Mein Auto: '11 335xi Sedan
Mine exhibits a mild whistle from the side mirror from roughly 40-60mph. Below that, nothing; above that, either the resonance is obliterated by increased flow or it's just lost in the background. I notice very little wind noise at freeway speeds--tire noise tends to dominate until triple-digit speeds. Above about 120mph (going from memory from ED; sadly I can't do that here...) the wind noise becomes a formidable roar--not enough to preclude conversation in normal tones, but enough to make the base of your brain say, "OK, we're going plenty fast now...."

Whistling by your left ear at high speed does not sound normal. You might want to have the window glass and seals checked/adjusted, to ensure the glass is fully seated in the seal when closed.
