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.
A quick search on my regular obd site didn't have much info, a quick google search led me straight to a bmw forum with somebody with your exact problem, just because it's reading your valve open doesn't mean it's so, you may have disturbed a vacum line when working on your car, at any rate I'd say google will have to help you with this one, what kind of vehicle are you working with?

I'm sure the black plastic pipe was not made to just dangle there. I imagine it went to the EVAP canister control valve somewhere near the intake manifold. Try to find a Bentley manual. It doesn't have to match your model Bimmer exactly. They are a wealth of information.
That code is related to the EVAP valve, which is part of the fuel system and located in the engine bay. If I had to guess, your dangling hose is part of that system. Try posting your question and pic on bimmerforums.com in the X5 section, they should be able to help you.
I think if you take a real good look you will find where that dangling hose became unplugged from. Those things don't wander to far from where they belong.
Find the place to park that hose and I'll bet your emission fault goes away.

I'm with you guys. But someone from the BMW forums said its venting for the front diff and its fine hanging like that. I'm like huh? this hard pipe is actually laid out on the engine bay side wall, with the ABS brake lines. I'm kinda hoping he's wrong but I think I found a pic
weird.
I know where the purge valve is but this pipe does not connect directly to that valve.
I'll check these hoses tomorrow. I hope I find something
My first question is "has anyone tampered with the car" If not be sure the purge solenoid connections are connected and that the purge canister is too. You do know what Im talking about dont you.If not you are in over your head already and will need a mechanic. This stuff is standard on all cars made after 1996.

Noone has tampered with the car. I do all the car work for all 6 cars which includes full suspension work, replacing injectors, turbo/water pump replacement etc. I've built 3 race engines for SM
Just looking for visual confirmation, chief

P0444 code fixed. What I did was I disconnected all the very snug hoses and removed the purge 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 light 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.
P0444 code fixed. ... I'm thinking applying 12v to the valve loosened it up and started working again.
The P0444 code usually refers to an electrical problem, not a mechanical problem with the EVAP purge valve itself. A constant battery voltage is applied to one terminal of the purge solenoid. The wire from the other terminal goes back to the ECU where it is grounded through a switching transistor. When the switch is open, the ECU expects to see battery voltage at the input to the switching transistor (because no current is flowing); when the switch is closed, the ECU expects to see near zero voltage at the input to the switching transistor (because current is flowing and the battery voltage is dropped across the solenoid coil). If what the ECU sees and what it expects to see differ, a DTC is set. One of the DTCs is P0444. It think it means the solenoid circuit is open.
I'd be curious to learn how this is resolved. Keep us informed.
