Passanger and Driver Side Door Noise

Last night was when it started. My girlfriend got into my '11 e350 4matic (Pano Roof) and when she shut the door it mad a weird noise as if something was loose. Now I cant really make out where its coming from. I don't know if its the windows off track a little, something with the sunroof, or even the pano roof. Please if anyone has had this problem before or is going through this with me please explain any of this to me... Ive had the car now only for two months and put 500 miles on it. I bought it CPO with 14,500 miles on it. Please any input from anyone right about now will help me.... Just please let the Mercedes family here help me out....
