Audi S4 B8 & B8.5 3.0t - PCV / Air Oil Separator Replacement DIY (Audi A7, S4, S5, & SQ5)

[@GetF0RC3D]

Just finished this job. Customer had coolant leaking in their driveway, topping up overflow every day or two.. Pressure tested at the shop and thought it was just the waterpump. Ripped it out but wasnt sold on that being the problem. Did some research and found your guys video guides on this job. A few people chimed in and said I ought to be checking out the t-stat and pcv while im doing that waterpump. Ripped the supercharger off and sure enough an odd 20mm pool of coolant sitting in the valley. My customer wasnt in a rush for the car back and it was a quiet enough day so I was able to take my time. Coolant ports on the pcv were destroyed. Its my first time doing a job like this on Audi and I was pleasantly suprised. Overwhelming at first for sure, but I dont believe things are over engineered, in fact pretty simple. Sure not a rip shit and bust kind of job. But if you take your time, any junior tech can do this job. Kudos to your guys channel for doing your best to guide people like myself through these jobs. Gave me total confidence for doing this job. Would not recommend buying an audi unless you plan on doing the work yourself, otherwise youll be billed a hefty bill in just the labor

When reinstalling your lower intakes, hold the flaps partly open or they will be stick shut and give codes . And after they are seated, actuate the flaps and make sure they move freely

[@ace7912]

They kinda gloss over the part at 15:22 where you pull the coolant pipe but it had me stuck for a while. There's two screws on the bracket in the back. The lower one is kind of unreachable but don't mess with that one. Just push the pipe out of the bracket sideways and then push it back and it comes right out :)

[@aeda84]

Not seeing that bracket but what im reading from others is that pipe is connected to a flexible brakcet/pipe and can be pushed back. Is that accurate ? I think ive spent more time on this pipe than replacing the waterpump and thermostat.

[@ace7912]

@@aeda84 yeah same that part sucked. It is connected to a flexible piece so you just take the one screw out and slide it out towards the driver side

[@apopkajamband3224]

On mine someone previously replaced the torx with a hex screw. The bracket is bent back enough to get the screw in without going through the bracket. It just runs right through the pipe. A ratcheting box wrench made quick work of it. Really good hack imo.

[@ijdad99]

I've spent an hour trying to get the pipe out. I could remove the T30 at the back just using a T30 on a 5 inch extension. But that pipe just won't come out of the hole up at the front by the thermostat. If anyone has a suggestion, please put it here. Thx.

If it's like the 3.2, not only do you have to hold the flaps open a bit, but after placing the manifold back on you need to hold the manifold down while tightening some screws. Once screwed down, ensure the flaps move manually before final torquing.

Love your 3.0t series of videos, very good instructions and detail. My PCV went bad and my symptoms were high vacuum on oil cap while running, leaking seals, and rough idle. all of those went away after pcv replacement. It's a good idea to do all of these maintenance parts at once because they are all under the supercharger.

[@r8risk]

Ideally you should recommend before doing this job to remove the fuse for the fuel pump and start the car and let it die or let it crank for a little while longer. That way the fuel lines can have it's pressure reduced from the dangerous high pressure it might be primed at. Then you won't have the issue of the line being primed by opening the door.

[@mosinnagant76]

I saw this comment and followed your advice. Still leaked some fuel when pulling off the manifolds and the fuel lines but didn't seem to be as much fuel as in this video

[@r8risk]

@@mosinnagant76 yes should be drastically reduced, a shop towerl around to soak up the residual fuel is also wise. Further, as you're backing off the fuel lines, back it off slowly so the higher pressure can slowly dissipate vs being flung out everywhere causing vapour and possibility of ignition of fuel.

[@Infantryman662]

Last comment haha maybe. I recommend replacing the gasket (ELRING 236060) that connects the oil filter canister to the engine when you do the PCV. Mine was leaking a LOT of oil. But buckle up its annoying to do.

[@BuyYourBuild]

Great vid! Maybe pull the fuel pump fuse B3 to avoid the priming issue mentioned at 9:30

[@gmr19]

Really great tutorial but have a few complaints (maybe the B8.5 is different). There is one more electrical plug below the MAF sensor and two more vacuum lines attached to that plug. I spent 45 minutes wondering why the supercharger would not lift off!!!

[@richmondvand147]

So some advice and explanations ideally someone will pin this: 1. buy some sythetic grease (permatex) for gasket lube, buy the narrowest bit holder you can for a t30, buy 6 or at least 3 injector gasket sets (with green plastic stopper, mine were brittle af) and o-ring yes theyre 50 bucks - but you own a high end worth it sports car its okay. Also make sure you have a torque wrench that goes down to 9 ft/lbs or your regional equivalent, a really good set of hose picks (vim are good) and a nice small to large assortment of pry bars (mine are the 3 set from Craftsman) 2. If you have a stock airbox then you may have to remove the "snorkle" between the air box and front trim using the 2 body trim clips then take that plastic piece out so you can take the belt off (it makes room for your long wrench). Dont do what I did and pry the wide plastic part off -.- which broke them. you can reach under them from the sides and pop the middle up and out releasing the wide trim bits. Off to my guys for 2 trim bits. 3. dont try and pull the tab on the position sensor just use 2 picks and pull the 3 parts of the tab off the connector so it can slip off dont bother with the grey locking tab, slide your pick between the plug and the 2 black and 1 grey tabs then move them away from the connector while pushing down on the head of the connectors lip - wont break the grey tab like i did but came right off (this works brilliantly for both flapper bodies). Also for those grey tab pull and pinch connectors, sometimes they just get stuck so I wedge a pick tip between the body of the connector and the bottom of the grey tab on the front of the connector which is usually enough to unstick it. 4. Also those flapper assemblies are hard as fuck to get off just disconnect like he did here and pull up and wiggle, lots of wiggling I also GENTLY pried on it after much sweat tears and swearing pried from the valve cover side like barely and in mulitple spots - always be wiggling. 5. vaccum your intake and then cover and keep covered as often as possible 6. you can just remove the air hoses that are attached to the PCV unit from the heads really easily so you can reduce the chance of breakage 7. For that FUCKING coolant pipe (lol, it is a good design though once on wont come out) over the Valve body make a thin metal shim, twist the pipe to slip the shim between the moulded bolt hole and connector bracket then with a towel around the pipe near the block side gently put a pair of pliers either vice or regular (no needle nose) around the bend down and with a pry bar braced against the metal block at an angle pry against the pliers - this should be enough to pop off the coolant pipe so that you can manually push it back (basically like cracking any bolt, once the hard bit is done you can do it manually). 8. When inserting the flapper valve back on make sure the gaskets are lubed with syn grease (permatex is fine) and make sure they're on the nozzles to your injectors otherwise you'll have a bad time. Ideally you'd take other flapper body off and replace those gaskets as well as the passenger side sure they're 50 bucks a piece but piece of mind right. Also he quickly mentions it but it needs repeating MAKE SURE YOUR FLAPS ARE FULLY OPEN WHEN PUSHING THE BODY DOWN and that when the flapper body is down that you can see the metal baffle in each intake that the flap rests against. if unsure try actuating the flaps if they do not go down then you have inserted incorrectly and you'll throw codes along with power issues. 9. If you have a fuel leak after testing by opening the door it will not do it again (or at least mine didn't) I talked to my shop and disconnecting and reconnecting the batter MIGHT work but as a VAG auto owner I have a rosstech aka VCDS so just went into the engine module and hunted around looking for a fuel pump test or in my case a "fuel pump electronics test" you turn it on and it primes continously so make sure you stay close to turn it off because you have to turn it off manually in VCDS 10. lube your air intake gaskets lightly 11. make sure that your double ended vaccume hose the U shaped one is up and to the side so it can come around the back of the super charger 12. I found it really easy to do the coolant hoses when the bracket at the front was attached so kinda get the ones on the super charger aligned then put the bolt through the bracket and align it with the bolt then tighten - easy peasy that way. 13. def use a vaccume bleeder for the coolant super easy and you can check for leaks. Schwaben @ ECSTUNING makes a decent one for 75ish USD that works with an air compressor or hand pump 14. when doing the belt grab a pry bar or two (I have a 3 set of craftsman that are perfect). Use one to put light tension on the loose end by running through it across the rad and block (its not tight just keeps it from dangling so you can use the longer one to nudge the belt back onto pulleys (worked seamlessly). Then use the short one to hold the belt if you dont have a long ratcheting wrench (i didn't) so I held the belt it its barely on position using that pry bar and repositioned the wrench on the tensioner to get the needed amount of slack to gently use the wide pry bar end to work the edges over the pulley - worked really well. 15. before starting make sure to recant the litany to the Omnissiah and offer praise to it's machine spirit (if you know you know haha)

[@cesarcasas9111]

I've heard PCV is also named Oil Separator, finding coolant in oil is it also a symptom of a bad PCV? Your videos are awesome, thanks

[@The3lloba]

I don't think that's always the case. PCV valve returns the oil vapor or particles from the crank case back to the intake manifold. Oil mixing with coolant might be the oil cooler seal. Usually the oil cooler sits next to the oil filter. The transmission also has one to cool ita fluid down. Those oil coolers have seals to prevent coolant from mixing with the oil. Check them out first before PCV

[@balepa.balepa7172]

Check your intercoolers inside the compressor. They can have coolant leaking

Doing this for the second time this year. The PCV valve seems to have failed. Ugh. This time I bought the special 16mm tensioner tool from Harbor Freight for $20. Took no time at all, and I have an my knuckle skin. The first time took over 30 minutes, and my arms were all hacked up and most knuckle skin was gone. Definitely worth the twenty bucks. I do wish there was more filming of the tubes around the "neck" end of the PCV valve at the firewall end of the PCV valve. I think I may have incorrectly put a line under it that should have gone over it. I'll know soon enough. That was the only trouble area during attempt number one, other than the tensioner tool.

Same process for a 2011 3.2 q5. I had to remove an intake runner as well. Very easy!

[@ijdad99]

Ok last comment. :). To answer the question about the risk of coolant in the engine... If you drain the coolant as in the video, very little coolant should be remaining once you remove the PCV valve. The cavity in the engine that the PCV valve occupies is fed with oil from the oil filter side of the engine through a hole about a half inch from the bottom of the cavity. It drains through a hole at the engine front side of the cavity through a hole at the bottom of the cavity. The coolant holes are near the oil inlet, so if excess coolant drips into the cavity, it'll get caught in the bottom of that cavity. The bottom isn't flat, but has a small dam that will make a catch area. It'll be filled with oil when you pull the PCV valve out. If coolant is in that catch area, it can be removed with shop towels. No coolant should get in the engine if care is taken. If a dealer days it's required, they're either gouging you or reckless. Probably both. However I will say that I took the time to remove the intake on the driver's side of the engine. If that is done, the access to the PCV valve is completely clear and the PCV valve can be removed perfectly level. I didn't want to crack any vacuum lines, so I used this method instead of the yank-the-guts method in the video. But I'm an amateur and I'd probably wreck something if I tried the video method. For sure no coolant dripped since it was level during removal. This is such an amazing video. Thanks so much for providing it. Your company rocks.

[@kylemazur1447]

[@ijdad99]

If FCP is still reading these posts, I have a question. I replaced the PCV valve at the start of 2022 due to coolant leaking into the engine valley (not from water pump or thermostat which I had replaced earlier). By the end of 2022, I checked the suction of the oil filler cap due to code P052E00 and the suction was very high. I returned the part in warranty and replaced it to find no difference. Doing some research, I found that I should have also replaced the crankcase breather hose. So I then replaced that. I also replaced the connector pipe between the supercharger and the PCV valve as well as the gaskets between the supercharger and the intake guide valve housing. It's still throwing that code. I thought that these were the only parts causing that code. If I hook a clamp up to the oil filler cap and attach a luggage scale, it shows about 5 pounds force to break it free, which I read is on the high side. Does something have to get coded at the dealer for a new PCV valve? I thought it was all strictly mechanical. One other question... at 4:17 in the video you mention removing the connector to the Hose Evap. Well mine were on really tightly due to that hose degrading over time so I removed it at the little black canister that the house connects to. Unfortunately I broke the end off of it. I taped it all up and it drove but I'd like to replace it but strangely Audi doesn't show that part in their schematics. Do you know what part that is and does FCP sell it and or the hose itself? Is it hollow or did something maybe fall out when I broke it? Like if it's a check valve. Thx. BTW, this video is great. I can now do this job practically blindfolded.

[@showmx1]

Thank you for the video, the FCP videos are the best! I didn't hear any mention of replacing the crankcase breather hose while in there. Had a shop do the PCV job, and months later the car is throwing Error Code 20136 - PCV Valve Malfunction in VCDS although there is no check engine light on. The little research I've done seems to point towards the crankcase breather hose, meaning it all has to be disassembled again. Any insight on this? Thanks!

[@fabiogutierrez2537]

Loved the explanation. I just changed the crankcase valve on my 2017 Audi Q7 3.0t. After starting up the engine lite came on and a P2014 code came up. Any recommendations? Thanks

[@ijdad99]

I know this is really late, but for anyone reading later... This is the standard code saying that the intake vanes under the intake manifold are not moving when told to. If you removed the intakes (like if doing carbon removal) then when you reinstalled them they got caught and won't move. But if you followed the video and didn't remove them, then my guess is maybe you missed attaching the vacuum hose to one side or the other. Those vanes are moved by little vacuum powered motors. On the plus side, if that happened then they should be ready to see and reinstall without taking anything off.

[@mk_ultrarunner]

Wow! This looks super involved. All those electrical components to undo, hoses and lines. This looks outside my comfort zone, but would cost over $2,000 at a dealer or even import garage. How long did this actually take in real time? Also have to vacuum/bleed the coolant looks to be an issue without the proper tools. I also read you have to get the ECM reprogrammed due to the lower pressure after a PCV Body is replaced. Is this true? if so, that's like an another $200 dollars. Is this also for the Q5 3.0T?

[@Hopelessthugg]

Slight vacuum is normal. If it’s stuck on so hard that you have to use force to remove it then it’s probably bad

[@302hobronco]

Thank you. Doing this on my 2015 q7. I need to check out more of your videos. You have one on an intake cleaner to remove carbon build up on back of valves??

[@mrmixxy]

why did you remove fuel injector manifold?

[@adamsalwasser7008]

4 hours to change out oil separator, 4 days and counting to get the fuel rails to stop leaking. Bought o rings - still leaking. VERY frustrating. Had supercharger off and on at least a dozen times. 2015 A8. 3.0t. I’m missing something , but I can’t see what.

[@MrDevp1983]

Is it necessary to drain the coolant from the bottom (min 8:10)? Can we skip this step?

[@ijdad99]

Definitely drain the coolant or when you discontent the supercharger lines, all the coolant in the supercharger will pour so over your garage floor. And you want it out of the PCV valve area or it'll drain into the engine, which is open when you remove the PCV valve. Think power unit in Iron Man's chest.

[@JDJD-mw9rr]

How much oil cap vaccum is too much? I have some, it will hold and pull the cap down but its not crazy strong. How much is too much, shouldnt there be some?

[@gregoryfairchild2460]

Having high oil consumption like 2 quarts between changes. Oil air separator the cause? Not leaking anywhere 167,000 miles runs flawless

[@gregoryfairchild2460]

Oh...2012 Q7 3.0t

Your da bomb doing this on my moms SQ5 should be the same right?

[@fcpeuro]

Same process, good luck!!

[@AutotechHuncho]

Just hit 86k on my sq5 and the the light came on. Plugged in my scan tool and shed a tear 😢

Thinking of you 💜

[@NIKARTIST89]

Is it possible to replace directly the pcv valve and didnt touch original oil separator?

[@misbehaving3469]

Will a bad pcv unit cause coolant to mix with oil

[@jayboom10]

That T30 to get that coolant pipe out is a pain!!! And that's an understatement.

[@reubenl6189]

I ended up cracking the secondary air pipe trying to unscrew that t30, hardest part of the whole job!

[@daviddebuhr8995]

Get a small ratchet bit driver. Takes it right out in that tight space.

[@Mighty_Maatie]

Great video! I've been waiting for this one.

[@manalive33]

Excellent video tutorial.

[@gavanphotography7814]

Why do you have to undo the two coolant lines underneath the car? Is that not counterintuitive?

[@18wolf7100]

How did you get that coolant return pipe off? I am stuck here....

[@StevenDamboise]

Excellent video!!! Thanks very much. Can the fuel rail line be reused or does it have to be replaced? Any issues with leaks if it is reused?

[@richmondvand147]

the fuel rail is built into the "flapper body" so yes you should reuse it unless you broke it or is damaged prior. I would give you the advice as a VW enthusiast gave to me: turn the flapper over and make sure your gaskets aren't stuck in the ports because they most likely are. 2nd probably should replace the injector o-rings and plastic brace (green bit in the injector seal kit) 3rd is get some permatex synthetic lube and lube the o-ring making sure its on the injector under the lip

[@ivanstory6986]

I am having real trouble getting the intake manifold off, i believe its the injector seals which are preventing it coming up. Is there safe way to pry it up? Also, i forgot to order injector o-rings, are they vital to be replaced? Is there a size I could use from a local source? Thanks all

[@garethwood4316]

I can see this question has been asked many times. I’m stuck on this too, Audi S4 B8. Were u able to solve this?

[@ivanstory6986]

@@garethwood4316 yeah i ended up just forcing it off. I think i lightly levered it with a screwdriver (using a rag to prevent scratching) and then just man-handled it off. its caused by insufficient lube on the injector seals and so make sure you put something on them before reinstalling.

[@ivanstory6986]

oh and i reused the seals. I just checked them carefully for any damage and i think i flipped them over as one side does more work.

[@mikelikesbeer6090]

Having the same difficulties lol, about to try and gently pry it.

Fuel leak on the regulator or one of the lines most likely

[@malcolmjohnson4977]

@@andrewroyal8855 yeah I when putting everything back I put the fuel hose under the air intake and the engine burned it

[@elmoti]

I have a loud noise on my 2012 A6 Quattro and thought it was the PCV valve. I called the dealer to buy the part and they said that my car does not have a PCV valve. I am confused.

[@tb3780]

Anyone seen a video to do this for a C7.5 facelift A7? I've got the supercharger off but there's a lot different given dual port config etc... only finding pre-facelift vids.

[@Wrenching4Everyone]

Is there a part number for the cold air intake on this vehicle? I realize it's an older vid, but figured I'd ask.

[@Jorgetrader]

Fucking awesome job and crystal clear explanation, dude is a pure craftsman.

Is important to leave flaps open or closed before installing tumble housing ?

[@fcamtero]

When I installed the tumble housing I don't remember if it was open or closed. I started the car(2015 q7 v6 ) everything seemed to be fine until I connected my obdscaner p2006 came on intake manifold runner control stuck bank 1 .if it is stuck how do I solve this problem. Does it affect the performance of the car?

Can a bad pcv cause an oil leak that is significant or possibly the oil valley pan maybe cracked? Have a leak but seems like it coming from inside engine but cant tell where. Was told it could be one of these 2 parts.

[@plutodestroyer12]

hello friend - I have a 2010 s4 full apr catalogue . I just hit 70k miles and today i started the car and the start up was rough as well as the idle until it got warm. at a stop sign there was a bad smell and a very light amount of grey smoke coming from the exhaust. any ideas? no cel and car didnt overheat.

[@rival3825]

Nice job bro. Do you have to have a gasket underneath?
