How to reset the tire pressure light on Audi A4L?

In the latest models of the new Audi A4L, the tire pressure monitoring system has been removed across the entire lineup, retaining only the tire pressure warning function. In the event of a wheel issue, the tire pressure monitoring function can identify which specific wheel is experiencing the problem. However, with the tire pressure warning function, you only know that a tire has malfunctioned but cannot determine which one it is. The steps to reset the tire pressure light in older models are as follows: 1. First, press the "CAR" button, then locate the blank button to the right of "TEL". 2. Use the control knob to select the "Maintenance and Inspection" option. 3. Another interface will pop up; in this interface, click on "Tire Pressure Monitoring System", then select "Store Tire Pressure". 4. Two options will appear on the screen; select "Yes, Store" to complete the process.
Attention to all Audi A4L owners, as a mechanic with ten years of experience specializing in German cars, resetting the tire pressure light requires attention to detail. First, ensure all four tires are adjusted to the correct cold tire pressure, referring to the values on the door frame label. Then, start the engine but do not drive, navigate to the vehicle icon on the central control screen to enter the system settings, and find the tire pressure monitoring option (for newer models, the path is: Vehicle > Settings and Services > Tire Pressure Monitoring). Follow the prompts to store the tire pressure, and the system will recalibrate. After resetting, it's best to drive two kilometers to allow the sensors to refresh the data. Here's a common pitfall to note: resetting immediately after tire repair may fail; wait for the system self-check to complete for stability. For older models without a central control screen, use the steering wheel buttons to access the engineering menu—refer to the manual for specific steps to ensure accuracy.
Last year, my A4L had the tire pressure warning light come on, and I’d like to share my hands-on experience. First, park the car, turn it off, and let the tires cool for ten minutes. Use a mechanical tire pressure gauge to check the pressure in all four tires, then inflate them to the values listed inside the fuel filler cap. Next, start the car (don’t shift gears), swipe to the far-right page on the center touchscreen, tap 'Vehicle Settings,' enter the 'Maintenance' menu, find 'Tire Pressure Monitoring,' and select 'Store Current Pressure.' If the system prompts 'Busy,' wait about ten seconds and try again. The whole process takes about five minutes, but keep these key points in mind: the sensors may respond slower in rainy weather, and the light may take a couple hundred meters of driving to turn off after successful storage. If the light keeps coming back after resetting, visit a 4S shop to check the wheel speed sensors.
