How do I reset the tire pressure monitor on my Audi?

I've noticed that my tire pressure monitor light is on in my Audi. How can I reset it so that the light turns off?

First, check the tire pressure in all four tires to make sure they are all at the correct pressure. If they are not, add or remove air as needed. Then, locate the reset button in your car, which is typically located near the steering wheel. Press and hold the button until the tire pressure monitor light blinks three times, and then release. This should reset the monitor and turn off the light. If the light continues to stay on, there may be an issue with one of your tires and you should have it checked by a mechanic.
