Check engine light and it turned out to be the PCV, story follows...

[Sharkfin]

So I got a check engine light last Saturday and I had no idea what is was. Then when I got done with working on my car from 12pm-3:30am on Saturday (too long I know) then I realized what the symptoms were. When in park the car revs and after about 30 secs of revving sputters badly.

I drove around with it and in drive it works fine, but got to the Audi dealer today. After running the codes, there ended up being too much revving in idle (which I felt) and 3 out of 4 cylinders were misfiring. They said I should get it fixed relatively soon other wise once the PCV goes completely I will have oil all over my engine bay.

I got a slightly used one from them that I will install myself this weekend, but if someone wants to recommend the best site to get the PCV fix kit that would be great!

Cliff notes- if you car is revving while in park and/or sputtering, you might get a check engine light and there's a good chance its the PCV. Bottomline take a half hour and get it checked out.

out of warranty? That sucks. Perfect time to give the bsh one a try.

unfortunately yes, I just passed 50k over thanksgiving so I kinda got screwed. And audi quoted me $195 for the part from them which is the updated audi PCV.

[Sharkfin]

bumping in case anyone has the same issue!

[A4_Joe]

Do this test.

Start your vehicle & let it idle- try to opening the oil filler cap if it is hard to open tell them give yourself new freaking crankcase ventilation valve since there is recall for them.

[Sharkfin]

I'll try that tomorrow, thanks for the tip!

You can get one off of ECS for like 60$..

[Sanjman]

search for "eurojet pcv fix" and you should find that fix that will permanently resolve the problem and will never have to worry about it again.

They have two versions, the "F" and "E" versions for certain vins and range from 50-65. Those are just the updated Audi versions. I'm going to put the used one on and if it breaks I'll get one of those.

[A4_cabrio]

I have the exact problem and the car is at the dealership right now. they said they replaced a valve but that didn't fix the issue. Since it was the 24th they closed early and didn't have the time to do more diag

The only fail-safe PCV fix is the one from BSH. That is the one I am going for. I think it costs $99 but it will not fail again, the ECS, Eurojet and others have been reported to fail as well even thought they are more resilient than stock.

Did you try the test i told you to do??? What was the result from it??? I belive F is the newer version so i would go with F. If i'm correct E is a one before F

Let me know if you want any more info, I can give you it to take to let so they know. basically if there are misfires and you have revving or sputtering, you either need a new coilpack or PCV

I tried to get off the coil cap previously and yes it was hard to get off and I couldn't do it with my hand. I'll try with some tools sometime this weekend.

coil cap or oil cap??

if it is hard to remove the oil cap while the engine is at idle that mean you need new crankcase ventilation valve. What i would do is go to the dealer tell them you might possibly need CK recall, which is crankcase ventilation valve. The reason why i asked you to test that because that is how we test it at our dealership if they need new crankcase ventilation valve.

Sure they don't have the kit for the A4 on their website yet but if you contact them they will help you out.

Another Audiziner who has the system installed on his A4 but you don't need the full set up you only need the PCV fix.

I meant oil, and it actually came off pretty easily. I think its the PCV or the hose/seal. I tried both the C version my car came with and the E version which was eventually recalled, both fail to solve this problem. I'm going to order the E version from ECS for 65 and get the eurojet hose, I hope this solves my problem.

yeah I was searching last night and saw this but I am going to try the things I said above first, then we'll see if I've solved the issue.

[Sharkfin]

And has anyone experienced the catalytic converter getting so hot it turns bright frickin red? I got worried...

[Sharkfin]

Well I attempted to replace the PCV with the E version (my 05.5 came with the C version) and it was even worse. I am now on my way to my dealer to get a F version and will report back later today. Hopefully this puts me in the clear.

[A4_cabrio]

My car has been at the dealership for more than 1 week. I'm driving a pretty slick A3 in the mean time and that works for best since I have family in town and they dont keep my car clean when I drive them in it.

[Sharkfin]

Cool, I'd like to try out an a3.

So I got the newest PCV Audi makes, the F version and all is well, it works perfectly and only costs $55 bucks at the dealership. Popped it on, cleared the codes/CEL and it runs smooth. YAY

didn't i tell you to get the F?? You should have listen to me

[CX-7&A4]

I had this same issue along with a coilpack, my dealer went by VIN to tell me which I needed and it was F.

The thing is, it was leaking under the valve, so you couldn't really see it going out the window.

[A4_cabrio]

In my case it turned out to be the crankcase valve. The trick was to reset the throttle body after replacing. That got the engine to run smooth at idle again.

When the pcv goes bad does idle become unstable? My rpm's latly have been jumping from 900 to 1100 and sometimes even to 1300 for a second or two, and I recently got a CEL, I just haven't ran the codes yet to see what's going on.

Yes it will also throw CEL for it. I got a few, the one that came back very quickly was System Lean on Bank 1.

Yeah there is a late version VIN fix which is the F and the early VIN which is the E and with the E you have to get a new breather hose

Idle becomes more and more unstable as more pressure is lost. I'm guessing that is most likely your problem especially if it is just happening during idle. My car was revving for no reason and then sputtering, when it gets really bad the car shakes almost violently.
