BMW clear is self healing. My F30 has it and my last 2010 E90 had it. Leave car in sun for several hours. This will help re-flow the clear to effectively make the spot disappear, though I would NOT recommend using a heatgun. They get HOT and can damage the paint finish. Stick with a blow dryer if you cannot find enough intense sun for a few hours. On the other hand, I've heard some in the paint industry say its the suns UV rays that activate the self heal. I guess it depends on which manufacturer's clear BMW used on your car.
