I have the exact same thing, my boyfriend thinks I'm crazy and doesn't hear it. Says wait to see if it gets worse, and it's worse in cold weather right??? I thought mine was the Master Cylinder break fluid reservoir cause it kinda jiggles a bit in there so he zip tied it. Today it was warmer and I did not hear it too badly, but I still do hear it...sooo slight... I too took mine in for the noise and they said it was the steering I Shaft. But it was not the fix... I have a '07 Convertible. Let me know what you find out... Sux, it's just annoying.
