If you own a similar engine,


then hopefully this will save you some time.
My check engine light recently came on and sucking noise when removing dipstick. So took it in for diag. Shop said the PCV valve has failed but should be warranty. Took car to dealer, they said the campaign for the PCV does not apply to this car so they would have to charge me $130 to diagnose it again, plus labor, plus the $90 part. I purchased the part and went home to replace it myself. Found out they sold me the PCV for the FSI motor (2008.5 and older). Crap!
Did some internet searching and found the proper PCV (part# 06h-103-495-e) for 2008.5 and newer.
Sells for $190 at dealer! Damn! Took the one off my car and disassembled the diaphragm.

Torn diaphragm.

More Googling found just the diaphragm kit (part# 917-064) available at Autozone for $20. So ordered it, should be here tomorrow.

To be continued...

 

Got the new part. The diaphragm and cap are the same but the spring and spring plate are different. The spring is too strong and the plate has clips for the spring.
Do not use these new parts!


Only use the new cap and diaphragm.
Started the car and no more sucking noise when pulling the dipstick! Sweet.
FYI. No need to remove the whole PCV assembly. Just get a small flat-head screwdriver and a hook pick to carefully pry the cap off.

 

I just wanted to signup/log in to thank you for this thread. It was exactly what was wrong with my 2.0t A5. You probably saved me 200+$! However, I'm not 100% fixed yet due to the diaphragm part arriving monday, I'm very confident this is the issue because the diaphragm was torn. Thanks again!!
