Your gauge will now show a reading, note this down

Reattach the valve cap and repeat process for the three remaining tyres.

What should I do once I see a tyre pressure warning?

As soon as the tyre pressure warning light illuminates on your Audi dashboard, the first thing to do is to check tyre pressure of all your wheels.
