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

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for the previous part number 06H-103-495-A or 06H-103-495-E. This part number was replaced by 06H-103-495-AC as it is a newer version of this VW TSI PCV Valve.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.

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.

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. 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.

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….

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.
