Ok,

2004 V8, with 128k on odo.

When she runs well, she runs like a beast.....BUT.....

After searching that the PCV disc is a common part that goes out on our Treg's and Audi's, I decided to buy one and replace it. The old one was loaded with oil.

I had the goose honking going on pretty bad out of nowhere. It pretty much creaped up on me last week (about 7 days ago). I replaced it 2 nights ago, and it is now doing it again, after a brand new one installed.

I have been very patient with this Treg (1st german vehicle owned/worked on), and have replaced just about everything that are the common issues with these.


Does anyone have any ideas, before I tear this thing apart, limb by limb?? Should I tear the rubber hoses that connect it, off & clean??

Thanks! :anger:

yeah i've gone through 4 PCV's in 3 years. All varying qualities. honking is coming again but really quit right now. I know what to listen for but others would not.

1 - all hoses clamped tight ?

2- OEM or after market PCV. Some are just plain rubbish. I tend not to buy the cheapest but also not a VW one .... somewhere around the middle mark seems reasonable.

3 - could be indead faulty dont discard this also. If you are satisfied that its connected properly i would call out to the sales agent and see what they say about a swap.

It was about middle of the road cost wise!

Looked at values from $50 to $125...Settled on Middle of the road on Amazon ($70+), based on fairly positive reviews.

I will re-look at the hose clamp tightness, because you are right that I may have not tightened them enough!

I will give it a shot (I guess), and see if that corrects the problem (fingers crossed)!

Off the wall question about these German PCV Canisters: Does the honking kill anything (short-term) while driving it??

Just wondering due to how it worked great fro 2 days, and still drives fine, after it started honking again.

cant answer the off the wall question really my understanding is the engine is try to breath and the diaphragm inside the PCV helps achieve this without the bad noise although you have jogged my memory on something.

The last time i replaced a PCV it still did honk a bit for a few days and then went away until now which has been a year.

I wonder if the the PCV needs some kind of lubrication in the form or engine oil sweat or something for it to work affectively. Or it comes from the factory with a thin layer of oil to ensure the rubber part inside does what it is suppose to do .... that is move up and down and somehow mask the noise.

You did say you only just replaced it .... id give it a week or so and maybe 100-200kms

Thanks Odessa!

I'll clamp them down tighter, and give it a few days of engine use. Fingers crossed that it works, since it makes some sort of sense.

Just ordered the OEM, ouch! Hopefully this fixes the annoying honking sound, after replacing it with this knock-off. Apparently the one on there must not have been OEM either, due to the fact that the hose clamps were not original.

Are there any other tips, like cleaning the hoses attached to it?? Or just attach OEM like normal, and let it ride??

Did the new PCV fix it?

On other (lesser) cars a honking noise is made by the idle control valve.
You can usually get away with cleaning it.

Had the same issue with our '07 V8. Thought it was in the belts at first. Ordered a PCV, $115 later I found out I had the newer style PCV. So I have an early V8 PCV sitting in the trunk of the car.

Easy fix though, just expensive
