URGENT: 4.0T Turbo Death Whistle!!!

[elweed004]

I am on a trip from Denver to my parents place in Arizona. I have 190 miles left and as I stopped for gas I heard the whistle coming from my 2013 Audi S6. From those who have experienced this issue, how long from the time you heard the whistle until complete failure. Do you think I can make the 190 miles or should I accept failure and have my father travel the 3 hours to come get me with his car hauler? Thanks in advance for the help.

Another note is that i am getting the whistle when I'm off the accelerator coasting or sitting at idle.

I’m almost positive you’re fine to finish the drive. The whistle is very likely a failed PCV valve which is covered under an extended warranty

Thanks J71, I was just reaearching and realized it was more likely the PCV Valve. Anyone else who has had the PCV issue have an idea how long I can drive her with this issue going on? I'd hate to get stranded in the middle of the desert, especially if I'm in an area with no signal.

I’m even more certain it’s your PCV valve with this comment. You can make it back.

I drove around with mine whistling for like a week before taking it in to get it fixed. I don’t think it’ll cause issues. If I recall correctly, an Audi tech told me it’s fine to drive around. It was just more embarrassing than anything else. I don’t think you have to worry about getting stranded in the desert based on the failed PCV valve.

By the way, you should consider upgrading your turbos while you get it fixed under the extended warranty

Thanks again J71. I verified it is PCV by taking the Oil cap off and running at idle to see if whistle still exists as I saw on other posts. No whistle with cap off, so PCV it is. I will continue on my journey and get fixed upon arrival. Appreciate the assist!

Imo, if I were you I'd pay a little extra for them to check the shaft play on the turbos and replace the check valve and oils screen to the current version. Its good insurance to help keep those turbos alive longer.

Thanks again J71, I made it to my destination just fine, though the CEL did come on when I started the car after stopping for a restroom during the drive.

Appreciate the insight MolonLabe300. I was planning to do the Check Valve, PCV and Oil Screen as well as checking on the wellness of the Turbos before realizing I needed to make this trip, but just figured I would wait until I got back.

J71 mentioned the PCV being covered under an extended warranty, which unfortunately I do not have. Now that I am out here in Arizona (about 70 miles out of Tucson, small town, no Audi Dealer or Indy Euro/Audi Shops) and I do not have access to my own garage, I am trying to figure out my next course of action. In my fluster yesterday, I didn't put two and two together to recall that the PCV is the Oil Separator and that is part of the work that I was planning to do and the extent of what that work was.

Now I need to order all the requisite parts and find a shop, likely in Tucson, that I can pay the labor hours to do the work. From what I have read, any good mechanic should be able to do the job in 8 hours, so I am hoping that I can find someone to do the work properly and not try to eat my wallet. Anyone have any suggestions for a shop in the Tucson area that is reputable and won't gouge me to get this done. Also, in these times, I would prefer to support a small business if possible .

Pcv is covered under factory extended warranty. I believe 120k miles. Essentially a recall

Thanks Lilrckt. I started looking into it and I am trying to make a little more sense of it. So I know the list of parts that i would buy to do the job if I were to do it myself, but if I am having an Audi Dealer or Authorized shop do the work for the PCV under warranty, what parts from that list would I need to buy to complete the Oil Separator and Oil Check Valve? I want to make sure that I get the parts that I will be paying out of pocket for at a better price than a dealer would charge. This is the list I was planning to get to do the work on my own and what I know what will and won't be covered, and what I am unsure on. Do I have the full list of items that are needed, and for each of them listed I am pretty sure that everything is covered because it would be necessary for the PCV Valve work itself, aside from the Oil Check Valve, Oil Strainer and Crankcase Vent Valve Seal. Can anyone confirm for me? I will order the parts that would not be covered in the morning and get the work scheduled.

Oil/Air Separator - 079-103-542-E (covered under extended warranty)
Oil Check Valve - 079-103-175-C (not covered)
Oil Strainer - 079-115-175-G (not covered)
Crankcase Vent Valve Seal - 079-103-161-Q (not covered)
Driver Side Intercooler Gasket - 079-129-717-J (covered?)
Passenger Side Intercooler Gasket - 079-129-717-K (covered?)
Throttle Body Seal - 079-145-818 (covered?)
Bypass Valve Seal x 2 - 079-145-417-B (covered?)
Clamp x 2 - N-904-898-01 (covered?)
Clamp - N-904-095-01 (covered?)
G13 Coolant Gallon x 2 - GA137741GDSP (covered?)

Thanks again for all the info everyone. This has been super helpful.

You might want to talk with the dealership first. They might be more willing to work with you on adding labor on top of warranty work if you buy the parts through them. This is coming from someone who hates paying dealership prices.

I will chat with Audi Tucson in the morning and see what they have to say. Honestly, either way it will be better than what I was expecting to pay for the work. I just hope they can get me in and get it done by Friday so that I can get back on the road to Denver on Saturday morning.

[hanyoung]

Hopefully I can return some of the good Audi karma that Audizine helpers have thrown my way! As for the $ that inevitably has also been spent.. well...

elweed004 - sorry to hear about your situation. I'm in Tucson as well with a 2013 Audi S6 - so far, no PCV failure. I think the first ? is, are you tuned or TD1? If so, I would not go to the dealer as will be all out of cost.

A great local shop is Stuttgart Autohaus - they really know their Audis and have done a great job for me. Their rates are very reasonable as well. Phone is 5208848800

I used to have horrible experiences with Audi Tucson - but they have really turned things around. So much, that I purchased AudiCare from them on my S6. Given I have an extended warranty, it's in their best interest to do good work but I wouldn't hesitate to recommend them now that they have a new service manager. Unfortunately parts can be an issue as they may not have them in stock, but they have plenty of loaners available while you are waiting. I've worked with Robert Goodrich and Tony Madeiro in the past and received great service.

Best of luck!!!

Thanks for the info. My S6 is not tuned, so I should be good to go there. Due to time limitations, I am kind of stuck with Audi Tucson rather than getting it up to Phoenix, so hopefully they do a good job. I am getting ready to take her up to them right now. I have the TSB, Extended Warranty Info, Video file of the sound that comes from the TSB and the Parts List for the work related to the PCV as well as the additional part necessary for doing the Oil Check Valve and Oil Screen work while I they are in there. Hopefully that will limit any "assessment" they need to do to determine it is in fact the PCV issue that is tied to the extended warranty and we can get to talking about the other parts and labor involved with the 5 minutes of extra work to replace them.

Thanks again to everyone for all the help, this board has been super helpful in getting me through this. All in all, it is kind of nice because I should come out having all the work done by someone else that I was planning to do, for around the same price I would have paid for the parts alone if I were to have done it myself. Can't ask for much better being so far from home and my garage and tools.

[hanyoung]

Nice good luck and stay safe!

[Audisom]

For anyone reading this in the future, I put a strip of an old t-shirt tied to an adjacent vacuum line or something near the oil cap and put a piece completely under the oil cap. (The vacuum held the cap in place and every week or 2 I had to shift the shirt around to stifle the whistle.) This stopped the embarrassing and obnoxious whistling while I waited for the parts to come in. After doing more research while I waited for time and good weather I discovered AUDI might cover the fix (they did) but all in all I drove approximately 1500 miles like this with no further or other associated problems from the delayed repair so you got some time to sort it out. Good luck

[elweed004]

Update: I took the car into Audi Tucson on Monday afternoon and spoke to one of the Service Advisers there. I told him that I was coming down here from Denver and that when I pulled into one of the stations, as soon as I let off the accelerator I was getting a high pitched whistle coming from the engine area. I told him that I did some research that I turned off the car and pulled the oil cap and started it back up with no whistle, but as soon as I stopped the car and put the oil cap back on and started it up, the whistle was back. He knew before me saying that it was the PCV and there was an extended warranty for that part. I had trailered the car up there just to save myself the embarrassment and had the ability to.

The Service Adviser told me to get the car off the trailer and pull into their drop off bay and just leave it running. He said he would like to waive the $175.00 diagnostics fee, so if we let it sit there until it got warm and started whistling, he would not have to diagnose the issue any further than that, and that fee would be unnecessary. I told him that I would like to have the Oil Screen and Oil Check Valve replaced while they were in there since they were in the same area. He said he would figure out pricing for parts and labor for that and get back to me that evening. Oh, and on top of that, he reminded me that I had a 65k service that I had gotten when I bought the car that was about to expire and asked if I would like to have that done while it was there.

I headed back home and received the estimate back from Audi in the morning. Things were off as they did not have the cost of the PCV work zeroed out and they did not have the other parts or labor on there, etc. but that was really because their Service Advisers are working split shifts due to the coronavirusstuff, so the one I spoke to had to hand things off to another adviser as he was not in the office and was working from home. He was in contact though and worked with me through text to get part numbers because they were having trouble finding the Oil Screen I had mentioned (he hadn't needed any of the stuff I brought with me regarding the TSB or the Extended Warranty, but I should have just given him the parts list I had compiled). After I provided him the part number he found it. He got the parts ordered since they would need to get them out of Los Angeles and they could possibly take until Thursday to get in and I had told him I needed to be on the road Saturday morning back to Denver.

I woke up this morning to a completely revamped estimate to approve. It was right at this point. The PCV Service was zeroed out as well as the diagnostics fee, so they only cost that I was looking at was the $241.86 for the Oil Strainer, Oil Check Valve and Crankcase Vent Valve Gasket, plus tax coming to a total of $269.56. This is about half of what I was going to pay for parts to do the work myself. I should have it back Friday evening or Saturday morning so I can get back on the road. Thanks again everyone for the input and assistance. I would say that my experience with Audi Tucson has been a good one, but I would say it is also very helpful to know what is needed before you walk through the door.

Glad to hear it worked out for you man.

That is a PHENOMENAL estimate/dealership. I just had the same thing happen to me with a 'replace while in there' list. They claimed the oil strainer was 4 hours of labor on top of the PCV valve and I absolutely had to have an oil change, even though I just changed it ~1000 miles prior. Long story short, my tab was ~$1500 for the 'extended warranty' work....

I'm sorry to hear that vastano. I really think that me going in there and having information to tell the guy about how many extra bolts need to be removed to get to the strainer and check valve helped me. By the time I explained what was happening and gave information around what needed to be done and referenced the TSB and Extendrd Warranty, the young fella seemed a little intimidated and didn't want to try any add-on stuff. I guess I baffled him with what I'd learned over the couple days before going in there and made him believe I knew far more than I really do. I attribute that to the members of this forum and related info I found through other threads.

If they are following the TSB properly $241 extra sounds about right...vastano's $1500 was crazy high...that stinks.
According to the Audi TSB:
Remove + reinstall oil strainer and check valve = .7 hours ~ $126 even if they pushed it to the outrageous 1.5x of listed time it shouldn't be more than $200 in labor.
check valve 079103175C = $76 msrp
strainer 079115175G = $16 msrp
crankcase vent valve gasket 079103161Q = $35 msrp

Even at 4 hours labor @ $150/hr + a ridiculous high $150 oil change shouldn't have pushed it to $1500...it sounds like they charged for the whole PCV replacement.

Hey GK1, what TSB is that information from? I just spoke with Audi Tucson about my car and the Service Adviser told me that he is working from home today but spoke with the Service Manager to check progress and that they have the car apart, but are not able to complete the work that I have asked them to do because there are a couple seals that they were not aware they needed to complete the extra parts I wanted replaced (oil strainer and oil check valve) that they cannot get until Monday. On top of that he is saying that he was informed that it is 4 hours worth of work to do the Oil Strainer and Oil Check Valve. I told him that was BS and that once the Oil Separator was removed, it was literally a matter of removing the bolts that hold down the Crankcase Vent Valve, lifting it off, lifting the Oil Strainer off, and the Oil Check Valve from underneath it, removing the gasket and then putting the new Check Valve in, then Oil Strainer, gasket and then placing the Crankcase vent valve back on top and bolting it down and then they are back to PCV Valve replacement work. If that took more than 30-45 minutes I would be surprised. He is going to have the Service Manager call me.

Can anyone confirm that outside of the parts required by the TSB to do the PCV Valve replacement, the only parts that should be required to do the Oil Check Valve and Oil Strainer would be those two parts, plus the Crankcase Vent Valve Gasket?

If they are saying that there are parts that they need, I want to be able to say that is on them as I provided the part numbers for the Oil Strainer, Oil Check Valve and Crankcase Vent Valve Gasket. I would also like to be able to prove to them from their own documentation (TSB referenced in previous post) that they should only need .7 hours to complete the work.

I'm in 100% agreement with you that it should not take much more time to do the strainer and check valve if the car is already apart to do the pcv. However, they may have a standard "book time" they are required to charge for the extra work. Whereas the TSB is just listing the actual warranty time it takes to just take the screen and valve out and put the new ones back in...anything else...even turning 1 screw might be extra.
The TSB is 2044640/5 date November 28, 2018 but I am not sure if they may be up to a later revision now.
https://static.nhtsa.gov/odi/tsbs/20...53123-9999.pdf
Page 5 "Remove + reinstall oil strain and check valve" = 70 TU (100 TU = 1 hour)
The only seals I can think of are the lower oil line seals. Maybe a coolant line seal too.

Oh and BTW not to add to your headache, but if the car is stuck with them you may want to ask them to replace the piston oil cooling jet solenoid it is bolted into the crankcase vent valve and also uses a small screen to filter oil and there has been at least one instance of the solenoid failing due to the same screen issue as the turbo. The part is relatively inexpensive ($60 06K115243AB) compared to the labor as you see and IMO is worth doing at the same time.

Wishing you luck as this sounds more like a typical dealer as they all quote the "book" regardless of what the ACTUAL work might be but you do have a pre-work quote so hopefully that will protect you at least partially.

Personally I find book time to be bizarre. How is it legal to bill someone on what it “should be”, and not on actual time that was spent on the car? I wish we had it that way in medicine though.

Not sure about Hofa, but I saw the email regarding this and it reminded me that I had been meaning to send an update.

Audi Tucson was able to get the parts they needed on Saturday morning and get things wrapped up by Saturday afternoon. I went and picked the car up that evening before they closed, test drove it around Tucson for a bit and then threw some gas in her and drove the hour or so back to my parents place. No issues whatsoever. Total after getting the extra parts was $331 and change. All in all, it worked out since I got everything done that I got done for the amount of money that it cost and without having to do it on my own. Also, I was able to have them check on the health of the turbos while they were in there and get my 65k service done as well.

I made the trip back to Denver on Sunday and drove straight through with no difficulties. She ran like a champ. Though I did have a little frustration that Audi Tucson did not look at the parts that would be needed to do the extra parts I had asked them to do while they were in there which caused the extra day for them to get things done, they did good work and they were straight with me and there was only an increase on the price of the parts with the mix up. For the most part, it was a good experience with Audi Tucson.

Thanks for the help AZ Fam.

Thanks GK1. In speaking with the Service Manager and the Shop Foreman, they were apologetic and said that based on what I was having them do, they definitely should have known that what parts were needed. While I think they made up some money from labor on the cost of those parts since I do not think it was an extra $60 in parts for what was essentially o-rings, I saw it as a wash. $331 and change is still just fine by me based on the level of work they did and the amount of work it saved me in the long run.

Glad to be through it and have some peace of mind regarding my turbos and the rest of the car for that matter.

My car just started making the whistle of death noise as well. I took your advice and put an old t-shirt under the oil cap. It didn't work unfortunately 😭. Sound still loud. Maybe I did it wrong? I noticed a significant lose in power, especially accelerating. Did your exhaust shoot out white smoke? Did you have extended warranty for Audi to cover it? I scared of driving it but I need transportation for work 😕.

There is an extended warranty out there right now for 10yr/120k miles if you have blown turbos. You should not be driving a car that way, as you may cause more catastrophic damage.

Take it to the dealer to get it looked at and fixed. Have them give you a loaner

I don't believe the turbos are blown. The whistle is coming from a fail PCV. Is there any way to check if you're under extended warranty with Audi? I have a 3rd party warranty.

Loss of power is not indicative of a failed PCV… unless that was a placebo effect you were having.

They have the extended warranty for PCV too. Call you Audi dealer and ask them to verify

I scanned the car with OBD11. Fault Code p2279 came up. Every post Ive read everyone said it was their PCV that failed. Not once did I read about turbos blowing from that loud whistle sound. Even the person who made this post. It was his PCV that caused the loud whistle. Blown turbos have more of a dentist drilling sound. I’ll happily get back to you about what’s wrong with it in a week.

Just going off of what you wrote, bud… “I noticed a significant loss in power, especially under acceleration”. Again, maybe your mind was playing placebo games with you, but PCV failures don’t have that symptom.

I’m also not definitively saying it’s blown turbos. Either way, there are extended warranties for both failures, if you meet the requirements. Call the dealer to verify

When my PCV failed there was an astounding loss of power.
Also strangely enough someone commented my car sounded louder, like I had an exhaust installed. Very weird, but it all went away when the PCV was fixed.

Nothing to note when mine did. I personally had the whistle, but did not have a CEL. Guess we should put a poll out there lol

Your car has gremlins. From the AutoZone website: "When your PCV valve is malfunctioning, it throws the air to fuel mixture out of balance and can lead to poor performance and rough idle, as well as misfires."

Interestingly, AutoZone mentions that the signs of a bad PCV valve vary depending on whether the valve is stuck in an open or closed position. Maybe the AZ engineering types can explain that.

Interesting point. (stuck open vs. stuck closed).
Could be interesting. AFAIK I don't think anyone has dissected one to determine the root cause of failure.

Mine has also lost an astonishing amount of power and is a whistling smoke machine. perfect timing for everybody's Christmas shutdown
