- Replacing the bad PCV on my 2011 Audi A4, because it was running Rough at idle. Also throwing a fault code for bank 1 running too lean at idle. When I replaced the bad PCV valve the car ran like new.
Great tutorial! Worked perfectly for my 2011 a4 b8 just under 70k miles. Took out the rough idle and audible whine from the engine. So far, no repeat on the codes.
The video doesn't mention it, but put the breather hose back on.
Thank you for this. Never done this before but this video let me do it in less than an hour. Fixed my misfire and low idle RPM fault codes too.
Worked exactly as described in video on my son's 2015 Audi A4 Quattro.
Did your car have a check engine light on?, apparently the symptoms of a bad PCV valve is that you turn on the car, and then try to remove the oil cap with the engine running, if the oil cap is easy to remove it’s good, if the cap is very hard to remove it’s bad, or when you take off the oil cap has a suction sound like a vacuum then is bad, mine has both of the symptoms and the weird thing is that I don’t have a check engine light on
@@B8_ghostt I hope you replaced or found your leak, you can blow a rear main seal if you drive around with a bad PCV and that costs more than 1K. Shouldnt have a vacuum.
please post more of such videos! I have the same model audi and it’s difficult to find videos for this year vehicles! cheers!
I need to replace mine too and they Charging me a lot of money your video was a lot of help thank you!
Do not torque/ over tighten the screws or you will strip them. Just tighten them snug.
JUST FYI u don't need to remove the entire part just replace the oil separator gasket and voila is done. The gasket will just cost about 40 compare to the entire part which will run around 200. Remove the circular cover that u see on top of the part and replace the gasket, it will come with the spring as well.
I just did exactly this. The circular cap has a built in gasket of sorts. Mine was all warped and eroded. Put the new $40 cap on and now it's perfect!
Smart.......afterall...nothing is wrong with the "plastic housing"
Just changed the big cap that all ??
The cap on top off the part
@@timidtornado2869Wrong, there is a one way check valve that sometimes goes bad.
THANK YOU MISTER saved me $$$ and it was so easy and fast it worked great video thanks
Do HAVE TO clear the codes with a Diagnostic tool. Or will it clear on it's own?
Apart from it leaking, what are other symptoms of a bad PCV? Can it cause vibrations at idle into the cabin when in drive and reverse gear.
Thanks for the vid man! Just changed mine
The replacement pcv you put on is the old style and incorrect part #, visually you can tell because it's all black. The updated pcv's have a translucent section on top, as the one you removed has. The old style one will lower crankcase vacuum and could damage the rear crankshaft oil seal as the ecm has been reflashed for the updated pcv you just removed and crankcase vacuum will be incorrect, also it will increase oil consumption.
I just purchased this part genuine Audi by VIN number and the part provided is all black.
The part you are referring to is specific to the 2013 model year and newer
Lance Fulfer the all black one is pre oil consumption update. Etka the Audi parts catalog does not supersede to the new style for some reason. I've been a tech at an Audi dealer for over 10 years.
steve- i have an 09 A4 with about 60k miles...i had the oil consump issue and it was fixed per audi recall, which included replacing pcv...6 months later, i have a RMS leak and my indie tech believes ita due to bad pcv. My Q is: could the pre-fix pcv caused my rms to leak, and since it was so soon after i got new pcv, should audi be covering my rms fix? thanks for you help!
steve - so, based on your knowledge, I should have a translucent unit in my car post- oil fix? if i have an all black unit, it can still fail and cause oil issues...ie extra pressure to make my seals leak? i will investigate further and see if Audi is responsible for the RMS leaking....TBC
Hi. Thanks for the video. Can pcv valve fault show "oil pressure low" on dash? Because my audi is showing low oil pressure fault & local dealer has tried everything.. From checking sensors to replacing oil & oil filters etc but that fault keeps coming on & off. Because of this the car is running on idle mode I think. Grateful to help out guys.. Thanks
Hi have same issues did you solve problems.
Fixed the problem 💯 percent!!!!!!!
Glad you liked the video, and it fixed your car.
Is this what causes oil consumption?
@@chriswolford7221 to my understanding yes
do you have to reset code for check engine light after? Or does it just go away?
my car sometimes shuts off when i want to accelerate it happened a few times. when I want to pull up it seems like it drops a little.
Its only wen i try to pull up.
No light at the moment on the dashboard.
Car mile 160.000 km.
Did your car did the same?
How does it sound when pcv valve have failure?
thanks for uploading this. How is the car running with it so far? Any problem with this part? Was it the correct part even though it's not translucent? I have an 09 B8 that i'll need to change pcv valve for as well, not sure which part to order as there are many to choose from on ECS.
Thanks
did u ever figure it out
Did it fix the ticking or what
Hallo 🙋🏻♂️
Problem habe ich! Am Audi A4 B8 2009 Benzin ⛽️. Öl und Ölfilter und Ölstandssensor und Öldruckschalter wurden getauscht! Aber Lampe immer noch an und schreibt noch ein wenig Öl ??? Wieso den
Aber es gibt auch etwas Seltsames! Wenn ich den Öleinfülldeckel öffne und wieder schließe geht die Öllampe aus!!! Es steht nicht, dass Öl im Motor fehlt
Man thanks a million!!!!! Because of your video I save my self a fucked up engine!!!! Thank again!!!!!!!
Hi,for 2.0tdi what is his name?
Still looked like it was idling low at the end of the video when you showed the clip
I have the engine oil reduce, and all the spark plug full dirty of hard carbons, is it bcz of the pcv ?
i have a 2012 Audi A4 Quattro when I start the car it hesitate to keep running at idle. Does this shows it needs to replace the PCV valve? Please advise thank you.
I would check if it is not misfiring first then go from there
Excellent.Bravo
anyone got a vid on doing the valve cover for this motor?? just bought one of these and never did a vavle cover on this motor before.
how do i know when to replace this?
I'm suspecting my pcv has also failed. I was told that to check it I have to pull the dipstick while idling . if the pcv is ok then the engine should idle roughly. in my case when I pull the dipstick there's no change in from at idle.
I'm getting error code p0172. system 1 bank too rich. If I drive with gheto catch can. I won't make and damage?
I was told that in some cases if pcv failes it might cause too much pressure in the engine and damage the rear engine seal. how is that exsesive engine presseure created ?
I don’t have a check engine light but I think my pvc has fault because when I pull the cap off the engine idles rougher
I can’t even pull my oil cap off, does that means the pvc is bad? I can remove the dipstick thingy and it idle rough. Also idle rough this morning. I have p2177 not 2187 though
Will a new one help with oil consumption? I have a 2015 model, and it seems like I have to change the oil every 1,500 miles. It's a stage 2
My 2014 A4 burning oil like crazy right now too. Thinking a new PCV valve might help since when I open the oil cap while the car is idling there is a lot of suction
Yes, it does help
Do you have oil on top off the engine ?? I having that issue
Jcniceberry that’s oil coming out the pub valve tube if u Liston closely u can hear the air coming out by the clip where it connects. Put ur finger around it to see if u hear the air stop leaking out n also u will notice the oil on ur finger from it being blown out.
@@therealspacemanyoutubechennal what's a pub valve?
What’s the black build up around the oil cap caused by? I’m getting that on my vw
O have the same thing.
Carbon
I tried replacing my pcv valve but now the car is misfiring. I put the old one back and its runs fine but the rpm is still high. Do after market pcv valves work on audi a4s? Mines a 2005 a4 quattro 2.0 T.
Carlos Flores do you have a solution for this I’m having the same issue
hitman415707 yea dont buy after market, i ended up going to the dealer and buying a official pcv valve from their and it worked
@@Los408 You probably bought the wrong one. I purchased my PCV from ECS Tuning, manufactured by Hamburg Tech and it worked just fine.
@@FamousSASkater ha im here now and just found a pcv valve from the same site crazy
My 2011 a4 is consuming oil. But I don’t have a check engine light on. I wanted to get a new pcv valve to see if that is the problem I hope to god it’s not the pistons.
Well, l didn’t have a check engine light either and it also burns oil. My car is an 2011 a4 as well, so I changed the pcv valve and it didn’t help. You might have better luck.
POLAK_213 I plan on selling the car I want an Lexus IS 2014- I’m tried of german cars. Want to go back to Japanese never has an issue with them ever since I got my 2013 bmw 335 and this a4 granted this is the only issue with the Audi. I hope I can fix it because I love this car so much especially it being a 6 speed.
Yeah I here you on that, German cars are troublesome. Lexus IS are nice cars, Japanese cars are known for their reliability in their engines. Hope it fixes it for you, 6speeds are kind of rare.
POLAK_213 exactly this is why I want to keep my a4 especially with it being a 6 speed black on black. I love this car, hopefully this will fix it I know these cars had a recall on the oil issue.
@@HotSizzleTV_ If your car is consuming oil, and it's a B8 A4 then I can almost guarantee that you need new piston rings. That issue is super common on this engine for Audi A4's 2009-2011.
Hi wonder if anyone could help me. From cold the car tells me to stop the engine and check oil.
When it gets to normal temperature its then fine.
Also it seems to be burning petrol so fast.
Thanks
Check if you have the correct amount of oil in the car
For the petrol burning probably needs a full tune up
if you do a video put the torque spec /setting in it.
Please, remind me not to buy a German car. Too much hassle, maintenance, and complexity.
Sorry part is if this was a domestic, that vavle usually ends up under 10 things and around a corner anymore. Exotic cars are made to be more user friendly in maintanence.
Stopped watching after seeing how you were taking the coil pack connectors out... jesus..
Push connector inward, pull back the tab, release the connector.
Literally that simple..
themobbkillas you probably never had to deal with bad connectors, trust me those idiot engineers didn’t count for plastic melting together, I got lucky that I barely got mine off but if you look it up everyone’s shit gets stuck
@@V8dadmartin You legit just talked shit but don't have anything to back it up , he is going to fucking rip the tabs pushing like that , right technique , EVEN if it is stuck , push inwards connector and then pull back the tab using a screwdriver or hand , but its to push nicely , not just fucking jam a screwdriver in there ugga dooga style and then it comes out nicely. How many connectors did you remove? Gotta love youtube mechanics.
@@MegaZ202 Damn dude you dont gotta be fukin dick about it! 🤡
Does the light go away by itself after the fix?
GrayGhost No, you have to use vagcom or code reader to erase the code.
my car is not starting. Is there any reliable audi service centre who can fix my car.
Someone help me. I did exactly what he do on video and now my engine light flashing... idk what to do
Engine light flashing is generally a misfire, check your plugs and make sure you plugged them all back in tight
where did you get that bro? how much. tks
Very helpful. I need to buy it on my car. I got an audi and its giving me alot of problems. Never again buying this fuckin car. Next year toyota or honda
Thanks.
too many metal bolts. audi should use just 2 plastic clips instead. as a car manufacturer is not wise to waste money...... :)
never in my life have I heard a recommendation to use plastic clips lololol this is a wild comment
