You can reset the tire pressure light in your Audi A6 by following these steps: 1) Make sure your tires are properly inflated. 2) Turn on your car's ignition. 3) Press the TPMS button located under the dashboard. 4) Hold the button down until the indicator light blinks three times. 5) Release the button and the light should turn off. If it does not, try repeating the steps or consult your owner's manual.
