High Idle and Check Engine Light in a 3.2L or 3.6L VR6 - (Passat, Cayenne, TT, and more)

[@GeordanDuncan-mw8km]

I just made this temporary catch can set up until mine is fixed I’ve booked it in I’m sure the techs will get a laugh at my handy skills

[@JohannBartz]

Hello! I removed the same intake manifold without removing the front but I had to remove the entire air filter, the high pressure pump and the injection system. I took the opportunity to check the injectors. I checked the PCV valve and it was ok. Before isolating the PCV valve I will try to restrict the air passage with some type of stopper with different holes to see if it solves the problem 🤦🏼‍♂️😅. Thanks for the video and congratulations from Brazil!

What’d you find out?

[@CARBON10]

If anyone is hesatent in doing this,. Dont be , it WORKS, so well obviously if you think about it, After being quoted $2500,00 to repair and 3 week wait for parts , i did this, two minutes, absolutely bloody brilliant, now i have a happy 2007 r32 golf thank you mate for posting your skills ,😊😎👍. My rocker cover has a hole (factory) above the crankcase vent pipe, which has a silicone type valve thing inside , thats what decomposed, $19-00 on eBay, better than $680-00 from vw, but then you need intake and cover gaskets, total cost on ebay $130-00 for all

[@ohiojayohio9643]

Does ur car still work from doing this

[@CARBON10]

@@ohiojayohio9643 Yep, just like original, it's just crankcase ventilation, all engines have slight pressure build up in the sump and area below pistons, there's always a pipe venting this back to the intake to be 're burned, the r32 has complicated this, so go back to the time proved system, which works, some guys route the pipe to a catch tin ,so you don't burn the oil that inevitably comes with the pressure out of the sump area,

Just happened to my 06 Passat VR6 and thanks to you was able to isolate the cause as soon as I saw your video! Thank you! Like and subscriber for life! May I ask for any help on the parts needed for the pipes fittings/ hose you made for the intake catch can? Diameter of hose? How has the catch can been working for you? Did you ever reroute? Many many thanks sir!

Also any tip on where you got the cap to plug the vacuum?

My audi a3 3.2 has something like oil in the back of the car, it's everywhere, but no blue smoke comes out, nor do I have any of the symptoms mentioned, what could it be?

[@alexdegroot11]

I changed the valve.. hell of a job. The noise is gone and its running normal until i take the oil cap off. Its sucks the oilcap vacuum, wtf do i need to do now?

[@CashedOutCars]

If the noise is gone and it runs like normal you should be in good shape. It is normal to pull a vacuum from the oil cap, since it’s another place for the engine to pull air in when it’s open

[@StayInCourage]

If you changed the Engine Valve Cover PCV Valve Diaphragm. Then it the issue is with the valve cover gaskets and or the intake gaskets.

[@detonater1348]

I just did it today, the hissing is gone and I capped the intake with my gf hair spray cap cover. I didn't route a tube and catch can so far, light smoke coming out of the pcv will route it to a catchcan tonight. My gas consumption was so bad before this like 12-16 mpg max.

How fast does the catch can fill up with oil?

[@simonm8586]

Whilst the symptoms you mention are correct. Your fix, is shocking as it doesn't separate the oil & air, and draw in the vapours into the engine for combustion.

[@CashedOutCars]

The fix shown here is bypassing the system that does that. Drawing the vapors back into the engine are NEVER good for the engine and actually long term can cause problems on its own

I have the exakt same problem on my Passat 3.2. If i want to fix it properly, what new parts do i need to buy?

[@CashedOutCars]

You'll need to get the rubber PCV diagram if you want to go the cheap method or a full valve cover if you want to go the expensive way. Good luck!

[@balancereplays7722]

isn't this dangerous for the engine. when you stop this leak in creates more pressure in the engine, after that oil will start going through piston going back to the engine,after that the oil piston rings will go bad and you must deal with entire engine repair or change?

[@avgfinnishdude]

this is a PCV valve, the oil that comes through that is basically wasteoil anyways.. its going from your engine to your intake manifold to be burned so it doesnt go to the nature.. when your pcv valve is broken then there will be excess air coming to the engine after maf causing issues with idle there is no harm in this "fix"

[@sara092]

We got the same code on our Passat 3.2 Variant but it turned out to be the throttle body.. Now we have to change it

Is this fine to do in my mk5 r32 3.2? I did it yesterday and now the noise went away and sounds better. I watched how to replace the piece but don’t have the space or time. Is this fine to run for a few months?

[@joshsanders2756]

Also does the catch can fill up quickly, do I need to check that often? Thanks

[@CashedOutCars]

I’ve had mine installed for almost a year with no side affects. Granted, I’d fix your car as soon as you can since the R32 is far more sought after than my Passat. As for the catch can it should fill up quite slow, but check it once in a while to be safe

[@joshsanders2756]

CashedOutCars ok for sure thank you, I noticed too white smoke comes out of the can when the car runs not a lot at all, but if you focus and can see it. Is that normal? It goes away right away it doesn’t linger and if it’s windy out with the hood open you cant see it but smell it

[@CashedOutCars]

It’s oil / water vapor that the can didn’t catch, I wouldn’t worry about it too much, but like I said I’d fix the valve as soon as you could!

[@joshsanders2756]

CashedOutCars for sure, hopefully soon, thanks for the help man

[@preshan.naidoo2589]

Hi did you have a bad fumes issue as well.

[@CashedOutCars]

Hi, if I remember right there was a bit of an oil smell, but nothing too bad

[@EastsideBVC]

Hi. So I made the same thing as you but I have a concern . Is it safe to cap the intake hose that you disconnected ? I mean on the long term as I find it very difficult to tear the engine down for a 20$ part

[@CashedOutCars]

Ideally you should replace the part, since this solution isn't super emissions friendly. With that said, mine has no problems or oil leaks as a result of solving the problem this way

[@CARBON10]

You have to cap the hole on the intake or it will suck to much air , and route the pipe from rocker cover to catch can or down to road as I did, very little oil comes out actually , no bad effects at all, the reason for pipe from rocker cover to intake is to 're burn anything that comes out of crankcase , and perhaps be more environmentally sound People make a big story out of this, it's not at all, but repairing the silly rubber inside rocker cover is ludicrous cost wise ,so revert to age old system which has been on engines since they came about, VW, just complicated the system and it is a common failure,

[@robelbelay1938]

So replacing the valve cover fixes the problem?

[@michaels7981]

It's an option but you can change the PCV valve assembly, change gaskets (03H-103-483-E valve cover gasket, 4 pcs 03H133-237-G intake + 2 03H-133-237-J intake) and re-use the valve cover, other option is changing the diafrags of the PCV they are sold separetely ( in any case still need the same gaskets)

[@adrianoverkill]

it is not a fix it is an unsafe way to avoid a fix - - positive crankcase ventilation is not an optional extra

[@adrianoverkill]

I might add that it is not difficult to remove the v6 Passat (etc) intake manifold and does not need to 'take the whole front end off'.

[@CashedOutCars]

You’re correct for newer VR6s, with the black intake runners. For ones with the silver runners it’s nearly impossible to remove without taking the front end off. Granted, it’s not super hard, but was a bigger job than I wanted to tackle

[@CashedOutCars]

Well to run correctly it is an optional extra, when it’s routed to the intake manifold. Like this, the pressure can still escape, but a catch can is needed to prevent vapors from entering the atmosphere. This is recommended as a temporary solution

[@jbob7148]

Yep, removing the silver intake manifold from a 24v VR6 R32, A3 or Passat is a PIA as you need to remove the front bumper, dipstick tube, pullout the radiator in order to reach the bolts on the bottom side of the intake manifold. that doesn't include removing the throttle body and everything else attached to the manifold. Once you have the manifold off you then need to pull the coil packs, remove the valve cover, open the plastic cover and replace the diaphram. When that's done you need to put the whole thing back together. There's a reason it's an $1,800 to $2,100 repair at dealerships for what is a $3 part.
