As an A4 B8 owner, I just wanted to say thank you! Your videos have been incredibly helpful for troubleshooting issues with my car and are saving me hundreds of dollars I’d otherwise spend at the mechanic.

[@criswetzonX]

Thank you man!! I wasted $700 to get my car fix and no mechanic knew about Audis like you! They change a lot of things and now that i saw your video I fixed it myself!! Thank You!! The Best 🔥🔥🔥🙏🏼💪🏼

hey man so fixed mines bro ! i ordered oem Audi coil packs make sure they're the right length the first set was a millimeter off idk if that changes the reliability, but also change the spark plugs as well as fresh oil and filter, and i new MAF sensor and that'll fix your problem! i thought it was my PCV but no i was wrong ! the parts came out to be $530 and the tools costed $240 so in my opinion its worth doing your self took me about 2 hrs for all of it ! best of luck to you man!

Thanks for the video. My 2009 A3 TFSI 2.0 has 90,000 miles on it and I noticed the same issue with the oil fill cap being pulled by vacuum back into the engine. I replaced the PCV breather and found that the old one didn't pass the pressure blow test. The diaphragm was also torn in three places. This was an easy fix thanks to your explanation. I'm building up confidence to replace my timing chain and tensioner myself.

I just paid $1202 for my local dealer to perform this fix on my 2010 A5 that has already had the full rebuild for oil consumption. Drat. I could hear it whistling on acceleration at ~2300 rpm and thought it was turbo leak. Engine light came on with my wife driving and car started running rough and lurching. Took it to the dealer. Fixed, but your video is 8 minutes and they charged: $787 in labor, $258 in parts, $60 for oil & filter.

have you had a vacuum pump leak? If you have Id love to talk to you more about it because Im a little confused on mine.

[@ivancisneros6383]

Same! I have the same car with the same issue and I can’t figure out what’s wrong

[@djmatt1]

I was getting the dreaded 'Low Oil Pressure, Switch Engine Off Immediately' warning on my dash (2010 A5 2.0T) and that freaked me right out, I managed to limp the car home (about half mile) shutting off the engine every time the warning came on (only happened at or around idle), saw some of your videos and some other mechanic's videos after noticing how difficult it was to take the oil fill cap off while engine was running (I thought that wasn't right, should be way easier) so I ordered a replacement PCV diaphragm incase I broke it when I removed it to check, sure enough there was a half inch tear in the diaphragm, replaced the cap with a new one, no more extreme vacuum in the crankcase, let the engine run for a half hour, got up to temp, made a short run out, no warning on the dash, engine sounds normal. I ordered some low and high oil pressure switches just incase the warning comes back as I'm fairly confident it's not the actual oil pump, going to take it for a longer drive today... fingers crossed!

[@VoPo20]

Sounds very familiar. I have that same alarm pop up every 2 years (I have the car 6 years now), each time I need to replace the pcv and it is good to go again until the pcv fails again exactly 2 years in (give or take a month).

[@zeroxthree568]

did that fix it for you ??

[@christopherlaw2460]

I have the diaphragm for a good 4 months and now I’m just getting around to fixing it, along with the spark plugs and coils. Very good information about this, I knew I could do it but today I will complete it

[@liviofazi4017]

Some person had got rid of the pcv . His contention was that it allowed soot to build up in the manifold. More importantly he said it did absolutely nothing for the vehicle. He had setup some kind of collection system and had blanked the pcv right out of the equation. Can't remember the forum, but worth a look.

[@SavardAdam]

Love the content man... glad I found your channel. Just bought a 15 A4 allroad.... this video just helped me replace the PCV valve!

[@angelofrancis9014]

@naptowntuner your correct about the pcv creating vaccume. I learned that lesson this weekend when I reassembled the fuel injectors along with intake breather and "the whole shebang". I was having a misfire on cylinder 2 and a random on cylinder 4. I almost believe this was all cause by a vaccume leak. That nipple on the intake under your index finger where you removed the hose for pvc. If you had blocked that it would have run perfect. When the pcv fails that nipple can be blocked off to create vaccume.

Ooo hey I got my name mentioned haha. After I put my k04 Turbo on and I was data logging with IE it blew that hose off during hard pulls. My car ran terrible and I thought I blew my motor. I got home and saw that hose was blew off and was so relieved. I am very new to these cars so I thought my motor was done. I zip tied my hoses on so that wouldnt happen again. Only had it since March I think. 3 weeks after I bought the car I noticed it burned a quart of oil every 300 miles and it started to smoke real bad. I wish I did research and knew these cars had that issue. I had to remove the motor and replace the pistons and rings.

I just replaced the PCV valve with the original one (Mann-Hummel brand), I am waiting for your solution suggestions God bless your hands!

[@betawizard]

Great video! Any advice for this situation for my 2011 A4 Avant? I’m getting all sorts of error codes including the P1287 -System too lean at idle. The 1st mechanic said it was the GIAC ECM flash tuning I had done. The 2nd mechanic (who did the tuning years ago) said it’s not the tuning. The 2nd mechanic thinks it’s an vacuum leak. 1st mechanic found a lot of error codes mentioning misfires, cylinders, air leak. I even have error messages about the parking brake and the ABS system popping up on my display panel. My check engine light is on (not flashing) and it’s running a bit better. Before the idle was way off going up and down and it sounded like it was going to die. All the research I did thought it was the PCV/oil separator but I had that replaced a year ago and if you can pull the oil cap off easily while it’s running then it’s not the oil separator. 1st mechanic replaced the spark plugs last week. The coils were replaced a year ago as well. Next step is to take it to the dealer to do a full diagnosis. Any suggestions?

[@betawizard]

@@paulgarcia6257 Sorry for the late reply. It was the crumbled ITG air filter that was causing the issues. The dealer vacuumed it out and the tuning shop replaced the filter saying they were bad that year. So I only had to pay the $160 dealer diagnostic fee. Whew!!!

Amazing. This just happened to my 2016 Audi A4 but unfortunately, I didn't have a CEL scanner in order to diagnose it. Luckily, my mechanic is legit a great guy and is currently repairing this.

Need some help brother I got a 2013 A4 b8, During a cold start noticed car shake a bit then engine light popped up and the code read bad PCV oil separator, so replaced it with oem pcv oil seperator and engine light went away. It ran normal for a few months. Now the same engine light code popped up again, now I replaced another new Oil separator PCV because I suspected faulty part. Engine light went away and ran for 2 weeks with no engine light. The engine light is back with bad PCV code, I now suspect something else in the emissions causing the PCV to fail? My a4 does consume alot of oil but I thought that was due to bad pcv. I wonder if my cylinders are dirty causing too much crackcase pressure, now sure how to fix this.

Bought one of these cars recently and keep finding my way back to your videos! Great content! Would you know what the cause is for the PCV to suck up oil? I have the black top on it so bought another black top but when I took off the old unit it had quite a bit of oil pooling in the outlet to the turbo and in the outlet to the intake. Since replacing the new one seems to be doing the same. So I don't think the PCV is at fault... Cheers

[@eeemuse]

The black top or the semi-transparent are just different revisions of the same exact thing. This valve takes out the extra (hot) air from the engine and send it back into the intake system. This hot air transfer with it a bit of oil over the time. the diaphragm over the time between getting hot and cold repeatedly wears down and the only solution is to change the whole valve. There are other solutions such as modifying it by installing a catch can but you'll have to clean the can regularly.

Vcds showing lean codes etc..few injector codes. When I start it car idles fine for moment then tries to stall off I don't keep my foot on gas pedal to give it enough gas at 1k rpm, if let go it stalls out. Have to maintain just above 1k rpm to not stall out out. Any suggestions greatly appreciated 🙂 thx.
