How can I reset the tire pressure warning light in my Audi A3?

I recently replaced my tires on my Audi A3 and now the tire pressure warning light won't turn off, despite the tires being properly inflated. How can I reset the warning light?

To reset the tire pressure warning light in your Audi A3, start by ensuring all the tires are properly inflated to the recommended pressure. Then, turn on the ignition without fully starting the engine. Hold down the TPMS reset button located under the steering wheel for about 10 seconds until the light blinks and then turns off.
