Check your owner's manual. Detailed instructions with pictures in there. It's very easy to do. You basically have to remove the trim piece to the inside edge of the fog light fixture so you can slide the fog light housing out. Then just unplug the old light bulb, plug in a new light bulb and reverse the removal process. 2002 530i takes an H8 bulb.
It's easy, you'll have to remove the small black air dam portion next to the fog light structure. They have plasic ension pins, just pull down and it will pop out. You'll be able to get at the light easily once they are removed.
