Bleeding e3/4/5's is kind of a trip. The e46 guys have some writeups on this down to a science, but basically, turn the key to on, heat to 90, three dots to red, and fill until its full. BUT, by full, I mean when its actually full per the mark, not until the reservoir is full. Thats why people keep blowing up ET's.
