Is the PCV different with the 3.0? Different location? Not looking forward to dealing with myself considering all the comments.

My car had a CEL and loud squealing sound when warm.
Dealer says it's PCV valve and about $2K to replace due to the huge labor involved as the parts are buried in the engine.
Checked with Fidelity Warranty (I have the platinum plan) and they have approved the repair.

Wow, Fidelity approved something.

I have heard mixed reviews on them. I am told a lot is dependent on the relationship between the service advisor and claims adjuster from Fidelity.

In an older Porsche I used to own they authorized a $22,000 engine :-)

my PCV valve started squealing last night.... I'm dropping it off today at lunchtime. I remember reading this thread recently, so luckily i knew what it was right away.

im in california, so i'll post back what happens.. my car is out of factory warranty by four months - but i have an extended warranty and possibly the CARB enhanced emissions warranty.



from my warranty (what is not covered):

(d) Breakdown of any part which the United States Environmental Protection Agency (EPA) has determined to be emission related, which is included
on a current list published by the EPA of such parts, and which is within the EPA time and mileage emissions warranty period.

so it looks like if the emissions warranty doesn't cover it - my extended warranty will pick it up. (Fortegra)

I looked up the part before for the CA emissions warranty. It is not covered according to Audi, though I disagree with the underlying conclusion. The fine point legal debate is whether the part was in general use as of a baseline reference date. To me the problem with their position is while PCV valves have been around forever, this is anything but the simple plastic ball in an orifice $5 part. If I understand part correctly, it has combined the oil separation function and in ways not even on vague drawing boards a couple dozen years ago. I haven't had to service it personally, though also had the fine oil separation set up (trouble free) on D3 W12 as a very early implementation but that also had super easy access to it if something broke. Given Audi's position, nothing can be done about it unless someone wants to take it to court. Hopefully your other warranty covers. If enough claims and enough noise though, maybe somehow a service action/recall ensues. Unfortunately it seems like a recurring theme as the posts roll out on going on 5 year old 4.0T's.

I took this EPA pamphlet circa 1992 with me..

If I am reading it correctly, it says my PCV valve should be covered... as I am under 50K miles (only 45K) and under 5 yrs old... but I'm sure it will be a fight.

I'll escalate it to wherever necessary... for it to be covered (if the legal information in the pamphlet is still truly applicable).

I could also have it fail a smog test right now (CEL is on) to fall under the "Performance Warranty" aspect of what is described.

Anybody know if this is outdated? It is still on the EPA website and #1 search result for: PCV valve emissions warranty

They called and said it is the oil separator and equally as pricey
to replace. Extended warranty approved... won't get car back for a few days.

Looking for seem insight (new to the forum and posting). I have a 2007 Q7 3.6L in which the the pcv recently died. I confirmed by checking the hole on the box which had a high vacuum on it in addition to not being able to get the oil cap off due to high vacuum. Long story short i bought a new membrane and all the parts to do the job, however as i got into it I opt'd not to deal with the fuel rails so i took to a repair shop. Well that has turned out to be a nightmare been going back and forth several gas leaks and a couple missing bolts. But now i see i have oil forming around the spark plug coils and an high positive pressure in the crank case, i actual get oil coming out of the dip stick tube when i remove the dip stick. So i am headed back again, i did do a test from some documents i read on line where i removed the breather hose from the pcv vent side, i plugged it and started the car. Everything ran great, no pressure on dipstick tube and only slight pressure coming from fill cap. Similar to how my TT is set up. This would indicate that potentially the membrane was not installed correctly, thoughts?

Sorry, this is the forum for the current generation D4 A8/S8. This model Audi does not use the motor referenced either, including in Europe AFAIK. You should post on the Gen 1 Q7 forum.
