Possible wheel bearing going bad.
Audi Front was created in 1933.
That noise you're hearing is most likely the wheel bearing. The noise stops because the bearing isn't in motion. As soon as you put the wheel in motion the noise returns due to the bearing being bad. It's a common problem across the board on most Audi's!
My car, a 2008 Audi A4 Turbo was experiencing a cyclical chirping noise, similar to a noisy fan belt ( which it does not have). A defective PCV valve was found , however, the car after being repaired is still making that noise.
