I have audi a3 with 1.6L petrol engine that I believe it has a problem with the pcv valve and I don’t know where it’s located and the spare parts store don’t have my engine Diagram. Can someone point the pcv valve for me? I have attached two pictures that identical to my engine for you to see. Thanks in advance enter image description here

It should be this one. Seemingly it´s integrated in the part below the oil filler cap.

  • Thanks I will go to check the car now because it’s back and I will take pictures to the engine if I didn’t find it or the photo is not 100% matching my engine

  • I have deleted this picture because mine doesn’t have this pipe

  • still should be in the same location. this pipe in the front is just the oily back flow. If you order the new part, I´m sure you´ll recognize the form. justgermanparts.co.uk/…

  • Can you check the post picture because I kind lost how to install this valve if I order it and where it should go because there is no sign of place for it. Sorry to bother you but the mechanic guy did not help with that and he even mixed between the pcv and EGR valve

  • Changed the picture. Do you think it will do your car any good when you try to work on it, if you are so un-experienced? Don´t you have a friend or a self-help shop around where there is someone to give you a hand?
