Wow 8 years later and this is very very useful thanks brother
7 years after this video came out and it came in clutch. Easy diagnosis with this info and so glad it’s not my intake manifold gasket.
Thank you so much!!!!! I went through several videos that claimed to be diagnostic, but really weren't. You just clearly answered everything I was trying to figure out... Plus the added bonus of connecting my sudden oil leak. Wish I'd known that sooner. Time to get to checking my PCV!
You are by far my favorite mechanic on CZcams bro
Great Video exactly the issues I was having on my Audi B8 2.0 Turbo. Replaced and runs like new. I had been using oil as you mentioned as well. Thank you Kindly !
+HumbleMechanic .. I just replaced it this morning. Car started doing a loud screeching noise two days ago. After checking your videos and diagnosing the problem, I ordered the part from Deutsche and replaced it myself. Very easy DYI and fix. Thank you for all the help you provide to us VW owners. (we really need it, lmao).
You really saved me towing money and expensive no use mechanics ,who have been claiming that the sound comes from a faulty pulley or a worn fan-belt. Thanks so much...
I have been troubleshooting multiple error codes for at least a year to the point where I either wanted to catch our Tiguan on fire or put a Free sign on it. The PCB valve fixed it all! My wife treats me like a hero. I could just give you a huge hug man. Thank you for such great instructional videos.
your next engineered failure may not be as trivial... such as valve timing relatedcodes 😂
German engineers are doing their best to force drivers into buy Japanese cars... anyway it's still Bosch licensed tech regardless
👍🏻
@@glasser2819 I was thinking the same, I Like how he underplays VW parts failures, turbo wastegate,pcv, diverter valve etc. Keeps mechanics busy. Plus the magically brittle plastic german manufacturers uses is just hilarious.
Look how old this video is ;)
@@HumbleMechanic I went down the TSI rabbit hole.! :)
@@HumbleMechanic Hi mate my PCV valve works fine but the car has 200,000km. Would you recommend to change the PCV?
Great guidance, thanks :-) My SEAT had a hunting idle, 'too lean' codes, and a wheezy air sound after engine off. The PCV looked a bit different, but I was able to carefully prise it apart, and voila a ripped diaphragm!
Im here again my friend.
I been working on my 2007 2.0 T FSI
And everytime its a new code.since i did the valve replacment crazy but its truth
I dont know the reasons but im tired to spend a tons of time on this car .
The goods its you are there to show me posibles causes and how to fix the problem.
Tks my friend for this videos
Keep doing it .
Thank you so much for the video. It saved me from going after an O2 sensor and saved my wife a lot of money. The diaphram had a torn gasket. Luckily a local part store had the Dorman part for $30. Quick and easy fix along with cheap. Thanks a ton!!
+Jim Weck II sweet!!!!
Huge, huge help. My 2010 CC had been giving me the Cylinder 3 Misfire code several months ago. I assumed it was the notorious carbon buildup and not being ready to drop the cash for repair decided to experiment with a can of Seafoam. Problem solved, no codes for 3 months! A week ago my car died while backing out of the drive one morning. No code; effortless restart. ??? A few days ago I was hit with the P2187 code and a very erratic idle. Your mention of the whistling noise struck a note with me; I'd heard that sound off and on for about a month, always at idle after highway driving. It seems you have perfectly described my issue.
Parts are ordered. Thanks for saving me a lot of money at the shop.
The Seafoam usually works on most anything it fixed my sprained ankle on a ski trip once...after that your only hope is JB WELD.
Thanks . Clear explanation , i believe mine has falled . 2015 jetta 1.8t 42,000 miles . Small valve cover leak.
This video was great as its given me the confidence to tackle the PCV replacememnt myself. Perth Australia
Thank you Humble Mechanic! Helped today so much in fixing my PCV valve and thanks for including how to test it.
AWESOME!
@@HumbleMechanic Do you recommend a pcv delete on an fsi engine
Great video Humble as always. A week or so ago my 2013 gti started idle revving. It would go up to over 2k rpm at stops a couple times before returning to normal. (750 rpm or so) Seeing this video and others forum posts on this problem made me think the pvc was the likely problem. Turns out my local auto store carries just the diaphragm hockey puck sized part of the pvc. So with a little work i snapped out the old and just like you mention, the diaphragm was torn. Put in the replacement and its back to normal. thanks again for your vids.
My rs5 did the same thing right after I tuned it. And I recently had one night where it took a few times to turn over and smelled like it ran lean. Unfortunately mine requires 2 and they are like $600 total. Appreciate your comment. Pushing me to check this
@@theeinsuranceguy How do you smell an engine running lean? You can smell it when it's rich, because it'll stink of fuel. But I'm not aware of a lean running engine producing any particular smell.
This guy is awesome thanks so much. I’ve been searching for hours and this is exactly what my problem was. It fixed it right away
Thanks for this video, it made me focus away from a suspected leaky turbo shaft. I found a fourth way the valve can fail; mine had significant carbon build-up on the diaphram and seat. After cleaning everything is back to normal.
Thanks for posting, it helped me. My 2009 Passat engine (1.8 TSI BZB) was shaking badly in the morning after a very cold night outside and had misfire error codes. In the end, the PVC was ok, but the crankshaft seal to the gearbox was leaking. I think the PVC froze and built up pressure. I replaced the PCV and the sealing ring as well as the clutch (reinforced version) at the same time (yes, the gearbox had to come out of course, grrr). Now the engine is running better than before. Best regards from southern Germany
My 2012 GTI had surging idle just last weekend. I am pretty sure it had a highway speed (60mph) misfire for a month or so, engine check light came on Sunday,got it repaired and new valve fitted next day. 58,000 miles. Warranty covered full cost, running much better now.
Bro you're the MAN! Cant thank you enough! My 2011 has been in and out of 2 different shops 5 times and a total of 680$ later only to have to diagnose it myself...and it was the pcv valve! Seriously thank you again I can finally SHUT THIS WHISTLE OFF! My car literally sounds like a JETSONS car
Mine too! 😂 Not anymore
@Bonnor Bassidy mine doesn't either anymore...I traded for a vw golf wagon. Love it.
You are what a CZcamsr should be. Thanks for your help.
Thanx for the video . I have a golf mk5 1.4 tsi with 200 hp and i was thinking that the chain timing was of because it idle so weird. But the pcv valse was broken so that saved me al lot of work.
This series has been a life saver, thank you!
Hi there , what signs exactly you had on your engine ? Please i really need a help, thank you :)
@@uzzomuzzo1031 I haven't done much to mine yet, but I have oil leaks, engine noise, jerking when shifting gears, and more. But I actually posted this on the wrong video; I have a 2.5L MK5 Jetta (not a 2.0 engine like the one this video is for).
So far, all I've done is replace the gaskets on my vacuum pump to fix my oil leak. I just did it 2 days ago but so far I think the oil leak is fixed. For now, at least.
@@Espadazorz does changing this pcv can solve jerking when shifting gear?
@@kitsuvanphet8913 No, it doesn't. I've actually still neglected that issue. From what I've read online it's either because I'm low on transmission fluid, or one of the internal components in the transmission is cracked.
Excellent video and information. Mine just failed. Good thing I have a second vehicle while parts come in. Def a DIY part specially if you are a little bit mechanically inclined. Save the doh!
2012 GTi DSG just got Stratified Stage 2 tune now I got 2 code. Arm downpipe and Unitronic cold air intake. Been on cobb stage 2 for the longest while no problem until Stratified tune. P2187 and P050A
I was able to replace the PCV diaphram with Dorman part number 917-064. Cost $18.00 Pried out the old and snapped in the new diaphram. Easy and stopped the vacuum leak. 2011 Audi A5 60K miles.
Dude I have watch most of all your videos good luck to you and and yours stay in touch love you bro Volkswagen yeah!!!!!!!!!!
WOW!! I need to thank you so much for this video, it saved my ass. I had NO clue why my 09 Jetta Wolfsburg was screaming at me (squealing so loud), I assumed a pulley or something belt related, never heard such a consistent squealing before. We than got a bunch of misfire error codes and P0507 which lead us to you. The car has been misfiring for over a year and no dealership or shop has been able to figure out why, I kept following the symptoms and replacing coil packs. Finally a shop told me "MAYBE" it's a dirty fuel injector which is a bigger fix on the wolfsburg because you have to take apart the engine more than most other cars. Instead of going down that route we started running fuel injector cleaner at every fill up for months, it seemed to help but the car still had misfires while starting up. We were driving around and the car seemed to be driving fine than out of thin air started the loudest squeal ever, of course we were downtown and everyone was looking at us like we were idiots. Long story short the only way I was sure of the problem was by watching your video and I found the diaphragm under the pcv valve cap/cover was torn just like you said they do. The PCV valve was also very built up with hydrocarbons and oil but I cleaned it out nicely. Now I'm looking for a replacement for the cap and diaphragm. I followed forums and people are recommending the "Dorman 917-064 PCV Diaphragm Repair Kit for Volkswagen" which you can get on amazon for less than $20. Hopefully that will come soon, car is out of service until than.
Okinawapajero Glad the video helped!!! Would you let me know what you think of that repair kit? Those valves are pricey, I would love to test another solution.
I put my finger over the weep hole and the pitch of the whistling changed. Any pressure applied to the cover the PCV caused the car to nearly stall. Bought the PCV, swapped it out. All is good. 45 minute job start to finish. Thank you for the great video, it saved me some $
+Matthew Klueppel heck yeah!! So glad I be able to help
Hi, I have just replaced mine due to smoke and a little gudder at idle, my new 1 seems to have a very strong vacuum via oil cap, also there is a slight whilst at diaphram and when I put my finger on the small hole it stops, does this sound right or have I been sold a new faulty part...
You save me money. Thank you.
Thanks for posting this.
Got a "system lean at idle" code yesterday in my wife's 2013 tiguan. I suspected a vacuum leak. On inspection I took the engine cover off. I found that hole on the side of the PCV valve to be sucking in a bunch of air like you mentioned. I'll try the Diaphragm repair kit and see how it goes. Thanks!
yup that was it! easiest fix ever. Autozone had the $30 diaphragm kit in stock. easiest fix ive had in a while
Hey man keep up the good work!!
I discovered your channel a month ago, and I'm hooked! I'm also a vw guy!
checkout my channel i love vw
Sometimes despite for view on their channel.... hahaha
Nice sign from my Town into the background. Greetings from Wolfsburg =)
you're a great teacher,thanks
Just bought an 07 eos w/105300 miles. Drove it a week and added 1 1/2 qts with 750 miles. Went to the dealer after google check. I think I'll just replace the pcv after watching your video. Thank you.
Thanks alot....Mr ZZTop Mechanic
Very helpful. Thank you
Awesome videos man!!, can you do a video on the trotle position sensor
I’m pretty sure I have
Have the whistling noise, losing boost along with a slight misfire. Replaced the diverter valve recently.
Thank you. With this video and the Deutsche replacement tutorial, I just successfully fixed my misfiring and vacuum leaking Audi A4.
Can you do a vid on the fuel pump control module ?? Thanks in advance buddy!
Also, had my first PCV fail at right around 20k. Has been replaced twice.
Just replaced mine! Idle feels so much better and low rpm’s a lot smoother.
good video I think I may have to change mines my car run great no signal lights are mis fires the only problem is my car burn alot of oil I have a 2012 vw eos tsi engine 84k it's like every 600 miles are so I had to add oil the round circle piece u had in your had I do see a lil moisture from there
Very informative video, quite precise. Thank you. Made me more confident to purchase and replace my own.
+Ryan Miller thanks!!!
A great video ! Is it please possible to switch the pcv valve to a oil catch can?
Tanks bro this is very good video tanks alot..!!!
Good ideal is to give us all the part number too, that will be a plus and big help
+Linh Tran I don't want to do that. Part numbers change all the time and have different applications.
It's a great idea for sure. I just don't want someone to get the wrong part.
Thanks for share
Great video! I had a Volvo V70 which caused main seal leak, with no codes when PCV went bad. $700 to repair, ouch! I have a 2009 Passat which should be a lot less expensive (if I get a code) and especially since I can replace myself. Have you done a rear main seal replacement video? Thanks.
Gracias bien hombre !
My 2015 Jetta started to go thru oil. Took it to my vw mechanic told me it was this unit that got "pissed" and crapped out. Had to replace the whole unit. Doesn't burn oil anymore. Love my car. Just very touchy.
Thanks for the video. Definitely looks like a DIY replacement.
I did however want to make sure I don't change mine unnecessarily. Would you always hear a whistling noise? Or for just some type failures? I suspect mine may be bad, but I don't hear a noise. I do have a leaking seal.
Can a bad PCV cause a car to stall? My 2008 Passat LUX (2.0 TSI) with 173,000 miles will run for a bout 15 to 20 minutes and then stall. Once stalled, it will only run for a few minutes at a time. Originally, it would not even crank until it sat for 45+ minutes. I have replaced the fuel filter (definitely needed it), and now it will crank almost immediately, but not run for long.
The feedback I've seen would indicate to next look at the Control Module for the in tank pump. Next would be the in tank pump and / or the high pressure pump. I did see someone mention that the PCV valve caused their passat to stall - not sure if that was unique or common.
Think I may change mine. Have some misfires dancing around cylinders. Already fixed a misfire once with new coil packs. Looked at this last night I see a bit of oil around the outside of the diaphragm. I don't think oil should be getting out of that.
hey thanks for all your videos. I was just wondering if a bad pcv would cause my 2008 tsi to bog down or stall if i remove the dip stick. I just replaced the rear main seal and the pcv valve 6 months ago.
Yupp. I'm replacing mine with a 034 plate and catch can on my A3 8p
bom dia chef so do brasil essa dica sua vai me ajudar bastante pois estou com uma vw tiguan 2011 e esta com esse assobio e tava me deixando louco otimo trabalho esse seu no youtube brigadao
It's possible make the engine run properly without the PCV or even the Valve Cover installed. You just need to Disconnect the MAF sensor and Start the engine.
First of all, you are a legend!
2. Is it possible to replace the only the rubber diaphram? mine is sucking a little amount of air so I suspect the rubber is starting to fail?
3. Is itpossible to open the valve on top and inspect the rubber diaphram without totally recking the part?
Good video I was wondering if it could cause a p0068 code many thanks
Thanks @HumbleMechaic but seriously VW make some weird parts lol.. I myself love how simple my system works.. valve cover, screw in PCV routed to catch can. On the other side of the can I have an Elite Engineering one way check valve (the good one) to keep any turbo pressure from bleeding back through the can and PCV.. It's just added insurance as I don't need the turbo popping the PCV apart and spilling it's guts into the valve train.
Love the show, lots of info!! Had my intake tube off the throttle body and noticed a lot of water pooled in the ribs. Could the PCV be failing causing that or is that something else?
2012 CC 2.0 TSI
Replace this before it fails. I have 2009 Tiguan with bad oil leak at 80K miles. Great video. Bad engine.
Thanks so much
Great video!
Just discovered that ours is failing on our 2010 CC. was going to have our mechanic do it but you're making me think I can do this.
+Andre Thompson It is a hand full of T30 torx and you have to remove the coils. no too bad. Be careful of the rear hose. It has a small nipple that likes to break.
+HumbleMechanic I'll let you know how it goes.
Where is the PCV valve located on a 2014 TDI 2.0 ? Thanks for any info thank you so much
You mentioned that one of these going bad can cause oil leaks in other areas like the main seal. Once corrected does this help with those leaks or once they start you need to address those as well?
Just did my timing chain in the tsi ( thanks fro the great vid @HumbleMechanic) ...0.04deg from 4.20! But I instantly got a idle lean bank 1 msg....Wondering I I screwed the PCB valve somehow.......
Is it true, that if you take off your intake to do a carbon cleaning, and the carbon build up is moist and oily, that's a sign of a bad PVC? Recently read this somewhere, but I can't it again.
Good vid,thx😊 my 1.8 tfsi runs great,no probs. If i lift the oil filler cap thete,s a minor vacuum. Is this good? Engine keeps running nicely without the oil filler cap. Thx again,good channel you got here 🎉
what causes the squeeling sound that seems to come from inside the timming chain covefr ?? my PCV diaphram is shot and am replacing it in the morning but that sound is no where near the bad part ... i thought it was the ideler bearing at first ... anywazz thanks your video solved my problem anyhow
great video. I have a p0301 code that re-occurs. changed coil packs, but code reappears. Also under heavy acceleration, the rpm's go nuts. rev high, rev low. then returns to normal. Any ideas?
Any hints about the front PVC on the VW B6 2.0 TSI?
Love your show.. I'm having a weird oveboost between 3-4k followed by misfires on a TSI + K04. Upper RPM range the car is perfect. I've checked all the hoses and no boostleak. Could the PCV be causing this.
Did you ever figure this out?
@@3abo0od96 yup. Map. Switched to the 3Bar beta file from apr and set
Would you recommend a pcv block off plate to avoid all these wear and tear problems. I have an Audi a4 2008 and I have a block off plate but know I have some oil in the turbo pipe near the bottom of engine
Many thanks Humble mechanic ,i just subscribed . Any one know what would happen if you delete diagram ie (strip out) ect , vent to atmosphere , and cap off intake of pipe on turbo elbow ? But i think that would be an MOT fail here in the UK .
would you recommend a catch can to help with this?
thanks and great video! Would a failing PCV on a 2.0 TSi cause oil consumption? I just had to add 2 quarts of oil in under 2k miles since my last oil change.
Hi
Did you solve the oil consumption problem?
Is there a downside (other than not being an OEM part) to replacing the PCV with a catch can kit?
you are the best.
Hello bin watching and taking note had pure problems with are mk6 golf gti £12000 worth and still got engine management light on 😡
Great Video? Do you know if there is much difference between this and the 1.4L TSI engine? I have a VW Golf V GT TSI 170. Which has a faulty PCV vavle however I cant seem to find a video on it.
I have a bad pcv valve is it good to had the oil catch can or I have to replace it too as well
I had a question I am hoping you can help me with. I have a 2010 Audi A4 with the TFSI engine. If my PCV is failing or going bad, how long could I safely drive? I would intend to replace it asap but unfortunately I am in a position where I wouldn't be able to immediately. Would going 100-200 miles be detrimental to the engine?
I generally HATE VW Products but if i had to work on it your DIY videos make it A LOT more tolerable. Good work, long live the beard !
Rock on!!! they are not too bad ones you get to know them.
I had the same problem . I taken mine to a mechanic paid for a new PVC after getting the car back I was getting those 2 codes . When I went back to the mechanic they had heaps of excuses even used Snap-On scan tool and couldn't find the problem they also believed it had to do with my stage 1 tune . After year later of no boost/lag/bad idle and bad gear response/ I went and checked the hose that runs from behind pvc to the intake the hose was cracked. After some glue and self adhesive tape. Now my Golf Response/boost and doesn't have any issues .
Wow glad ya got her fixed
What would cause the pcv valve to fail? Changed 2 so far in less than a month. Audi A4 b7 1.8t
thanks dude
I have had a reccuring p0171 on my passat b6 2.0 TFSI. Changed the PCV and break booster hose. Also changed sparkplugs and ignition coils, not because of this problem but because it was planned.
Still having problems with p0171, now worse than ever before. The engine is reving up by itself when in idle..
Any good ideas would be appreciated!
Hi, Smoke from exhaust on boost can cause of bad PVC ?
Can this cause low oil pressure?
+HumbleMechanic I am looking to DIY this on my 2010 GTI, per your recommendation. Any idea if the generic OEMs (e.g. Vaico) are as good as the genuine VW part for this PCV valve (06H-103-495-AC)? Thanks so much - your videos are excellent!
can explain about parking break mechanism in dsg7 gear box with cable connection
I actually have a engine code for p0068-map/maf throttle position correlation and I change the map and maf sensor but still have it so I’m guessing the PCV valve is causing it as well because the OBD scanner says it could be a vacuum leak from the intake manifold
Do oil leak from the rear breather hose and into the air intake pipe is also due to a bad PCV valve?
Hi Humble
I have a bad PCV Valve on my MK6. What is your recommendation replacement the Valve or put a catch can kit and eliminate the OEM PCV Valve..???
Thank you.
What vacuum reading should i get if i put a vac gauge in the oil dipstick tube?
The reason why im asking is because i put a new pcv on my car but there is sooo much suction. When i remove the oil cap there is alot of vaccum. You can even hear the suction from the air box.
