Review on 🔧 Fix & Restore PCV Diaphragm with Dorman 917-064 Repair Kit for Audi/Volkswagen Models (OE FIX) by Joseph Lang

My 2009 Audi A4 B8 was showing engine codes P2187 (System Too Lean at Idle (Bank 1) DTC) and P2279 (Leak in Air Intake System). After reading many websites I have read that a common cause of these trouble codes in my car is a ruptured PCV membrane. After reading that the cap was difficult to remove and a lot of people broke it, I decided to just spend $15 and order this part regardless of whether the membrane was broken or not as I may need a new cap . After he entered, I opened the lid (cracking it in the process) and sure enough the diaphragm was ruptured. I used the existing spring and seat where the spring meets and just used the new diaphragm and cap. Cleared error codes and has been working great ever since. I agree with some of the other reviews that the diaphragm appears to be a little thinner than the OEM part, but I don't mind spending another $15 if that turns out to be the case.
