Is it a drone or more like a clatter? That's how mine got started - clatter at cruising speed and low idle, then it started making noise at cold start-up. Mine ended up being, like a lot of X3 owners, the hose to the muffler was slightly torn. the dealer fixed mine under warranty. If you are out of warranty check the hose for cracks
