Where is the external circulation on the Audi A4L?

The Audi A4L does not have an external circulation button, and it automatically defaults to external circulation when no buttons are operated. Here are the relevant details: 1. Exterior: For the Audi A4L's exterior, the 35TFSI Progressive and 40TFSI Progressive models come standard with the S-line sports package from the previous model, with slight differences in the rear bumper and exhaust pipe details. 2. Upgrades: The new model features two additional USB ports across all variants and has upgraded air conditioning. Additionally, the prices of some models have seen minor fluctuations, but the value for money remains excellent given the added features. The new A4L 35TFSI Progressive continues to be powered by the EA211 1.4T engine, delivering 110kW (150PS), while the 40TFSI/45TFSI models maintain their power outputs at 139kW (190PS) and 185kW (252PS), respectively. All models are paired with a 7-speed DSG transmission, with the 45TFSI variant also featuring the exclusive quattro all-wheel-drive system.

My old A4L has been running for five years. The external circulation button is most conveniently located on the center console's AC panel. Look for the car icon with an arrow inside - when the light is on, it indicates internal circulation; when off, it's external circulation. Never use external circulation in traffic jams, or you'll get all the exhaust fumes inside. On highways though, you should turn on external circulation for ventilation, otherwise prolonged driving gets stuffy and dizzy. Audi's AC system is quite sophisticated - when automatic AC is on, just press this button to toggle modes, very intuitive. If you can't find the button, simply tap the 'Air Circulation' icon on the center display to switch modes. Page 37 of the manual even has diagrams, though you'll memorize it after a few uses.

I just picked up my new A4L, and there's indeed a crucial air circulation control button on the AC panel. It's the small car icon with a curved arrow on the right side - when the light is on, it means the external circulation is off (internal circulation mode), and when the light is off, the external circulation is active. I used to mix them up at first, but later discovered that turning it off works wonders when the windshield fogs up, as fresh outside air quickly clears the fog. Remember to activate internal circulation (button illuminated) when driving through areas with poor air quality, otherwise you'll be sucking in all the dust and pollen. The design is quite user-friendly - you can operate it blindly while driving. The salesperson advised during delivery that prolonged use of internal circulation may cause oxygen deprivation, suggesting to switch to external circulation for ventilation at least once per hour.

Research on Audi's vehicle system reveals that the external circulation control is hidden in two places: the physical button is located on the right side of the air conditioning panel, marked with an icon of a car exterior and an arrow; while on the touchscreen, it's accessed by entering the air conditioning menu and selecting the 'Circulation' mode to switch. When external circulation is activated, fresh air is drawn in through the front grille, but in traffic jams, you might smell the exhaust fumes from the vehicle ahead. Turning on external circulation on rainy days clears fog faster than using the air conditioning cooling mode, though it's advisable to switch to internal circulation before entering tunnels. When automatic air conditioning is enabled, the system defaults to intermittently switching circulation modes, but manually pressing the button temporarily overrides this setting. It's recommended to manually switch to internal circulation in areas with poor air quality to protect the respiratory system.
