On the left side of the multifunction steering wheel, there is a small button. Pressing it can turn on the sound for the CD player, and pressing it again can mute the CD. Try pressing the volume button or knob continuously. If that doesn't work, check if the sound is turned off in the vehicle settings menu.

Just now, my Volkswagen audio system also had no sound, but the solution is actually quite simple. First, check if there's a speaker icon with a slash on the steering wheel or center console—you might have accidentally pressed it while driving. Press it again to unmute. If that doesn't work, try turning the large volume knob on the center console clockwise to increase the volume. I've also noticed that when connected via Bluetooth, if the phone volume is set to the lowest, the car audio will have no sound, so check both sides. If none of these work, you can force restart the system by holding down the center console power button for 10 seconds, just like restarting a frozen phone. Regularly updating the car's system software is important, as older versions can have bugs causing sudden muting. If all else fails, visit the dealership for a system reset—sometimes, car systems need professional maintenance, just like phones.

I've encountered the sudden muting of the audio system several times. The most common mistake is accidentally pressing the mute button in the media control area on the left side of the steering wheel—just press it again to resolve. Secondly, remember to check the source selection interface; sometimes switching to a Bluetooth channel without music playing can cause silence. Here's a lesser-known fact: Volkswagen models automatically reduce media volume when reversing. If the radar gives a false alarm, the audio system might think it's still in reverse. The solution is to turn off the engine, wait a few minutes, and restart to reset the system. Additionally, occasional poor contact in the data cable connecting CarPlay can also cause muting—try switching to an original cable. If all else fails, enter the engineering mode by holding the MENU and CAR buttons simultaneously for 10 seconds to initialize the head unit. This operation is recommended to be performed under the guidance of the manual.

Last time when the audio wasn't working, I first checked the steering wheel shortcut keys. Pressing the mute button with a cross symbol near the right thumb twice can restore the sound. Then check if the mute icon is displayed on the center console screen, and tap to cancel if present. Volkswagen cars have another common issue: the phone automatically mutes after Bluetooth connection, causing no sound from the infotainment system. You need to disable the media mute synchronization function in the phone settings. Also, rotate the volume knob under the AC vents a few times to rule out poor contact. Remember to check if there's any damaged USB drive in the glove box, as that can affect the entire media system. Finally, the simplest brute-force method is to turn off the engine, lock the car, wait for the vehicle computer to completely shut down, and then restart - this approach can basically solve temporary malfunctions.
