Dorman 917-064 PCV Diaphragm Repair Kit Compatible with Select Audi / Volkswagen Models (OE FIX)

Car started blowing blue smoke but I noticed it was happening on and off. I had my doubts about it being caused by the pvc. I ordered it and in less than 5 minutes installed it. Instant results! NO more blue smoke. Amazing!

easy to install,worked as stated.fixed my VW lean code. the old spring wore out shortened through time the diaphram was fine no cracks.

My check engine light in my Audi A4 came on a few days ago. I used Blue Driver (sold here on Amazon) to scan the ODB-II and got two errors back: P2279 Intake air system leak and P2187 System too lean at idle bank 1. I used Google to figure out what they might mean in layman's English. All the results pointed me to this product as the best fix for the money. The internet was right. Update July 30, 2016: Still working perfectly. Update October 1, 2015: This part has been doing its job perfectly for 30 days and I'm still happy to have saved the money. For the price, this product simply can't be beat. I would have spent $350 at an Audi dealer to solve my check engine light problem. It took me about ten minutes to install the replacement part. The old part, once off, definitely had a seal issue. This replacement fit perfectly. I am not a mechanic and I was able to install this sucessfully using two flathead screwdrivers. I'll update my review once I have had the part installed for a few months. I used blue driver to clear the codes 30 miles ago and the vechicle is running perfectly. The codes haven't returned. Update: April 27, 2016 - This product is still doing the job. No issues so far.

Good item

As Described

Well, I ordered this without further checks for my 2014 Jetta 2.0l engine, non-aspirated. So it's plane Jane. This Jetta engine does not have this type of PCV arrangement with this diaphragm. Wrong part. Wrong Amazon message that it supposedly fits my car...it does NOT. For those who have this engine type double-check your arrangement. There is a PCV tube ($58 from OE VW dealership) and it goes to a valve that's fused on the air intake pipe. If this valve is defective you have to replace section of the pipe ($225 from VW list price) from the throttle body to the inactive section of the air intake pipe that's connected to the air filter housing. I have random misfiring and as I have changed a few other parts the codes have changed. I replaced already the crankshaft position sensor with original Bosch part ($40) and the MAP sensor (Bosch $20). I wanted to change the PVC valve (apparently the entire air intake section with fused on valve for $225 )and also the purge valve (Bosch $20). Still waiting for the purge valve. My vehicle has 200,000 miles on it so replacing all of these is no big deal and needed to be done. It ran flawless for 200,000 miles until the EPC light came on (in conjunction with the check engine light). With this I also replaced the spark plugs. I can drive (it helps that it's manual) but have ~70% of the power which means it's a drag (no torque). I will replace the air intake section with the valve only if the purge valve doesn't fix the issue. It's a pain in the Ar** to find good experienced info on this. I am looking for a second car because of my mileage but the engine is still a good shape. I will fix this. Any ideas, let me know. I will post the final fix here and on a forum. Replacing the parts I have so far is just necessary anyway after 200k miles. the final fix was the ignition module. 100% power back. i have now 225k miles on it and really, my car has more power than ever like new plus.

Works great, installation was only about five minutes.

Work as the original good quality fit I recommend

After noticing my engine wouldn’t be affected when dipstick or oil cap removed. I order the dorman kit. Arrived surprisingly fast in 2 days. Install is easy and the product seems to seal and fit pretty good like Oem. I would recommend the use of pick tools for taking off the old part but I managed to get away with small flat screw drivers but be prepared to break it. The original part was so fragile it tore apart multiple times when I tried separating the gasket from the cover. The diaphragm on the dorman kit seems to be the same lenght as oem with more spirals. The engine was definetly being affected by the vaccum leak when removing the dipstick or oil cap after the the install of the new part. I haven’t further tested the product but as for now for under than 30$ fix I’ m a satisfied with the results. For reference car has 208k km.

works perfectly, highly recommended,,,

Works well

Big money saver, works perfectly on Golf Mk6 2.5 2012.

I have a 2010 tiguan comfortline. It fit perfect and was super easy to access and put on. Cheap fix for a rough idle and horrendous squealing noise that came from under the hood. Super pleased that it worked! Definitely recommend.
