How to reset the tire pressure light on Audi A3?

I have recently replaced the tires on my Audi A3 and now the tire pressure light won't turn off. How can I reset it without going to the dealership and spending money?

To reset the tire pressure light on your Audi A3, first ensure all tires are properly inflated. Then, turn on the car to the accessory position (do not start the engine) and hold the TPMS reset button (located near the steering wheel) until the light blinks three times. Release the button and the light should turn off.
