I've recently let my e63 w211 sit for about 2 weeks and upon driving it everything was fine untill I reach speeds about 70+mph and I start to hear a wind/dragging noise idk what it could be when I let the window down I'm fairly certian it goes away pretty odd issue but it would be appreciated if yall help (passengers say it sounds like it's coming from driver side vent other person with similar issue said his comes from the dash)

 

I recommend checking the moldings on the driver side door. Ensure the "little nipples" that inserts in the holes. Check for tears, bends, and fittment. GL
