I just purchased a 2006 Range Rover Supercharged and am having a weird issue. I am experiencing a loud "howl" that seems to be effected by the wind. If I'm going directly into the wind, it's much louder, if I'm going with the wind, it's not near as loud. I can even tell if it's gusty because the sound changes with the gusts. To make it even more weird, it's much worse on the drivers side than the PAX side. It's a very loud but low noise. Any ideas????
