yup, wanted $650 from me 2011 Audi A4, picked it back up and made a good relationship in the process so no charge and gave me the part number, picked it back up an ordered the genuine $200 part on sale at ecs for $150, the part made it in today and it looks like its going to take me longer to find my tools than it will to get this done.

They wanted to charge me $450 to do it. Found this video and I did it myself. Part cost me $135 but hey, better than $450

Winged Carbon 8 - I have a 2013 cc as well and replaced mine PCV \ it fixed mine but( the Humble Mechanic) if you don’t catch the problem soon enough it can cause your rear main seal to go bad .. that would have you leaking oil. The diaphragm in my pcv valve had gone bad , although my car does have 111K miles on it .. I’d like to know what the issue was with your cc.. thanks

@Nade Just ring your nearest Audi main dealer and ask for the parts department. Give them the part number and they order it from Germany. Took 2 days I think.

@Nade Cool, no worries mate . Simple to fit as well . 1/2 hour if that 👍

Neil Gauden going to work on mine soon.

Franklin Rocha Jr it’s sealed. I never really knew why VW did that. I assumed it was for air blow out if someone needed to bore it out and redirect.

I believe so, but you will have to troubleshoot. VW’s are weird in that it can be a number of things.

Possible fault cause - Incorrect main charge signal - Intake air system leaking - Fuel pressure too low - Volume supply of fuel pump too low - Mechanical fault in injection valves - PCV valve leaks - Cap of oil filler neck leaking - Leaks in exhaust system - EVAP canister purge valve mechanically faulty (hangs open) - EVAP canister purge valve output stage faults Check the gas cap too. Check oil filler cap as well.

The P0171 code on a Volkswagen Passat will often be thrown if the fuel injection system is not operating properly. Typically the code will be triggered by a lean condition in the engine. John Junior

John Junior Here are the typical symptoms that something is wrong when you have code P0171. Mileage- may or may not suffer depending on how much the air fuel mixture has changed. Misfire- If the air fuel mixture has gotten too far from factory specs, this can cause the Passat to misfire. Idle Issues- With the air/fuel mixture altered, the vehicle can idle erratically as the computer compensates to keep the engine running.

Thank you

Hi TB. I live in the UK and had the same issue on a 2011 B8 A5 2.0 tfsi. The first fix (like you've had done) works to a degree, but fundamentally, Audi messed up with the piston ring material on petrol vehicles vehicles between 2009 & 2011. I had to have my engine rebuilt by Audi, with new pistons, rings, con rods etc fitted. That worked a treat and 90,000 miles later the engine is still using minimal oil

Paul Perlstone check your spark plugs. it could be that you have oil in the plug bores.

Thanks , the epc light is on as well

epc can be a couple of things. Throttle body traction control, pedal issues. you should get a diagnostic tool obd2 reader to see the faults.

I changed the plugs, They were the original ones. Full of oil, No miss fire , No check engine lights. Than You very much you saved me big bucks.

Same issue with mine every time I try to replace it seem to run worse the stock one, have you figured it out?

@@khalidkhodair5832 I just did the same thing I would like to know how to fix it

Chutneyperson it kept doing it with 3 more try’s and my car was leaking from the Rear main seal and after I replaced it the car stopped acting up and the check engine went away like If nothing was wrong with the pcv, you might want to look if your car has a leak anywhere that could be causing a vaccume leak

@@khalidkhodair5832 Yeah, mine turned out to be the rear main seal too and there was no way replacing the PCV after the fact was going to fix that. It turned out to be an incredibly expensive repair.

@Mudig it was horribly expensive and time consuming and a month later my car started to leak again but very very little compared to how it did before, but still no check engine light or hissing noise from the pcv so at this point I give up lol because I can’t even begin to understand why it’s behaving like this

@RickReviews thanks bro

The dealer just told me I need mine to be replaced (car actually leaking oil). They want to charge $500. The parts doesn't seem that expensive. Mine is 2012 CC sport 62k miles. Let me know if the cost if you pay to get it replace...

...said my pcv breather valve leaking

Christopher Vlachos wow! sorry to hear that. it's not a cheap job. what's the malfunction indicator light mil code? the pcv can blow the rear main seal but as for the turbo...I'm not 100% sure. I was told that it's a possibility by the dealer mechanic. what type of turbo did you buy?

no codes at all in the car I had it replaced and the new one is smoking a little bit I was wondering if it could be the oil in the exhaust because it only smokes after it has been running for a little while but I dont want her to blow it again The last one was a borg warner

no code or check engine light. might be the head gasket leaking on to the turbo and that's where the smoke is coming from

Daily Ritual it is oil not antifreeze

Nik P mine seemed instant.

Jim Webber really well. Surprisingly!

Yes, but the alignment pin usually breaks due to the wonderful German plastic and you could end up with a vacuum leak that you don't want. Best to replace if you can.

Carlos Rueda the PCV is a breather system.

The problem i have is after i change it, i realize that when i turn on the engine and i open de oil cap it sucks a lot of air and the engine wants to turn off. Is that normal ? What could be it?

Carlos Rueda too much vacuum

Yes, the nail was there solely to prevent the air from escaping and making the engine shudder.

Daily Ritual so then air is not suppose to escape from there

It sucks air. I put the nail in there for that reason. Explained it wrong though. There is also a spring in the center that can get messed up too. What symptoms are you having?

Hanging rpms after coming to a stop, Rough idle, and codes p2187 & p0507

You see these cars are pretty tricky cause it can be the ignition coils, it can be carbon build-up or the flapper within the intake manifold. P0507 is air control. Thats what I would go with is the PCV but keep everything else in mind. How many miles do you have?

Ryan Pahl from how understand it. it's due to the pressure that's building up and causes the rear main seal to leak. I just had mine fixed last week. sucks balls and is around 1200$.

It does suck! I'll replace the valve myself because of this lovely vid but the upper/lower timing covers along with the rear main seal I'll leave to the experts. Not sure why the timing covers need replacing...

I am curious as to the time line with your rear main seal repair and when you replaced the pcv in this video. Did you have the seal fixed first....than you did this pcv repair?

Carlos Franklin that's exactly why I started to watch this video

Well, PCV can be responsable of a lot of problems. But to diagnose it can be very easy or hard (depends of your skills/tools). Usually PCV will cause vacuum leak or a lean engine (too much air for combustion) and it will cause problems. Bad PCV will have direct consequences in your Engine operation. These are typical symptoms (not exclusive) of a bad PCV that can be only one ou multiple of it: - A loud or noticeable whistle (the loudness depends how bad it is) - Very rough Idle - Misefires (can be only one cylindre or more) SPECIALLY in idle and very few or none misefires when you drive in higher load - Black smoke coming from exhaust (Oil Burn) - Engine Oil consumption higher than normal/acceptable - Oil leak in the PCV piece itself (sometimes can be nasty) - Less Engine Power and response in low revs - Poor gas economy - Hard to start the cold engine in cold weather (close or bellow freezing temps) If you can do the repair yourself (which is easy), it's fairly cheap. Exists 6 versions of this PCV (5 revisions). The last one, and the better at the moment, have this part number: 06F129101R

system too lean code P2187 because of this too much vacuum blows out rear main seal, or valve cover gasket. which costs ten times more than pcv

@@JoelinoPT I did got all the mention problems mentioned above. (I have a 2010 GTI MK6) one night after filling up my tank I got a check engine light. After connecting my obd2 reader I saw I had misfires in all the cylinders, I had poor gas (I was doing around 20 miles per gallon on premium [octane 93] and rough idle everytime I brought it to Parking. I brought it to the Volkswagen dealer and they wanted to charge me $450 for parts and labor. I got the part on Amazon for $100 [06h103495ah] (that's the last revision I found for that year/engine) and I'm planning on doing the change myself.

Sergio V shaking and loud hiss from the engine.

hey can you tell me witch one are the vacuum hoses

for the cover but Awsome video helps since im working on my a4. Thanks

Yeah I did my intake manifold also to clean the carbon build up but never filmed it. I wish I did, but I just wanted it done so I can get the check engine light off and pass the inspection.

Coool Keep posting bro

+Manuel Rosa thanks I'm glad this video helped you with your project.

According to the VW shop manual, the T-30 bolts securing the valve are 11Nm which converts to 8lb ft. (Of course it's academic since most torque wrenches are not going to be that exact anyway) Of equal importance, is the tightening sequence should be more or less a star or crossing pattern like when you're tightening up tires.

so if i change the PCV, for a new one, it should blow air?????

If I have vacuum from that bleed hole while the car is idling does that indicate a bad PCV?
