replaced the n80 valve - no CEL, smoother idle, no vibrations when in D etc

[Trile]

25$ at the dealer.
Replaced it in about half an hour, would have been quicker if I didn't do it at night using the moonlight to see anything :) the only problem was getting the vacuum hoses of the valve.. First used a hair dryer but it didn't help so I poured some boiling water and then had to use my superpowers to get it off !

idle is smoother, the clicking noises of the valve are gone. downshifting and coming to a stop is no longer followed by juddering. When in Drive, it also doesn't vibrate as much. And of course, I don't have to pump the pedal to start the car after refueling.

Did you have a CEL?

[mo17k3y85]

what is this magical part you speak of?

[Trile]

yeap... the P0441 code. Emission control system:incorect flow, and few other related cels.
It sometimes poped up and stayed for a day or two and then went away. Last time it wouldnt go off for days, so I stoped being lazy and replaced the valve.

@mo17k - this is the part, it's positioned on the right from the pcv, you can't miss it :)

imho, everyone should replace this if they have more than ..hm.. 50k miles on the car. Or even less. It's like the pcv and the cam follower, it WILL go wrong.

[Leo14]

^ Whats going on in that picture there? Whats circled? I feel like its upside down for some reason idk. Good to hear everything is running better though!

[Trile]

the n80 valve (evap valve) is circled :) the picture was taken from above..I know i know, but i was in a hurry

here is another photo from another member on here,

[Leo14]

Ohhh I see, where did you get the valve from? Just hit 52k miles and am thinking about replacing anything that should be replaced, that way it doesn't randomly fail on me

[Trile]

dealer.
part number 06E 906 517 A - it's 17 to 20$

And it's not an 'updated' version like the pcv or DV so the old one will have the same number on it.

I also replaced anything members on here mentioned... dv, pcv, cam follower. Car felt much quicker after that, and I didn't even know my cam follower was slightly damaged and my pcv was on the way out.

[Leo14]

Ahh ok, wow thats not to bad at all. I just had my PCV replaced under warranty by the dealer not to long ago, going to get revision D DV soon hopefully, and I need to check my cam follower lol, little scared to though.. Thanks for the part # btw and the info. How long did the install take you?

[shiro1745]

I've tried to look the part up on www.genuinevwaudiparts.com it says it's $11.xx but it doesn't say there it's for our car(they have all this other models). It seems like I never find anything on this website. Can somebody give a hand here?

[tankdeer]

Just replaced mine about a month ago. $15 from the dealer, and only a few minutes to replace. Car runs much smoother now. Had the same code: P0441 - gone.

Shiro - it's for the 2.0T

[mo17k3y85]

so you have a code then replace? or replaced and it threw a code. Not sure what you guys mean by that.

So it short, code or no code change it if you at or over 50k.

[tankdeer]

CEL came on. Scanned it and found code P0441. Did some research and decided to replace the N80, which resolved the issue.

^^ your sir, have some serious knowledge!!

[Trile]

@tankdeer - same here.
love the forums ! :D

[stickyb7]

Did this a month or so ago + my PCV valve.... oh man, car feels like normal now. smooth and plenty of power

[ddanny86]

here is another photo from another member on here,

is this 2006 a4? i have a 2006 a4 2.0t i can not find where the n80 is...

[tankdeer]

Conversely, I have a 2006 and mine is exactly where it is in that pic. Facing the engine, it's back and to the right, under the PCV, slightly forward and more right than the HPFP

[shiro1745]

can somebody confirm that this is the right part?

Emission system Egr system Solenoid valve A3
05-08 $15.50 $11.16

This is what comes up when I put the part number above on genuineaudiparts.com.

Anyone with this error, also get a recurring gas cap warning? I'm stuck between replacing the gas cap (seal possibly bad) or replacing the n80 valve.

[B72.0T]

I just bought this at the dealership today $16. Will replace it possibly today, even though there's nothing wrong with mine.

I did not. If you're getting a gas cap error, I would check that first. Although the N80 is cheap so it couldn't hurt to do both.

I'll go with the valve 1st, as it's cheaper. If it's a no fix, at least I know the valve will be good to go for awhile. $17 at my dealer and being set aside.

Thanks!!!!!

[socaljoe]

I replaced mine just last week, problem was the car was a real pain to start every after re-fueling. I had to floor the gas pedal just to start it. After replacing the N80 purge valve, the car easily starts right up after re-fuel, and it's back to being smooth now. The part costed me $18 at the dealer

[digitalAUDI]

found it here for $14.89

[airbornerifleman]

I got the part from the dealer today for $18, I have no related codes but from some of the posts above and the price of the part, I couldnt resist.

OP: how did you take off the oem hose clemps, seem like they cannot be reused. BTW, thanks for the info.

If you're close enough to a dealer, I'd just go that route. So far it's been 16, 17, and 18 dollars from the dealer. Most online sites, you'll still have to pay shipping. And you might be able to get it on the spot, as my dealer had one in stock.

just buy a new set of clamps(I bought the screw adjustable ones), the crimp type clamps that were one were a pain to remove. I had to use a screw driver to pry it off the hose. Removing the clamps and busted valve took me about 45 minutes (and back ache). The new valve and new clamps were installed within 8 minutes.

my problem is that I am 40 miles away from the dealer and I'm pretty busy and never get there by the time they close. They won't ship anything to me. I'll try that link. Thanks

You should be fine using this clamp as a replacement if you fuck up the other ones:


I'll be installing mine tomorrow.

:)

Anyone else have experienced this juddering problem coming to a stop (tiptronic of course)? My car started doing that a while ago and this n80 valve might just be the answer if its true.

[tankdeer]

Not when coming to a stop, but mine would do it on start up and I had the issue after getting fuel a couple times as mentioned above too. For the price of the part, it's an easy thing to test

[B72.0T]

Mine does it. ^

[ataylor]

any reason to change this if you're NOT getting CEL? I see someone mentioned a reduce in the valve tick.. how is that possible via. upgrading this part?

[Gil2.0T]

im going to replace this just because im at 52k miles and its so cheap and so easy to do

[B72.0T]

Going to do mine now... gotta hit up AAP for some small clamps!

No offense meant to Tankdeer, but anyone with access to an autozone, 20 dollars, and google could have done this.

It even redirects to a 5 year old thread, here, that says the same thing.

Why am I getting called out on this? I didn't start the thread, nor am I confused on the fix. I fixed mine a couple months ago by basically the same procedure you recommend. Scanned it (myself), researched, replaced. I am just trying to help others with the same issue since it's such an easy fix

Yes, but nobody else did it here yet. So I think it's good info

Maybe check the price with your stealership first. Picked one up in Burlington, MA last night... got to the counter and it was $25. AARGH, I hate dealers.
