I know. The wind was awful that day, and I am a one-man show doing the work with one hand, while holding the iPhone on the other hand. To say this is an amateur video job would be a compliment. I will be more careful next time
Great DIY video. Your engine is so clean. The power steering reservoir leak from the hose, it deos not look is leaking too much but when it does the only way to fix it is to put a new hose. Ask me how I know. And don’t use those hose clamps anymore. These clamps damage the hoses. instead use Ear Hose Stepless Clamps.
BMW F20N B38 triple petrol: P0444 P00171 lean mixture: cleaning fuel tank breather valve with MAF sensor (allowing it to 100% dry to avoid teflon dissolving because VANOS has teflon sealing washers) fixed the problem on 2x identical vehicles each with over 100k miles.
Thanks for the excellent video. That "quick release" connector is a very poor design. A metal clip (as in the electrical connector) would be much better.
started having a strong fuel smell last winter, which reduced dramatically when it started warming up a couple months ago. i was convinced my injectors were leaking, so i bought some new ones and replaced them. turns out I was wrong. took it to bmw of kobe and they told me that the purge valve was leaking. didnt know it was possible to have a bad purge valve and not get a code.
i have a e46 m3. p0444 code and o2 bank 1 code came up at the same time. causing a cel and some minor hesitation. just wondering if the p0444 code would be causing the o2 sensor code? does that make any sense? tank
Hi. General rule is that the probability of two things failing at the same exact moment is almost 0. This is true especially for vacuum related issues like this. Typically an upstream issue, will cause downstream sensors to also throw a code. It makes sense because if you are not getting the right amount of air to begin with, it will impact the rest of the systems after that. For example a DISA valve problem will throw lean codes on both banks, the same way this is happening to you, but in reality, there are not two things that are wrong.. In short, it is very likely that you only have one problem, not two. While I have not experienced these two codes at the same time myslef, I would definitely start fixing the problem upstream which would be the purge valve.
Every time I pump fuel in my car i have a hard time turning it on, I heard that it can be the purge valve or the fuel filter what do you think it could be?
Hello, i have the code P0441, recently changed the fuel tank breather, due to getting the code p0444, about a month later, im getting the p0441, any idea, what to check? or what could be wrong? please help! Bmw 325i 2002 e46
I replaced this and still have 276D but all other codes are gone, someone mentioned it could be a shadow code or something like that? Would it go away eventually?
Im actually performing this job on my 99 323i. Its a really easy diy, but I ran into an issue. The hose that runs to the bottom of the purge valve was missing from my car. This hose is somehow connected to the charcoal canister. I just cant seem to find where that hose disconnected from the valve and if I need a new hose, where do I connect the other end? Can anyone help? Thanks!
Hi Shaun. Take a look at this diagram for your car. Does this help with your answer or get you closer to an answer? www.realoem.com/bmw/enUS/showparts?id=AM33-USA-04-1999-E46-BMW-323i&diagId=13_0633

deasells fixed mine but you can get the p0444 code from having a bad fuel cap o-ring as well so id start there before paying $80+ for a purge control valve

Here are the schematics. I think the line you pulled is referred to as #3 here : www.realoem.com/bmw/enUS/showparts?id=AW33-USA---E46-BMW-325i&diagId=13_0798 It goes to the throttle body. With tiny hands, some people have been able to reattach it. Here are some pictures of it from different angles : imgur.com/a/lqzUVdU Also a forum link : www.bimmerfest.com/threads/fuel-tank-breather-valve-hose-came-loose-where-does-it-connect.1316541/
It would not. P0171 is almost always related to a vacuum leak. Unfortunately they are notoriously hard to trace. When I had that code , I started with my DISA o ring (very cheap, link to purchase below). If that does not work, I would look to replace the vacuum lines you can easily access from top of the engine.

It’s possible. This code does not give a check engine light. I just put the scan tool in my 01 E39 and gave me the same fault code with no CEL in my instrument cluster. But all of the sadden my mpg went from 20 to 19 mpg. I don’t know, maybe it does lower your mpg or maybe it does not just like Erol Eskinazi said.
This is the best purge valve replacement video on UA-cam. Thank you!
Scott thank you for the comment. learned it from others myself and happy that it is making it easier on someone else.
I know. The wind was awful that day, and I am a one-man show doing the work with one hand, while holding the iPhone on the other hand. To say this is an amateur video job would be a compliment. I will be more careful next time
Thank you! I have a E46 325Ci and had the P0444 code, changed the purge valve myself after watching your video. The check engine light is now gone.
Sweet. That is the reason I did the video. To help others like others helped me. Thanks for sharing
Thank you very much for the video, I replaced my purge valve in 20 minutes, you saved me hundreds of dollars. Awesome
Awesome. Thanks for sharing
Awesome video
Going to replace my purge valve tomorrow
Very practical video
God bless!
Cheers. Good luck with it
Very helpful and straightforward thanks!
thanks a lot for this good Video. I replaced this purge valve on my M54B22 today fast and without problems. Greetings from Germany
wunderbar!!!
Thanks Bro.. for a great informative Vid... We the People thanks you for your knowledge
Geerck901 thanks for the support. Go DIY community.
Excellent vid and explanation! Thanks 👍
Merci pour la vidéo , je vais pouvoir régler mon problème.
bonne chance mon ami.

Thank you for the comment. Like you, I ended up replacing the hose.
Thankyou very much for your help
I found the hose disconnected from the far end idk where it goes
Thanks you for sharing ! It helps !

R B thanks for this. Is tour tip then to clean the valve with MAF cleaner first instead of changing it?
Thank you very much, in Germany there is no video of of how to do it.
Bitte schön :-)

Great answer I've got the same thing too in my zhp. Gonna order and get it changed out thx for the vid definitely an easy DIY.
Every time I pump fuel in my car i have a hard time turning it on, I heard that it can be the purge valve or the fuel filter what do you think it could be?
I got the same issue. Did you find a solution?
Thanks for the video. What are everyone's thoughts on using sealants such as Drei Bond 1209 or 3M Silicone Paste to insure air-tight seal?
I personally never used them on vacuum lines. Occasionally I use a little bit of vaseline to make the new tight hoses connect easier, but that is all
Big NO NO NO. And may anyone who does such blasphemy spend and eternity removing such an evil thing over and over

Did this fix the "P0444 Evaporative Emission System Purge Control Valve Circuit Open"?

I change my purge valve on my 330i, but I am still getting this message evaporative emission system purge valve control circuit open. can someone help me please ?
Mine went away on its own but Ii believe it was after a few times of driving. Maybe twice or three times. Hopefully yours is the same.
Thanks bro very helpful. Hopefully it goes away.
Benz Jeanson Probably a little late now but have you tried a new filler cap, the rubber seal tends to deteriorate over time.
did it go away?
Can you clean the purge valve on a 3003 30 I BMW
Do you know where the other end of the vacuum line goes too ? I pulled it out
Here are the schematics. I think the line you pulled is referred to as #3 here :

@@ErolEskinazi thanks a lot. I will check it and get you a feedback.
anyone knows the part number of the hose that goes in the valve ?
Yes. Two breather lines go into it. It is either 13907557924 or 13907558190. Take a look at the schematics at this link. goo.gl/q9ALRV

Did u find out wehre it gose i just made this mistake from an hour ago and i didn't find out what to do HELP!
fteddyfingaz same here did you find out?
JAD Al Koko did you find out?
Did any of you find out?
where did you purchase part
I use www.ecstuning.com
could this cause bad gas mileage?
No it is purely an emissions related part.
It’s possible. This code does not give a check engine light. I just put the scan tool in my 01 E39 and gave me the same fault code with no CEL in my instrument cluster. But all of the sadden my mpg went from 20 to 19 mpg. I don’t know, maybe it does lower your mpg or maybe it does not just like Erol Eskinazi said.
What were the symtoms?
John Lira just be P0444 error for me. No other symptoms that I could hear or feel or see.
