The starter relay sits in a relay panel above the glove compartment. You have to remove the glove box and drop it down. The relay panel looks like this little white storage tray, and it has 4 relays in it - a tall black one in the back, and three short white ones in front. The starter relay is the short white one furthest to the left. FYI the relay panel also has 2 fuses on the side of it - one 50 amp and one 40 amp. Bentley lists a designation number of K6324, but I don't know if this will help with BMW as far as a part number goes. It's all that's listed, though. Good luck.
