How do I reset the Audi A3's tire pressure monitoring system?

I'm having trouble resetting the tire pressure monitoring system on my Audi A3. Can you walk me through the steps?

To reset the tire pressure monitoring system on your Audi A3, first make sure all tires are properly inflated. Then, locate the reset button under the steering wheel and hold it until the TPMS light blinks three times. Release the button and the light should turn off. If the light remains on, you may have a malfunctioning sensor that needs to be replaced. As for the recommended tire pressure, it can be found in your owner's manual or on a sticker in the driver's side door jamb.

I've found that disconnecting the negative battery cable for a few minutes can also reset the TPMS on an Audi A3. Just be sure to have your radio code handy as you'll need to re-enter it after reconnecting the battery.

One simple solution could be to take your car to a mechanic or dealership and have them reset the TPMS for you. They have the necessary tools and knowledge to quickly and accurately reset the system.
