Basically, the headline is already the whole question: Yesterday I came because the windows, especially the windows were quite fogged on the idea to open the windows. And when the windows at the back were opened c.a. 1/4 to 1/2 [they are not going up] [and I drive more than 60 km/h, nothing is before] this strange, incredibly loud and dull noise came. It comes quite close to the “Fap” noise of this Bell UH, just a little duller.http://www.youtube.com/watch?v=HKEVpypGUBI&feature=yo utu.be The strange thing: When I open the windows in the front I don’t hear anything from it until hardly anything[vill I imagine only one] Also if the window is open in the back[no matter if left or right] move you also the seats something and you mean to notice an unbalanced through the whole car. But if the windows are at the top you can’t notice absolutely anything, and the car drives softly 200. The matures can’t be either, today is still there. hen, the mature ones aren’t kind of loose-I can hit it with the foot and it doesn’t move a mm-even if it’s lifted I guess that the wind is making the noise, but I’m a bit worried. Has someone ever had something like this, someone knows what it might be? Ahja-hab is trying to record the noise, but you can imagine how great the recording sounds in advance of THX. ever since
