Does the Audi S4 have tire pressure monitoring?

[AshlynFitz]

Audi S4 is equipped with tire pressure monitoring. Tire pressure monitoring automatically monitors the tire pressure in real-time while driving and alerts the driver in case of tire leakage or low pressure to ensure driving safety. There are three commonly used tire pressure monitoring methods: Direct tire pressure monitoring: The direct tire pressure monitoring system uses pressure sensors installed in each tire to directly measure the tire pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and the tire pressure data for each tire is displayed. The system automatically alerts the driver 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 the other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. The indirect tire pressure alert system essentially relies on calculating the rolling radius of the tires to monitor pressure. Tire Pressure Monitoring System (TPMS): This system combines the advantages of both the above systems. It is equipped with direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared to a fully direct system, this hybrid system can reduce costs and overcome the limitation of the indirect system, which cannot detect low pressure in multiple tires simultaneously. However, it still cannot provide real-time data on the actual pressure in all four tires like a direct system.

The Audi S4 certainly comes with a tire pressure monitoring system, which is a common standard feature in German cars. It uses wheel speed sensors to monitor the rotation speed of all four tires. If there's any abnormal tire pressure, a yellow warning icon will pop up on the dashboard once the speed exceeds 25 km/h. Last time I was on the highway, my car alerted me about low pressure in the right rear tire, and sure enough, I found a nail in it when I pulled into the service area. Although it's not as advanced as high-end systems that display specific tire pressure values, it's more than sufficient for everyday safety. Tire condition significantly impacts handling, especially for a performance car like the S4 with its 3.0T engine—keeping an eye on tire status is crucial. Remember, if you get a tire pressure warning, avoid sudden steering inputs, gently apply the brakes, and pull over safely to check.

As a frequent driver of performance cars, I can confirm that the Audi S4 comes standard with a tire pressure monitoring system. It utilizes an indirect monitoring method, relying on ABS sensors to detect differences in wheel speed to identify abnormalities. Specifically, when a tire leaks and its diameter decreases, it will rotate more times than the other tires over the same distance. The system triggers an alarm upon detecting this discrepancy. Although it doesn't display specific pressure values, its sensitivity is quite reliable. Once, while cornering on a mountain road, the tire pressure warning light suddenly flashed. Upon stopping to check, I found the tire sidewall had been punctured by gravel. Such a safety feature is absolutely essential for a 340-horsepower car—without this early warning during aggressive driving, loss of control could easily occur. Additionally, here's a useful tip: remember to press and hold the SET button to reset the system after adjusting tire pressure for seasonal changes.

The Audi S4 comes standard with a tire pressure warning system across the entire lineup, which primarily relies on wheel speed sensors for monitoring. When a tire loses air pressure causing changes in rolling radius, the system detects abnormalities by analyzing rotational speed differences. The yellow tire pressure warning light with an exclamation mark on the dashboard will illuminate when attention is required. In practical use, I've encountered two false alarms - both occurring after tire pressure calibration when driving on highways, which turned out to be errors caused by rising tire temperatures. A drawback of this indirect monitoring method is that it requires driving some distance before triggering alerts, making it less intuitive than direct monitoring systems. However, it's perfectly adequate for most owners, especially for detecting slow leaks during long-distance driving.
