Engine question about my BMW X5 4.4l

Hi guys/girls,
can anyone please tell me if this solid plastic pipe needs to be connected somewhere. It's that curved pipe almost touching the radiator fan.
I'm also trying to solve an SES issue, P0444 Emission circuit open. I've googled and already replaced my gas cap but I still have that SES
Thanks in advance.

That's breather tube for transmission, it's suppose to be open like that. Not the source of your code.

Thanks guys.
About the purge valve, what I did was I disconnected all the very snug hoses and removed the valve then applied 12v and it worked fine. All the hoses look perfect to me. I connected the hoses then ran the engine. I measured the voltage from the plug and it showed 10.5v. Maybe I should have tested the valve with that lower voltage but I didnt. Then I plugged the electrical back in while the engine is running hoping to feel the actuation of the valve but theres just too many moving parts at that point to feel one click. I went to the dashboard and the saw the SES disappeared. WTF. I dont know what worked but it cant be an issue with the plug because i've disconnected/connected that many times before. I'm thinking applying 12v to the valve loosened it up and started working again.
Well I just hope it lasts long enough for the state inspection. Can you guys tell me where to buy one of these purge valves? I looked at pelicanparts and it doesnt look like they have it.
Thanks again

Thank you , thank you, thank you...one less thing to worry about. Just got my 06 X5 4.4 about a week ago..and just getting a chance to take a better look at the engine (the n62 engine is all new to me)..and saw this curved tube not connected to anything and wondered if it should be connected.

Started doing forum and internet searches but was getting no where until I came upon this thread that also had a pic of the tube.

Im glad I found a thread that had an actual resolution to the initial inquiry..instead of the many dead or unresolved threads I keep running into on the X5 forums.
