Where is the tire pressure display for the 2021 Audi A6L?

2021 Audi A6L tire pressure is displayed on the control panel. There are three common methods for tire pressure monitoring: Direct Tire Pressure Monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It uses a wireless transmitter to send pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. The system automatically alerts when the tire pressure is too low or there is a leak. Indirect Tire Pressure Monitoring: When the pressure in a tire decreases, the vehicle's weight causes the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between tires, the system monitors tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Introduction to Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above. Direct sensors are installed in two diagonally opposite tires, along with a 4-wheel indirect system. Compared to using only a direct system, this hybrid system can reduce costs and overcome the limitation of the indirect system, which cannot detect when multiple tires simultaneously have low pressure. However, it still cannot provide real-time data on the actual pressure in all four tires as effectively as a direct system.
For my 2021 Audi A6L, the tire pressure display is located on the digital instrument panel behind the steering wheel. You can simply press the VIEW button on the right side of the steering wheel to bring it up—there's a dedicated tire pressure interface. If you're still unsure, you can also find it through the MMI system on the center console: press the CAR button to enter vehicle settings, and then look under the maintenance and inspection menu for real-time tire pressure data. I always check it before long trips since unstable tire pressure not only wastes fuel but also increases the risk of blowouts. Audi's active monitoring system is far more accurate than old-school mechanical gauges. Tire pressure varies quite a bit between summer and winter, so I recommend checking the values monthly. The manufacturer-recommended cold tire pressure is usually listed on the sticker on the door's B-pillar.
Last year, I bought my dad a 2021 Audi A6L. When teaching him how to use the tire pressure monitoring system, I found the operation quite intuitive. After starting the car but before shifting gears, look at the central display on the instrument panel. Use the arrow button on the left side of the steering wheel to toggle left and right until you find the 'Service' section, where the tire pressure information is located. I make it a habit to check the tire pressure after every car wash because the attendants often inflate the tires to inconsistent pressures. If the display shows only dashes, it might mean the system hasn't read the data yet; just drive a few hundred meters, and it should update. Audi's tire pressure display can monitor the pressure differences among all four wheels in real-time. Last time, it alerted me to a slow leak in the right rear tire, saving me from a potential breakdown on the road.
