How to diagnose and replace a VW / Audi 2.0T, 1.8T PCV valve

You can find our upgraded PCV valve here: https://www.rkxtech.com/collections/pcv-valves/products/rkx-vw-audi-2-0t-tfsi-upgraded-pcv-valve-repair-kit

Albright we trying to participate in 2022 with our first short! We will be trying to make more as time goes on. Let us know what you would like to see for future videos.

Testing for a ruptured PCV valve is simple! If you feel vacuum coming out of the top vent hole on the PCV valve cap your PCV valve has an issue. This vent hole is simply a breather to let the PCV valve move up and down freely. You will never feel / hear vacuum from it when it is working properly.

is it feel suction or how

@Retodd._. says:

So basically what he’s checking for with his fingers is suction. You should see a hole at the end of that lifted line in that part and if you put your finger there you shouldn’t feel any suction, if you do there’s a leak. There may be other causes for it but I am just going to try to replace the cap as well you may have to replace the entire Pcv valve or it may be something else

Mines does that but the diaphragm isn’t torn.

@brandypresley1869 says:

So were u getting air or no air when u touched the hole on top

@felixtovar4609 says:

So how do you diagnose it?

@jeffreyswarts1524 says:

My Golf 6 Gti. Throw out rich code P0172. Did feel air escaping from my PCV. Can this be the culprit? I understand that a good PCV should not have any air escaping

@theGinthebuilding says:

This is misleading.. they fail in other ways even worse than this causing possible rear main seal failure

Vou dar uma dica aqui. É difícil pra desmontar, e pra montar é bom usar um martelo pra fazer o encaixe. No motor 1.8T 2014 da Audi, o respiro fica virado pra direita assim como no vídeo. Espero ter ajudado!!

@dylanhubbard4599 says:

how much was that part? vw tryna charge me 200ish

@yung6moke870 says:

it sounds the same tho. i have a 2010 passat and i got a new turbo, new pcv, put new injectors in, new sparks and coils and it still runs rough as shit. prob just need too rebuild the head and clean the lifters.
