Beneath the scuttle on the left side is a cavity for water to collect and drain. My 2006 simply has a hole in the metal about one inch in diameter and the water drains directly into the engine compartment. There is no duct/plumbing to direct the water to the bottom of the engine compartment. I've checked with a few BMW dealers and they were useless. If you have an E85 I would appreciate if you would check your car and let me know if something inserts in the hole and directs the water properly. For reference, the hole is directly behind the Positive jumper terminal. You should be able to easily feel the bottom of the drain hole (or some part attached to the drain hole) without removing anything e.g. the scuttle. Thanks for checking, I appreciate the help.
