too many background apps; wait until the map is fully loaded before operating other functions to reduce the chance of freezing. If you encounter a black screen, don't panic—just wait two or three minutes, and it will restart automatically.
