Beck/Arnley 045-0383 Crankcase Vent Valve

Installed on 2005 Audi A4 B7. After replacing this PCV valve, check engine light went out and everything was good. Unfortunately, the fix only lasted about 2 weeks, which made me question if that was the original problem. And vehicle made a loud whistling noise. I ordered a new one (OEM) from ECSTuning, along with a new seal. After a couple of days, check engine light has gone out and the whistling has stopped.I suggest you spend the extra $$ to get a better quality unit or OEM.

i bought this one for my Audi a4 2.0T quattro. from the the get go I noticed a small check valve inside the pcv valve which caused me P0171. I realized that I bought the wrong part and replaced with my old one again.Make sure your build or chasis number matches along with part number. Old and updated parts may look same but the check valve makes all the difference.

Does not fit 2008 Audi A4 size. This is the older style that is for the Audi A4 prior to 12/2005

Did not include the pictured gasket. Had to reuse the old gasket, and now have an intake air leak, a miss and a MIL.Will not buy this brand again.

Fit perfect on my 08 B7 A4. Fixed my lean bank 1 code. These commonly fail. This is a good replacement if it's the right revision for your car. Before replacing make sure it's the same exact part.

I bought the first one and installed it into my car. I only drove the car for about 45 miles before it got defective and stopped working. I returned the part and got another one and the same thing happened. I have returned to get my money back. Do not buy it

This part is a cheap knockoff of the correct part. I bought 3 to have on my shelf at my repair shop, and all 3 were failed units directly out of the box. When trying to reach customer care there was no answer.
