Odd, I'm checking in with another Seattle cow bell. Seems to be more prevalent in this area of the country...

the noise comes and goes. i'm not certain that its a pebble in the rotor? alex long who's my SA at bmw seattle said he's never heard of any customers reporting this type of noise.
i plan to put my car up on my lift and check around the area. i'll report back what i find.
