How to Turn Off the Radio in an Audi A4?

Audi A4's radio can be turned off by: 1. Pressing the CD button to switch to CD mode; 2. Long-pressing the volume adjustment button to turn off the audio system. Taking the 2021 Audi A4 as an example, it belongs to the mid-size car category with body dimensions of: length 4762mm, width 1847mm, height 1436mm, wheelbase of 2825mm, and a curb weight of 1665kg. The 2021 Audi A4 features a five-link independent suspension at the front and rear, equipped with a 2.0T turbocharged engine, delivering a maximum horsepower of 204ps, maximum power of 150kw, maximum torque of 320nm, paired with a 7-speed dual-clutch transmission.

Just helped my sister adjust her Audi A4L last week. The most straightforward way to turn off the radio is by pressing the silver knob on the center console—the volume control button has a power symbol right in the center; press it firmly until you hear a 'click,' and it shuts everything off. If you just want to mute, there's a speaker icon with a slash on the left functional area of the steering wheel—a light press instantly mutes. By the way, post-2018 models with touchscreens are even more convenient: swipe up from the bottom of the screen to bring up the control bar, then tap the red power button. Friendly reminder: try to use the steering wheel buttons while driving—looking down to press the center console is quite risky. Last time, I accidentally triggered the voice assistant while reversing and nearly hit a trash bin.

When driving my old A4, I was always startled by the sudden blaring of the radio. Later, I figured out three solutions: First, simply turn the volume wheel next to the light knob on the driver's side clockwise to the minimum for mute; second, operate through the MMI system by pressing the CAR button to enter the media interface, select the radio channel, and tap the close option at the bottom right; third, press and hold the '*' key on the center console for three seconds to force mute. New car owners, take note: if you're listening to music via CarPlay and it suddenly switches to the radio, it's likely due to poor phone connection—just unplug and replug the data cable to fix it, no need to fiddle with the head unit.
