PCV Regulator Valve Performance*P052E00

[Ashs4b8]

So I recently replaced my PCV and everything went well. But after a long drive yesterday I'm getting a rough idle. Plugged in the obdeleven and received this error code "PCV Regulator Valve Performance*P052E00". Does anyone know what else would of set this off? I bought the PCV from Audi and I'm not losing any oil or coolant.

[aonavy]

Maybe a fluke? Can you clear it?

Yea I can clear it but it keeps coming back.

I had the same exact code on a fairly new PCV. Took it back to the garage that replaced it for me. They actually tested the PCV and it turned out to still be functional. Reinstalled it and took it for a test drive. Same code came back. It turned out to be a the solenoid coming off the PCV that was stuck open and air flowing all the time. It's called the crankcase breather pipe, part number 06E103207AP. I only got it back 3 days ago and so far no code.

I'll check it out. I didn't replace this part. Thank you for this info!

This is a common issue. The solenoid is causing this fault. You most likely needed the breather as well though. They all fail.

Please confirm the part(s) you are referring to - 06E103207AP is a breather hose, it has a inline check valve but no solenoid (by definition a solenoid is an electromechanical part) so it is not clear what part you replaced. Did the check valve fail? Not trying to be picky just want to make sure in case I need the same item. Like most PCV items VAG charges a fortune for a little bit of plastic so I want to get the right part. Thanks!

That was the part listed on my invoice from the garage. And that's how it was explained to me. I guess it's that check valve that failed. Sorry for the confusion. Maybe they manually activated a solenoid to test the check valve?

Okay, I am in this situation right now with Audi and trying to get this code P052E00 addressed. I had my PCV replaced about 17,000 miles ago but this code has popped up since with the associated symptoms (oil consumption, strong vacuum when taking oil cap off etc.)

That being said the part number that is being listed on this thread and the one that Audi is telling me is needed in addition to a new PCV is 06E103207AP. However, when I search this part on Audi Parts, it tells me that "This Part does not fit your car";

https://parts.audidominion.com/p/Aud...e103207ap.html

Any insight into this? When I search FCP and ECS they also both state that this part will not fit my car...

https://www.ecstuning.com/b-genuine-...e/06e103207ap/

Bottom line, is this a valid part for a 2017 SQ5?

[djn876]

There were two PCV versions of I remember correctly, technically both would fit, but the later one may require a tune revision in order for it to function correctly and not give the error message. Could also simply have been a bad part too on the initial replacement.

The other parts I can't speak to, but might be worth looking at since it could be the issue with why this one went bad so fast.

I have heard about needing to tune or update the ECU for the new PCV. in fact there’s an updated part number for the PCV that has come out since I had it replaced back in July of 2020. So I’ll make sure to bring that up.

What I am asking about the parts I listed above is wether or not that part actually fits on the SQ5. When I pull it up on the Audi parts website it says it doesn’t. My dealer is insisting it does fit and that it needs to be replaced

Don't worry what the Audi parts website says -- it's usually right but not 100%. What you need to be doing is doing the search with your VIN. Don't waste your time worrying about stuff like will this or that fit my car and which version do I need, just buy the part using your VIN instead cause that's 100%. I see so many people here making this basic mistake.

One example of this is www.audiusaparts.com and you will notice when you checkout you have to provide your VIN.

Same thing is happening to me in my 2013 A6. Just replaced my pcv, still getting a soft code. I'm going to replace the breather tube and see what happens.

I had bad oil consumption & was blowing blue clouds of smoke from it. The pcv swap fixed the blue clouds, but I'm still having oil consumption.

Thinking about grabbing the 65$ tube from fcp... If it breaks early at least it is warrantied for life.

Since I had the crankcase breather pipe, 06E103207AP, replaced back in December, everything seems to be running smoothly. My Q5 was alerting me for a quart of oil every 2,000 miles before. Now, no more soft code and oil consumption is greatly reduced.

[Silent Sassin]

Seeking a little guidance from those in the know...So I've been having the usual signs of a bad PCV valve (strong suction on the back of the valve, oil cap difficult to open with engine running etc.) so I went ahead and replaced the cap with the Dorman unit that everyone's been using. The old cap had a big tear in the diaphragm, so I got great results from the new unit. However, I'm still getting a bit of suction at the back of the new valve, but the oil cap is much easier to open now (I've been told that some suction is normal).
Drivability is much improved, but I'm still getting a slightly rough idle and the car feels a bit sluggish on move off. I'm wondering if I needed to replace the entire PCV valve and not just the top. Is there any test that I can do to tell? Also, I hear much talk about the crankcase breather pipe with the check valve being stuck open, are these symptoms of that? Can I test that also?
Any help is greatly appreciated.

Which engine do you have? When you describe "strong suction on the back of the valve" and replacing "just the top" it makes me think you have a 2.0T?

My bad, yes it's the 2.0T (2011)
I'm just trying to do some diagnosis of my own, unfortunately there aren't that many "reputable" shops here that are versed in Euro's (IMO)

Just an update on my issues...

My PCV Code has gone away since replacing the Breather tube that connects the PCV to the Supercharger.

Still burning oil on deceleration... suspect exhaust valve stem seal failure.

Question, the breather hose that you mention being the issue, is replacing that part still require taking the supercharger off?

85% of the cost to repair the Breather Tube/PCV is in labor costs. The parts are relatively negligible in cost once you factor in what your already spending on just the labor. I had the work done at Audi under warranty and they would have hit me for 5.5 hours of labor to do the PCV, which essentially the same amount of time it would be to do just the Breather tube. Maybe knock .5 off the total labor time.

I think parts all in was around $400.00 and that's with buying all new gaskets and the injector "Grommet" kits that cost an arm and a leg etc..

Agreed, if you dig into the motor far enough to replace the breather tube, then you might as well go the extra step to replace the PCV as well, especially since they are known to fail frequently. It's not fun to dig into the motor a second time for an item that could have been replaced while you were in there the first time. Speaking of... perhaps look into replacing the thermostat and water pump if you're gonna be doing the PCV. They're also pretty much in the same spot and you'll save a ton on labor if you do it now vs waiting for them to fail later.

Though if budget is really tight, yes, you could technically probably fix your issue with just the breather tube and leave everything else alone.

[hananmori12]

Ok I see, I thought the tube it’s easier but I got it.
I will order water pump and thermostat just in case.

Someone have the list of part for pcv?
I have those parts:
06E103547AH
06E103213
079129717D
079129717B
034 Supercharger Bleeder Screw Kit

My new-to-me 2016 SQ5 had this fault code show up in a scan. I found this TSB for what needs to be replaced: https://static.nhtsa.gov/odi/tsbs/20...77763-0001.pdf

I haven't fixed it yet, I'm researching options of if I want to do this myself. Also thinking of doing everything at once. PCV, Water pump, Thermostat.

If you are going to go in there, definitely replace the whole PCV and the hose. Waste of time and effort to take all that crap off and not just replace the whole deal. It could be that hose, or it could be the entire PCV, that code could be either.

About to order full PCV kit from FCP....people have said to replace the breather hose with check valve. Did they chance something with the 06E103207AP hose in 19'? It's saying that doesn't fit the wifes vehicle.

Any help would be appreciated

I'm not sure but I changed that hose on a 2016 it was causing intermittent check engine light without any other oil consumption Etc I bet you I just needed this check valve but the shop just decided to replace only the PCV valve and I still got the light could actually hear the check valve rattling once it was removed so thankfully they paid for my labor the second time around

Well, the problem is, the part with the check valve shows it doesn't fit the 2019 Q7 3.0T. And, I can't find a similar part for the 2019 and up models. Car giving intermittent CEL and pulling codes with OBD11 gives me the PCV performance error, as well as small intake leak. Trying to get everything I need so my local indy shop can replace all this crap. Pisses me off that my stage 2 tuned 2018 RS3 has been flawless, but this Q7 has been a nightmare for the wife. Btw.... I've had 8 Audi's, and never had issues like this thing.

Is there a quick and effective way to check the breather hose on 3.0T before taking everything apart?

I’m about to do the PCV change due to this DTC code and I called a dealer to verify for my 2017 Q7 3.0T. The part previously mentioned 06E103207AP doesn’t fit because the correct part is 06E103207AR. This part is on FCP and ECS for a little cheaper than a dealer. It will also fit Noogman’s 2019 according to FCP.

This is the issue. I didn't replace mine even though the original code is why I replaced my PCV body as that was one of the suggestions and seems to go bad anyway. But the breather hose looked fine. I just put on a new clamp and put everything back together. I cleared all codes and was good I thought. Now I have the same one, so I'll be pulling the SC again and putting on a new pipe. The elbow could also be the issue, but for the money, mind as well replace it all.

[mkornegay2]

Is the same part. The AR is Genuine and the AP, AH and AC are OE which is also genuine but they scrub the Audi logos/names for licensing and you get it for 1/3 cheaper. The manufacturer makes these parts for Audi and they just rebrand and mark them up.

[mkornegay2]

I wish. Doubtful.
