If I push on it, or have my passenger push on it while we drive, it minimizes the sound. I remember reading a thread a while ago that the door rattle often has to do with some clips in the speaker grille that come loose or worn with time and rattle around. Google "E46 coupe door rattle" and you'll find probably close to a hundred threads on the topic, all using their own shaman voodoo magic to cure their rattle only to have another crop up.
