I've noticed a ticking noise that seems to be coming from the wheel area when I turn the car at low speeds. It may be happening at higher speeds, but I can't tell.

The sound does not appear to effect steering in that nothing detectable comes through the steering wheel when I hear the sound. The sound stops when the car straightens out

I initially thought it was a few small rocks or something that may have been trapped in the wheel well and were falling out at turn, or the exhaust but now I hear it everytime.

I searched and found nothing, other that a tick related to FSI engines. Anyone have a clue? Time Bomb under the hood? Audi clock noise?
