Thank you so much for visiting our page.  Hopefully the info below is interesting and helpful.  If you find this info useful we would really appreciate your support.  We offer this along with many other helpful DIYs to the VW and Audi community.  The only thing we ask for in return is your support when you are ready to make a purchase.  Your support allows us to continue to commit the resources to create pages just like this one.
We have a video as well as a write up (found below) to show you how to replace the Volkswagen 2.0t TSI PCV Valve

 

 

 

The PCV valve on the TSI engine is bolted to the top of the cylinder head. This is the component that helps to evacuate oil fumes and recycle them back into the intake system in order to reduce emissions. But when they fail, you can get some various symptoms.

 

Take a look at the noise the PCV might make when it goes bad

 

When this valve fails, you may see the following:

– Rough idle, high idle or surging idle.

– Possibly strange intake noises at idle(whistle, air surge sound)

– Fault codes P0300-P0304 – Cylinder misfires

– Fault P0171 – Bank 1 system too lean)

– Fault P0507 – Idle air control sys. RPM higher than expected

Tools needed to perform this repair:

– T30 torx bit and driver

– Pocket screwdriver or small pick

 

 

This is for replacement of the Volkswagen 2.0t TSI PCV Valve. You may be looking for the previous part number 06H-103-495-A or 06H-103-495-E. This part number was replaced by 06H-103-495-AC as it is a newer version of this VW TSI PCV Valve.

 

 

1. First and simplest, remove the engine cover on the top of the engine. To do this, you’re just going to pull up slightly on corners with even pressure. I like to start from the front corner sand then do the back.

1

 

 

2. Next we will disconnect the PCV vent hose back to the intake manifold. To do this, I like to uses a small pocket screwdriver because the clasps don’t always like to let go. Just be careful with pressure or you could break the side tabs on the pipe.

2

 

 

To keep the hose out of the way during the repairs, I just spin it forward towards the front of the car like the picture below.

3. Disconnect all ignition coil packs to get harness back out of the way. As we know, these connector clips can be rather difficult to get to let go. Again, I like to use a small screwdriver to release the clip inside the connector. After the “click” of releasing the connector, just slide it straight back a little.

4. Remove ignition coils #3/#4 and set to the side.

5

 

 

 

5. Around the perimeter of the PCV valve, you will see all the T30 torx screws. Removed them all to free up the PCV valve. Total of 10 screws. When you tighten these you will torque them to 11nm.

Find these Torx Screws HERE

6

 

 

 

6. Carefully lift the PCV valve up and slide the rear dump tube out. This tube attaches to the turbo inlet pipe and does not need to be removed. Just push it off to the side and you will insert it back into the new PCV valve.

7. Make sure to clean the surface where the sealing ring around the PCV valve where it seals to cylinder head. Once you have the part off and to the side, you should be left with these 2 images….

9

 

The circled valve is the actual flap that separate the oil system from the intake vacuum.

 

 

8. Assembly is pretty straight forward and just the reverse of the removal process. Once completed, be sure to clear DTCs if needed and check to make sure there are no oil leaks or air leaks from the area around the new PCV valve. Ensure that all the grommets are present on the engine cover. Shown circled below.

Congratulations….you have now successfully replaced your PCV valve.

    This does not match the view of my 2008 Passat Komfort, 2.0 Turbo. If I could attach a photo, I would be able to show you the difference.

    Whats the cost for DYI? I need to find tools as well. I’ve heard folks on the forum say its a $130 part and 30 minutes of your time to repair compared to VW holding your car hostage all day and double the cost of DYI. Is this true?

      We have links to the part in the description above. Please check out the video it shows you how to replace the part and what tools to use.

    Hi, i have a 2009 golf gti, and recently i had problems with extremely bad idling, where it sounds almost as if i had a car thats cammed lol, but it would go from 1k to almost stalling and nonstop idling jumping it cranks and turns over everything works fine but my idle is horrible, could it be my PCV valve faulty causing the problem? Thanks!

    • Paul Barrett

      Josh

      It is very possible that the PCV valve is your issue but it is tough to say for sure. If the PCV valve is stuck open you may expect a rough idle like that.

    Hey Paul, 09 GLI here and I’m thinking I may need a new PCV but not sure since I just replaced the Rear Main seal, all my codes are gone but now I boost at 3psi. Is that a PCV symptom?

    • Paul Barrett
      |

      You could have a PCV valve issues but it could be other things. Its really tough to say, as your vehicle really needs further diagnosis to pinpoint the issue.

    can someone please post the PCV replacement diagram for the 2005 VW Jetta 2.5L

    Comment for 2.0 TSI engine:

    For some of these issues, the problem can be resolved by replacing just the diaphragm that sits on top of the PCV valve assembly. The diaphragm part is under $50 in cost whereas the cost of the whole PCV assembly can run over $200. The diaphragm cover is designed to go on but only come off with great difficulty. The diaphragm cover is the black round structure in the bottom center of picture 5 of this explanation. If you can get the diaphragm along with the cover – or if you can find a way to get the diaphragm cover to come off without damaging it (I could not), you may be able to solve your problem just with replacing the diaphragm.

    The diaphragm consists of a metal spring and a rubbery seal. On mine, there was a hole in the rubbery seal, and it appears that was the only thing wrong with my PCV. Do note that the orange valve on the underside of the PCV assembly can also go bad, though, so if replacing the diaphragm doesn’t solve the problem, then the whole PCV assembly will need to be replaced in order to get a new valve.

    • Paul Barrett

      We have heard similar feedback about replacing the diaphram by itself. It was never intended to be replaced, and we believe for this reason it was tends to leak.

    Does anyone have photos of the pipe that is disconnected and reconnected (rear dump tube) is this the part that’s visible still before the valve has been lifted off the engine. Or is it an internal pipe that is only visible when the valve has been lifted up

    Hi!
    I own a Tiguan 2.0 TSI that is consumming to much oil. About half a liter every 2000 kms. Would the replacement of this PVC valve solve the issue? if not, what can be the solution?

    Thank you!

    • Paul Barrett
      |

      The PCV valve could be your issue but in the US VW considers 1 qt every 1000 miles to be within the limits of normal consumption.

      • Alejandro
        |

        Thank you Paul!
        My VW service in Argentina did not give me answers about the issue. The only thing they did was taking an oil sample without any comment!!

    I have a 2007 GTI and it has developed a squeal sound only under load between 1500-2500 rpm and is intermittent. I have replaced all belts and pilley/tensioners timing belt water pimp and DV valve and still have this noise. The car performs fine and I have no codes. Just this loud squeal. Do you think it could be the PCV? Or do you have any other ideas?

    Thank you

    • Paul Barrett
      |

      Tough to say without hearing it but the PCV seems like a likely cause.

      • |

        Hi Paul, my 2012 GTI is making the same noIse as in the video. After dealer diagnosis, I replaced the PCV myself following your instructional. However the noise is still there!! The same as Erik, intermittently under load around 1500-2200 rpm. Any thoughts of what to check next? Would the seal on the back of the PCV connecting outlet possibly need replacement?

        • Paul Barrett
          |

          I took a look an didn’t see a purchase from us. What part did you replace and where did it come from?

    Have had a faint whistle noise that I could hear in the cabin but sounding like a vacuum leak for about 3-4 wks. Got a lean code, checked the pcv diaghram and it was torn, replaced it, whistle still there so replaced entire assenbly. Whistle still there. No more error codes. Runs pretty good but seems to be surging a little at a constant throttle on level or under slight load. Also highway mpg dropped down 4-5 mpg. The whistle is pretty much constant with only a slight change between foot-off idle and touching the throttle at all. Otherwise whistle sound and volume stays constant throughout the rpm band and load until i get to speed where road noise may be drowning it out. Oh, and it doesn’t seem to whistle when cold, only as it srarts to approach operatjng temp. Think i could barely hear the whistle under the hood today but am not sure. Ir cerrainly isnt loud on the outside of the cabin. Oh, and it is not the heater fan, that is turnes off and can hear the whistle inside. No oil leaks at rear main, ony used about a half quart of oil in 5k miles berween changes up to this point a little more oil consummption seems at least before replacing the Pcv, not sure now. 85k miles. Any thoughts or suggestions? HELP PLEASE!

    Great DIY. Is there any way to test the PCV valve to see if it’s working 100%? I don’t have a CEL but it’d be nice to be able to check somehow, perhaps with Vagcom.

  12. Joel
    |

    I have a 2012 GLi and put on a new PCV valve. Now the cars leaking oil… Any ideas?

    Can I take the PCV valve off and back on without worrying about a new gasket?

    • Paul Barrett
      |

      Yes you should be able to take it off and reinstall. Where is the leak coming from?

  13. |

    Josh P. and Paul. I also have a 2009 GTi and am experiencing the extremely rough idling, low oil pressure light, I have a small oil leak, but the engine oil level is fine, epc warning light and the blinking check engine light. I just replaced the pcv component (thanks for the GREAT DIY)…it did not fix the problem. I have had the ignition coils replaced about a year ago along with a new intake manifold, as the flaps in the old one was in PIECES! So, I am at a loss right now as to what the problem is THIS TIME! I am so disappointed in VW and will not be purchasing another…this is my second GTi. I am trying to hold off taking it to the STEALership, but I’m losing hope. Any ideas or suggestions? I do not have a VAG scan, but am considering purchasing? Thanks again for all the great videos, Paul!

    • Paul Barrett
      |

      A VAG Com is not likely to help you at this point. You will need to bring it to someone to have them track down by you have an oil pressure issue. You should not continue to drive the car like this as it could cause further damage.

    I have a 2008 volkswagen passat 2.0t . rough idle, pulled the pipe off going to the pcv valve and covered the intake port up and the idle cleared up. replaced the pcv valve and it ran fine for a little bit but the same rough idle reoccured . replaced the pcv valve again only to have the same issue. also noticed there a lot of oil under the car. its could be the rear seal. what could cause the pcv to fail and what to i need to check next.

    • Paul Barrett
      |

      It sounds like you might have a rear main seal leak but you should have someone help confirm this for you.

    I have an 2010 Audi a4 b8 2l tfsi. After having pistons and rings replaced to fix oil problem, the epc light comes on intermittently. I cannot state under what operating conditions. The dealer indicated the pcv valve (oil seperator) had a leak and i replaced it. The codes were reset but still the epc light comes on intermittently. I cannot hear any noises and the car runs well. The dealer said code was unmetered air into air intake. Any ideas to find the problem would be great thanks.

    • Paul Barrett
      |

      Sounds like you will need to track down your vacuum leak. You should consider having it properly diagnosed by a shop

    2010 VW CC 2.0T. Just replace the HPFP, control module, in tank fuel pump last week and yesterday the CEL lit up and got a code: 08583. What else could it be?

    Hi Paul, I have a 2006 Passat 2.0 turbo. I have recently experienced seeing white smoke come outf the exhaust and from the smell it is certainly oil burning. Also, i have to replace a lot of oil very frequently. The engine has also lost power; when I press the gas the car does not take off ask it used to. I am thinking it is the pcv valve. Could this be the case? Please advise. Fred

    • Paul Barrett
      |

      Its possible but its tough to be certain.

  18. richard

    Paul, thanks for the video. So after replacement is it necessary to recalibrate?

    • Paul Barrett

      You will need to erase the faults if you had some originally

    Thanks, this was very helpful, took me about 30 minutes, and the problem is gone!

    Hi I replaced my pcv valve it was a tare in the diaphragm it ran good for a day the surging idol was gone and the check engine light cleared the very next day the symptoms were back and the check engine light came back on could the be the seal on the bottom that sits on the valve cover? I’m really stumped feel free to email me so I’m sure to see your response thank you

    • Paul Barrett
      |

      Tough to say. Its possible the PCV valve was never your issue to start.

    Hi Paul,

    i have Audi A3 18.tfsi 2007. I have a fault code 0171 for very lean trim with check engine light. I have checked all parts from fuel pressure, MAF, electrics, looked for air leaks and nothing wrong there. My engineer can’t tell 100% what the problem is. Could it be PCV or N80? Thank you in advance

  22. Angelo
    |

    I recently had an oil change for my 2007 Audi A3. The next day the smelt like something was burning. Smelt like an electrical burn or possibly oil burning. There are no indication lights on the dashboard nor is the oil low. Not sure if this has any relation to the PCV?
    Please provide your opinion at your earliest convenience. Thanks for your cooperation.

    Best regards,
    Angelo

    I have replaced the PCV on My 2013 Audi A4 1.8 TFSI but I realized that after replace it still have suction at the oil filer cap when I remove it the idle will go a bit higher. What I have done wrong? I cleared the engine light so far still hasn’t come back
    The code I had was P227900 intake air system leak & P006800 MAP/MAF – throttle position correlation

    • Paul Barrett
      |

      If you still have that issue you have going to have to track down where your vacuum leak is.

    Paul,

    Having p0300 through p0304 issues along with rough idle. I know that plugs and coils are fine. No whistling noise from engine. Since I am getting intermittent misfires on ALL cylinders does this sound like PCV rather than injectors? Of course I’m much more willing to start with PCV first!

    Thanks!

    • Paul Barrett
      |

      This is more likely to be a vacuum leak than injectors since its on all 4 cylinders. The PCV valve could be the cause but its tough to say.

    Hi Paul I’m having an issue I hope you can figure out I had the dame codes of too lean when idle and vacuum leak. I changed both the pcv and rear pipe with the latest revisions and reset the fault codes but shortly after they came back on again. is there some explanation?

    Forgot to mention my vehicle is 2.0 fsi engine

    I just checked it and you’re right it is broken right at the location your video stated it would be. Ordered the brake booster pipe right away thank you so much I’ll update if problem fixed

    I replaced the pcv it fixed idle problemn now it’s leaking oil around rear main seal .what could be causing this?

  29. Jay Serrano

    Updating as promised: after installing the vacuum pipe for brake booster I’ve received no C.E.L so far. (two days and counting of driving as opposed to just 20 minutes prior to install) Thank you again.

    Your video was great. I replace the PVC valve on my 2010 Passat with a new on from your store without any incident. However the engine light is still on. Does it take some miles/time for the system to clear the error? Or should a new valve (if that is the true issue) fix the problem and shut the light off immediately after starting the car after the install?

    • Paul Barrett
      |

      You will need to erase the faults with a scan to turn off the engine light

    Hi,
    I have a 09 Scirocco, 2.0 TSI.
    I have a noise coming from the engine which I can only describe as a duck quack or cat meow.
    I have heard it may be the PCV Valve but I don’t have any of the symptoms i.e. error codes or lumpy idle.
    can this still be the case for PCV valve failure?

    Thanks

    • Paul Barrett
      |

      Its possible but tough to say. Thats not really enough info to give you any actionable advice.

    Hi, Paul.

    So I’ve been going back and forth with my dealer on what my issue is.

    I will first start off by saying that I am rather heavily modded. I’ve got about every bolt-on I can with the stock turbo, including Stage 2 performance software on my 2014 Mk6 GTI.

    One day while cleaning up my engine bay, I noticed excess oil seeping out of the rear of my valve cover. I know this is normal, but this was a little much. It began to ‘cake’ on, for lack of a better term. I then noticed more oil seeping from around my rear main seal. My CEL was on at this time with a P2077 (system lean off idle).

    Now after some reading and watching (HumbleMechanic videos), I had come to the conclusion that I must have had a faulty PCV valve, causing my rear main seal to leak.

    Took it into the dealership and (after I had to take it back home to put the stock intake back on), I received a call informing me I had a leak at my rear main seal. Cool, fixed up and ran better.

    About 100 miles later the same P2077 code was back. I called the dealer and brought it back in. The shop foreman basically said the pressure has to relieve itself somewhere, so that why it’s leaking out of the valve cover. I went to pick it up and he had left, so I spoke to a different tech who thought it could be my fuel pump. Brought it back in two days later and sure enough, low fuel pressure. New fuel pump, module and fuel filter installed.

    I go to pick up my car and there is STILL a P2077 lean code. Now, the very first time I dropped it off, I told them that I believe I have a faulty PCV valve causing my rear main seal to leak.

    For some reason they are discounting the thought of my PCV valve going bad. I have 39k miles on the car. I recently had a catch can that blocked off the vaccumm hose portion of the PCV.

    Do you believe I indeed have a faulty PCV valve? Is there a real issue with my block-off that would cause more leaking than normal? HumbeMechanics video on the PCV valve evens states to block it off to reduce the risk of leaks.

    Thought?

    Thanks for your time.

    • Paul Barrett
      |

      It sounds like you dont have a PCV valve on the car. Is that correct?

      • Anthony
        |

        I do (Mk6 GTI). For a period of 500 miles while running an ECS Tuning Catch Can (now removed while its at the dealer), I had capped off the vacuum ports from the PCV and manifold (included in kit).

        I had watched HumbleMechanic’s video on the PCV valve and how they fail. He mentioned lean codes, leaking rear main seal etc., my symptoms. He then said that I could cap off the lower portion of the PCV valve to reduce the chance of oil leaks.

        The dealer is blaming those caps for my excessive leaks at the valve cover, even though I only had them on with the catch can for 500 miles. I am thinking that because of my leaking valve cover, lean code, and leaking rear main seal; it has to be the PCV valve that is at fault, no?

        Thanks again, Paul. Really appreciate it.

    Hey guys, I have been chasing an issue for a while that’s killed 3 DVs, had system to rich at idle, just recently had all 4 cylinders misfire (code p0300-304) and then a p2279 which was leak at intake or something like that. With the car off, I can’t blow through the front, but the rear I can blow air straight through. I also cannot feel a good stream of air from the bleed hole on the pcv, so possibly the diaphram is torn? If I remove the dipstick, there’s no change in idle. If I remove the actual oil cap, a it pours out. Does this sound like a shot pcv?

      • Evan
        |

        Ok great, glad someone could give me a straight answer. I’m also running 26 psi so I guess a catch can might be the way to go?

    Hi,

    I have a 2007 Audi A3. I got a P0301 code that i cleared and it never came back over the last two months. I do have a rough idle, the car vibrates while on D and its getting worse. I see oil residue / seepage at the bottom of the air intake pipe (after the air filter, down where the is a small pipe fitted and closer to the engine). The car slugs and then suddenly speeds as if there was something blocking the speed. Moreover, the car vibrates very bad while releasing the brake and accelerating. Lastly Oil level goes low (warning) around the 5K mark.

    I have heard that changing the PCV on these 2.0T FSI engines have improved the symptoms. What would you suggest?

    Thanks in Advance.

    • Paul Barrett

      Sounds like you have a misfire or vacuum leak you will have to diagnose whats going on.

    Hello I have a 2013 Gli. I had recently had a atmospheric DV spacer on my car but I took it off bc it was leaking oil. Soon after I took it off from my stock DV under hard acceleration I now have a whistling noise. What could be the issue and how do I fix it???

      Could be a boost leak but its tough to say for sure.

        Hello, I currently changed my pcv valve because I had suction from the crankcase (through dipstick and oil filler), and rpm would drop when I remove them. But the problem still occurs… What other possibility could it be?

    Is there a part number just for the pcv gasket in the post?

    Hey Paul. Quick question? I have a P0236 code that comes and goes periodically. Wanted to know if I should change the DV valve or PCV first? I doubt its a vacume leak from a line since it come and goes periodically..

    My 2010 Jetta 2.0T had a P2187. I took to VW and they diagnosed as bad PCV. I changed the PCV valve myself and the P2187 came back as well as a P2279 now. The car has a smooth idle in park but notice while in drive it surges. I also notice that when starting the car after it has sat for a while it seems to crank for 5-8 seconds before it finally starts. These conditions were present even before the PCV change as well. Any ideas?

      Start by making sure you have the correct PCV.
