OEM VW/Audi 2.0t TSI PCV

 

 

The PCV valve on the TSI engine is mounted on top of the valve cover.  When the PCV valve fails it will often result in a loud howling or squealing noise coming from under the hood.  It is quite surprisingly louder than you would expect.  Other symptoms of a bad PCV valve are a possible check engine light or rough running condition which could produce fault codes P0507 or P0171.  Please note that a bad PCV valve could cause the rear main seal on this engine to fail (See Below for more info), and for this reason you should be sure to replace your PCV valve with a high quality product.  VW has updated to a newer version of this part and the most current version can be found HERE.

We also offer a more affordable version of this 2.0T TSI PCV Valve HERE

The old revisions of this part number will be any of the following.  06H-103-495-E, 06H103495E, 06H-103-495-A, 06H103495A

    Hi,

    Is that possible that I have an excessive oil consumption because of a failure PCV, even if it´s not making any noise, or have a diafragm issue? Could it be just a clogged valve inside?

    Thanks

      Yes its possible it can fail and not make noise. This is just the most common way they fail.

    Hey Paul,
    I don’t have a rough idle like most people or high whistling sound from the PCV area, but I did notice that there is air continuously coming out of the bleeder valve on top of the diaphragm. Is this normal?

    Thanks

      Tough to say. Do you have fault codes?

    What is the difference between the more and less affordable PCV valves? OEM vs aftermarket?

    • Paul Barrett
      |

      Generally the overall quality and longevity is better on OEM parts, but from us both of those valves carry a 1 year warranty.

    Could a pcv problem be related to a p2187 code I have on my 2010 CC sport? I can’t find the vacuum leak anywhere on the car.

      Yes this could be a bad PCV valve causing this issue

    I have an 08 Audi A4 . When It is in drive it has vibration. When it is in park or Neutral it is fine. Could this be my issue?

      Its really tough to say. Its possible that a PCV valve could be your issue but more diagnosis would be required.

    Hello Paul!

    I have a 2.0 TSI and I was told by a dealer that I had a bad PCV valve and it needed to be replaced. CEL was coming on for Bank 1 too lean. I looked into it, found your products and decided to do the work myself. I decided to buy the Prexa version of this valve. After installing it, the code was still being thrown. While investigating the problem, I found that I could cover the bleed hole while pushing down on the top of the diaphragm cover, and it would stop the vacuum leak and the engine would run normally. I’ve done a good deal of research to try to understand what that indicates but can’t quite figure it out. Any thoughts? Still a bad PCV valve?
    Thanks!

    Any update on Josh’s issue above? I have the exact same issue and I have an OEM pcv part ready to install. I am just wondering how it turned out with his issue as it is so similar to mine.

    I have a 2011 gti and was wondering if my pcv being bad would cause a jerk in shifting around 3-4k rpm? It is tuned so im thinking maybe the lack off boost is tricking the ecu to shift weird. The car sometimes also will feel like it does not want to move when on the highway in “m” mode if I go WOT, then it will seem to let boost hit and take off. I tried the oil cap removal while the car is idle, and the car would run a little rough and high in idle but not crazy. Does this sound like a pcv?

      Tough to say for certain. Does the vehicle have fault codes?

    Do either of the PCV Valves have a warranty if bought from this site?
