Where does this go? I have searched xoutpost.com, realoem.com and Google. It is just hanging out at the front of driver's cylinder head. It is a rigid line with a squared bend at end. See picture

I believe that's a vent/breather from the transfer case. http://www.xoutpost.com/bmw-sav-foru...um-line-2.html

Thanks just bizarre that it just dumps there.

It doesn't just "dump". There is not enough volume in the tfr case to produce a liquid output at that point - it is merely to allow pressure normalisation as temps change within the tfr case.

As Anthony said it is for. It is raised high in the engine bay to prevent water from entering while driving through deeper water.

What I meant by dump is it just stops there with no cover

Correct its a vent tube! Weird location for it but nothings going to come out of it.
