NOVAPARTS PCV Valve Crankcase Vent Valve Oil Separator for 2012-2018 Audi A4 Quattro Q5 A5 A6 Q3 Quattro Allroad 2.0T 06H103495AE 06H103495J 06H103495AK

My Audi 2.0T TFSI in my 2012 Q5 was misfiring when cold and at idle (not after engine reached operating temp). During diagnosis I discovered I could blow against the PCV valve in the hose coming from the intake and it would leak by the valve. The large diaphragm valve that is replaceable on the PCV was in good shape so I needed a full valve.Bought this valve, installed, and still had the cold misfires on all cylinders. The valve cover and timing chain gaskets had developed leaks due to the faulty PCV. As a Hail Mary, I replaced the timing chain gasket and used permatex to seal up the valve cover and Voila, it runs great! No more misfires or check engine lights.I highly recommend those with a cold misfire replace the PCV and address any oil leaks caused by the PCV at the same time or the engine will still detect the VCG leaks as intake manifold leaks. I hope this helps someone solve their mysterious cold misfires!Good luck!

Ordered part without a hassle and part arrived quickly. Installed and ready to go! 👍🏾

Oil separator pcv valve was easy to install and under $ 50.00 was a good buy when auto part stores wanted 2 or 3 times that amount.

I purchased this product May 18, 2023 and it has already went bad and leaking. Waiting to hear back about the warranty. Product has not even lasted 4 months.

Saved $130 and it works perfect! Finally smoothed out idle, got rid of 2 codes and engine warning. For those unsure if they have a bad PCV valve, remove engine cover, start vehicle then listen for an air leak. The round cover on PCV valve has a small hole on the side facing windshield. If you can feel suction or hear air hissing, valve is bad! Thanks again, part showed up in one day.

Fast shipping, good price.

Fits and functions like OEM in my 2014 Audi Q5. Car has about ~102,000 miles. I used to burn roughly a quart of oil every 400 miles, after swapping out my original PCV with this new one I have lost zero oil after about 600 miles.UPDATE: After about 3 months of use, my car started burning oil again. Although, not quite as bad as before changing the PCV valve..UPDATE 2: If you have an Audi Q5 or any Audi with a 2.0T engine that is burning oil like crazy, try a piston ring chem soak with B12 first before replacing your PCV. After many years I was able to figure out this was the issue with my car burning oil, NOT the PCV. The oil evac holes are notorious for getting clogged on these engines, and the piston ring soak was the cure.
