an acquaintance of mine recently tore up a chain of an X5 (2009 model) and had to buy a whole engine.

Since no pictures exist on the internet (that can be found) on where exactly the drain comes out at, hopefully this picture will help describe how you can help yourself figure this out: I found this video of a guy removing the AC box from an e46 330i. In the above circled area is the drain location on the AC box itself. This would correlate to the center ...
