PCV Valve
« on: March 05, 2012, 09:13:32 pm »
I recall reading that depending on what revision of PCV you have on your car, when you replace it you also have to replace or do something else - another check valve somewhere else?!  Sorry, thats a bit vague but I'm sure I read something of the sort here before.

Anyway, I'm looking for a bit more clarification on this if anyone can assist?

With the newer pcv's you also have to have a rear check valve that included in the rear pcv hose.
Early versions didn't come with the rear pcv check valve.

Ah ha...

I replaced my PCV about a year or so ago and given I have an early 05 GTI its more than likely I don't have this doofer.  Where abouts is this pipe, does anyone have a P/N and what would the symptoms be of not having the extra check valve?

Must say the car seems to be going fine with no particular issues...

This link show you where the rear breather hose with check valve is located. With your original set up the breather hose didn't have the check valve.

Does this still need doing if you fit a catch can. Will it help? Or only needed for the revised pcv stuff?

Thanks

The new part numbers are 06F 129 101 P for the PCV and 06F 103 215 B for the rear check valve.

The rear check valve is not needed when fitting a catch can but is needed if fitting the latest revision PCV if your car is older than an 07 plate.  I removed my catch can and refitted my PCV valve.  My reasons are contained within the link below.  I find that my engine runs smoother now with the PCV fitted than it did when I had the BSH fitted.

What happens if you don't fit the new hose?  I've not had it for over a year and I can't say I've experienced any issues.  I will change it but curious about what the benefit is?

If you want the latest PCV that will work on the earlier engines without the rear check valve you need the 'N' revision.  They are the same as the P only they work without the need for the rear breather hose as I believe they have stronger spring inside.  I am getting the N revision so I havent got to bother fitting the rear breather hose :jumpmove:

That's good as I have done 3,500 miles on my revision N having changed it last September!

The part number for early VINS is 06F129101N and the rear breather hose is 06D103213G, which does not have a check valve in.

If you have a small mirror then you can check the pcv itself for the part number/revision.   :smiley:

Would a duff PCV throw up an error code on VCDS or not?
