What's this little tube?

[Troy_K]

OK, here is really hoping that I don't make myself look like an idiot.

I have searched all around and cannot figure out what this is, and hope somebody doesn't show me a bunch of posts what I have missed.

OK, I have a 2002 X5 4.4

Anyhow, Under the plastic cover on top of the engine, on the (left side of the car), right to the front of the valve cover, is a little black tube. There is nothing connected to it. I was trying to see if it was supposed to have a vacuum line or something connected.


I have added pics, if that helps at all.

Thanks all,
