2004 Volkswagen Passat Clicking noise only when turning.

I recently purchased a certified 2004 VW Passat Wagon with appx 77000 miles on it. 8 months later, after taking it for quite a few long drives, it's now at about 84000 miles. At about 82000 miles, I started noticing that when I turn left (sometimes right, but mainly just left), turning certain angles (from about 15-45 degrees), and above about 5-10mph, there is a clicking or popping coming from the front of the car. I know I have a certified warranty on the car, but first want to figure out a ballpark guess as to what the heck this is, before considering taking it in, as VW's are expensive to fix if not covered under warranty.
