Nope, never had any "flapping" noise at any speed. Even in the 100+MPH range, with the top up (I try to avoid doing that with the top up, but sometimes you just can't help it) I've never heard any noise coming from it.

I would check your top's alignment. There are a ton of alignment adjustments you can make to the top all over. Might be worth taking it in to BMW and have them take a look, would cost less than a new top!!
