Which button controls the air recirculation in Audi A3?
3 Answers
Audi A3's air recirculation button is located on the center console, to the right of the temperature regulator, with an icon depicting a car containing a rotating arrow. The introduction to Audi A3's air conditioning buttons is as follows: 1. A/C switch: This is the so-called air conditioning switch, which controls whether the compressor operates. Inside the compressor, there is an electromagnetically controlled clutch. When its coil is energized, the electromagnetic clutch engages, and the compressor operates. Otherwise, the compressor's pulley just idles, and the compressor does not work. When the air conditioning switch is pressed, you will hear a 'click' sound, which is the sound of the compressor's electromagnetic clutch engaging. 2. Air recirculation mode: This controls whether the blower draws air from inside or outside the vehicle. Generally, the recirculation mode is used during cooling, meaning the blower draws air from inside the vehicle. 3. Air temperature adjustment: The air is cooled by passing through the evaporator of the cooling system and heated by passing through the heater core. The proportion of air flowing through the heater core is controlled to adjust the temperature and humidity inside the vehicle. Air outlet mode adjustment: This adjusts which parts of the vehicle receive airflow, such as the upper part, the panel, the footwell, or a combination of these areas.
I'm an experienced Audi owner who has driven an A3 for several years. The recirculation button is located on the air conditioning control panel, usually in the center of the dashboard or near the screen area. There's a small icon that looks like a car with an arrow pointing inside or outside the vehicle—pressing it toggles the function. It's typically next to the temperature knob or among the cluster of AC function buttons. Newer models might integrate it into the touchscreen menu, but the physical button version is more intuitive. I use it frequently: in city traffic, I activate recirculation to avoid exhaust fumes, while on long highway drives, I switch to fresh air mode for better ventilation. Don’t worry about wearing it out—it’s quite durable. Button placement may vary slightly by model year (older versions on the left, newer ones on the right), but the icon remains consistent. If you can’t locate it, check the manual—it’s clearly illustrated there. Ultimately, remember this simple button significantly enhances driving comfort, especially in areas with poor air quality.
As a long-distance driver, I particularly value the air recirculation function in my Audi A3. The button placement is simpler than expected—located in the climate control panel on the right side of the steering wheel, typically integrated into the main button array with a dual-arrow circulation icon. One-touch switching is effortless; I always switch to recirculation mode on rainy or foggy days to prevent moisture ingress and use fresh air mode on sunny days to save AC power. Audi’s design is consistently user-friendly—this button is unpretentious yet practical. A quick tip: avoid prolonged recirculation to prevent cabin odors. The button responds instantly without lag. If it occasionally sticks, it might be due to poor contact or a software glitch—try restarting the system. Overall, the intuitive placement makes it easy to locate, even for beginners, and it’s a game-changer for maintaining air quality on long drives, saving me a lot of hassle.
