How do I reset the tire pressure monitoring system on an Audi A8?

I recently had new tires put on my Audi A8 and now the tire pressure monitoring system is giving me an error message. I've tried filling the tires to the recommended pressure and driving for a while, but the error message won't go away. How can I reset the system?

To reset the tire pressure monitoring system on an Audi A8, you first need to ensure that all tires are properly inflated to the recommended pressure. Then, drive the car at speeds above 30mph for at least 10 minutes while the system recalibrates.

In my experience, sometimes the error message won't go away even if all the tires are properly inflated. In this case, try turning the car off and then back on again. This should reset the system and get rid of the error message.
