PCV Valve Malfunction-VCDS

[andrios]

Hey guys

I did a random auto-scan on my 2015 SQ5.

Got this... I didnt clear it yet. I have my 35k service hopefully this week or next.

Anyone have an idea?

Thanks!

I got this error code too a few months ago. Was ready to call the dealership, but cleared the code and it never came back. Curious to see if anyone else got this error too.

I will let the dealership know when I take the car in Monday.

[rusq5]

Bumping an old thread. I got this too.

Anyone have it come back?

[rgvsq5]

I got same code on my 2015 SQ5... have cleared it twice now. Not noticing any loss of oil and it's not throwing a CEL.

I got this fault 20136 - PCV Valve Malfunction too and ignored it until i read this thread
https://www.audiworld.com/forums/q5-...epair-2962694/
I was about to flash my ECU, so i took my car (about 30K) to the dealer and asked about this fault. The dealer
fixed it with new PCV and valve under warranty

[andrios]

Wow I told my dealer about the issue and they did nothing about it while I was in warranty. Now I’m out of warranty and it’s still popping up.

[Smittylube]

I've been getting this one as well. Put it out of my mind till I recalled some 2.0's when the CCV valve fails it pulls the main seal with it.

Might be a good idea to replace the CCV.

Wow!!!! Just had this replaced... didn't know I could have brought it in..

[dubgli]

Is there a way to check our vin to see if this pcv valve warranty applies to us? Short of calling them up.

- dubgli

[djn876]

Probably not without calling them. Likely only applies to early models.

Had the same intermittent code during the colder months over 2 winters. Occasionally I’d get a noise at idle that sounded like crazy vacuum leak or a stuck lifter on an old v8. The noise seemed to happen more when I was due for an oil change. Brought it in and they replaced the PCV under warranty.

Were you over the normal warranty 50k/4 years?

Over the factory warranty but covered by the CPO warranty at ~73k

[dubgli]

Just following up : I called the number in that link and gave them my vin.

My car is not covered by this extended warranty, but they suggested I call the dealership to see if they can do anything for me.

[dubgli]

Took the car to the dealership for the soft code for pcv valve malfunction. They didn't even want to see me unless its a hard code. (when will i learn!)

They said I just passed my warranty and that the car does not qualify for the extended warranty on the pcv valve. It would be 2-3K dollars for the repair.. WTF!!

the service rep did suggest I reach out to Audi USA so I just did that. They said they will get back to me.

Anyone have to reach out to Audi USA after their warranty was up? What are the chances they will throw me a bone?

So I read that you can test for a bad pcv valve by removing the oil cap when the car is running. If there is a lot of suction, the pcv valve is going or bad.

This clip seems like a lot of suction. Would you all agree?

similar issue paid to have it done wish i knew this.

[dubgli]

Chances are, the sq5 is not covered. Mine was not covered by the extended warranty for the pcv valve.

It was a miss-understanding on my part. I thought my PCV valve was replaced, but it wasn't. The thermostat, water pump, and breather hose was replaced.

That's why I'm back in this boat with the PCV valve. I don't know why the shop skipped over the pcv valve and I just didn't know enough to request that they do the pcv valve while in there. my mistake!

[dubgli]

So both the dealer and the indy shop told me that the 3.0T motor is okay to continue driving short term as long as I keep an eye on the oil level. The indy shop proceeded to tell me that it doesn't have the issue the 2.0T motors have where it will blow out the rear main seal.

Oddly enough, i know all about that on the 2.0T as I also drive a Tiguan which had that exact thing happen. Anyone here with that experience? Just topping the oil off and keeping an eye on it should be okay short term until it gets fixed? Or should I just not drive it period.

[Gmoney227]

I had the same code on my 2015 Q5 3.0t. Got the PCV valve replaced (not under warranty). A week later the code came back. Don't notice any driveability issues before or after.. Might just ignore and hope for the best.

[djn876]

If it's using a lot of oil, it's also coating your valves in them, so definitely get it addressed sooner rather than later. It could also start putting coolant in your oil depending on the failure so watch for level going up too.

[Gmoney227]

Mine is going through oil changes every 4500-5000 miles which I figured is average for a time car. Haven't noticed any loss of coolant.

lmao literally EXACT situation happened to me its kinda crazy! had to got back to have the pcv valve after doing all the same previous work!! i wonder if its connected??

My coolant level has been steady, not dropping.

In the video I posted above where I took the oil cap off, I also checked the dipstick and it looked completely dry. I freaked out, shut the car off, went to buy some oil in my other car, came back an hour later. I checked the dipstick again with the car off this time and it was full.

Is that normal that when the car has been running and is still running, the dipstick will show low?

- dubgli

[djn876]

I don't know as I've never tried it, but would imagine yes since it is being pumped through the system. Manuals seem to all say check oil level hot after the car has been off for a few minutes, allows for draining back to the pan.

[dubgli]

Fixed!

So it was just the tube that connects to the pcv valve. All good for now.

Hoping Audi if America still comes through and extends my warranty or something on the pcv valve.


I also have the entire parts kit to replace the pcv valve if anyone is interested. Paid $130+. I'll create an ad in the classifieds.

Just want to add for future readers trying to diagnose. When my vehicle with known bad PCV was making dieseling/stuck lifter noise, I could not easily remove the oil cap while the engine was running, the vacuum on it was crazy. When I did get it off, and instant vacuum relief noise followed by elimination of the dieseling noise occurred at idle. When the engine was running without the noise to begin with, the cap was easy to remove with no change in sounds.

[Nicahm]

Hey. Do you have the part number that Fox the problem, i have same issue and still after changing the PCV

[Smittylube]

More info for you DIY folks.

06E103207AP, Crankcase Breather Pipe is the solenoid part that goes to the intake bellows/CCVv.

When the CCVv fails it can suck oil in as well make a noise at idle. I had one customers car in with a failed valve and swore the noise was belt or bearing noise in front. The noise went away with the oil cap removed.

Based on time, mileage and my 20136 code I replaced my CCVv as well as water pump, Tstat and heater pipe (needs to be removed to get CCVv out.). I wanted to not worry about the Tstat and wp on a long drive. My code returned, CCVv diaphragm was not torn at this time.

This breather pipe with solenoid is like a one way valve and in testing a new one and the one in the car I used a vacuum pump at the hose on the bellows. New one held vacuum, stock one did not. When I removed the solenoid if I tapped it or moved it the valve would reseat and hold vacuum. So far after replacing the breather pipe no more codes. I have not gone further testing with Vagcom to see what happens open or closed when energized, But I suspect it still functioned, just didn't seat properly each time.

My point is replace this part when you do everything else. There is a diaphragm in the CCVv as in the others like the 2.0. They tear over time from oil getting on them. so expect to replace it 60/90+k and be done. Call it maintenance on these .

[ezridah]

Agree ^^ i have both a 14' and 15' Q5 and both needed the PCV replaced between 90-95K. The warranty bulletin did not cover either unfortunately -- not sure what magic has to happen for that to apply...

[MSq5]

I'm at 75.000 miles. Mods in signature below. I've been getting the PCV malfunction code (no CEL) intermittently for several months. Now it comes back right away, and there is strong suction when removing the oil filler cap with the engine idling. Also slight engine oil loss (maybe one quart per 5,000 miles I never had before AND a little coolant loss. There is also a slight engine oil smell in the cabin but no leaks, no exhaust abnormality.

All adds up to PCV valve failure. I've ordered the kit with all gaskets, the oil separator/pcv and the pipe. I also ordered the water pump and thermostat and will do it all while I'm at it. Likely will clean the intake valves and will inspect for intercooler leaks while at it.

It just seems like we all have to do this at around this mileage, give or take.

[Vehicle 1]

Are you getting the "Confirmed" or "Not Confirmed" designation to the Fault?
I get a "Not Confirmed" fault for now... will see what happens.

Yes, mine is "confirmed" now.

[ezridah]

Started as an intermittent code, flipped to confirmed, noticed an odd moment or two when accelerating and took it in for diagnostic/repair. Never threw a CEL in either car so don’t wait for that - suspect CEL will show up a day late and a lot of dollars short…
