noise turning left

[cdm5go]

I was wondering if anyone else has encountered this problem before, or if anyone has any insight as to what the cause may be. I have a 2005 X3 3.0i manual transmission with the sport package. It seems that after I release the brakes and make a left turn, there is a squealing noise similar to break squeal. It only happens after I release the brakes, and only when turning left. It is fairly loud and eventually goes away until I step on the brakes again. It doesn't happen while my foot is on the brakes, only immediately afterwards when I turn left. I have been to my local dealer twice and I keep ketting the same answer; "We were unable to duplicate the problem, everything seems just fine." The car is still under warrranty and I want to have it fixed before the warranty is up. Thanks in advance for everyone's help.
