Vibration ticking sound in front door??
 

Hey guys, i just bought a 2007 Jetta Wolfsburg a month ago. Only like 800 miles on it now and the second day i had it . . .at like 50 miles, i started hearing a ticking/clicking, small metal vibration in the upper corner of the driver door. Thought maybe it is in the airbag in the bar between the front and back door, but when i put my ear to it, i dont hear it from in there. Sounds definately like a metal vibration in the very top of the door corner with the vibration of the car. It doesnt always do it which baffles me, until i hit a good bump and i can hear it click, then start the ticking vibration sound. Thought maybe it is with that metal cover on the door corner that runs top to bottom of the window area where the door meets the center bar between the front and rear door. Hard to explain this but it is RIGHT at my ear. . so it is extremely annoying when it starts to happen. When im on the highway, it is only noticeable when i hit a bump. When i am on back roads, if i open the window, it still makes the noise, and when i open the door when i am moving, it also still makes the noise, so its not a window thing or anything when the door is closed. I want to take it to the dealer but I want to have some idea what I am talking about if anyone has had the same problem.
Thanks
