That's the coolant temp sensor. O-ring on that temp sensor fails, leading to leak. O-ring can be purchased at the BMW dealer for couple of dollars. You can also buy a new temp sensor. New sensor comes with new o-ring.

Very easy to replace the o-ring on the temp sensor. Pull the metal clip on the temp sensor and pull the sensor straight up; remove the electrical connector on the sensor; remove the o-ring and replace it with new one.

Here are the pictures - the temp sensor goes in to that hole in the hose.
