Hey guys, 

 

Got an 06 TFSI VRS was starting to have a slightly lumpy idle, knowing the PCV can be the culprit I opened her up and sure enough the diaphragm was split 

 

Ordered what seemed to be a decent pattern part off eBay with a new gasket etc but the shape was slightly different and the internal valves also were different. After fitting the engine seemed to be struggling and started intermittently shaking, doing a quick diagnostic it showed a lean code. Took it off and put the old one back and and cleared the code, gone back to normal and code hasn't come back. My code is on the pic attached..

 

Anyone else encountered this? Going to bite the bullet and buy OEM I think!

Would be interested to see how you get on with the OEM part as this was something I have been considering changing,

How easy was it to get off?

Very easy mate...

 

Daft engine cover off, two screws to take off the air duct. 

 

Then unclip the two pipes going to the PCV then 4 screws holding it on. 

 

Getting the OEM valve next week so will let you know.!

It's an easy job.

 

I circumvented all these issues years ago and fitted a catch can.

Hiya,  could I ask what the revision number on the new part was? 

 

I'm looking at doing the same (on a 57 plate), I've got an F rev currently same as yours by the looks of things.

Hi Jamie,

 

See picture attached mate, No direct part number matching anything Skoda but might give you something to go off. The eBay description matched my Skoda F part number, they have refunded me now. 

 

 

The suffix-F part appears to have been superseded a large number of times, and currently seems to be at R (using this site repeatedly: https://oemwolf.com/).

Thanks Alan, shame - I was wondering if what you had was the P revision (which required the back side valve, replaces the rev G line) or the R (apparently latest to replace the F?).     Hard to find proper pictures of the two to compare, guess I'll bit the bullet and order the OEM R version to try

 

Wino - yes, thanks that's why I was wondering which one Alan had as the replacement, from lots of reading there are two revision lines which may or may not need the rear PCV pipe changed but I can't find any proper confirmation that my 57 plate (with the F revision) will work with the R without that back replacement.  I'm guessing it will but.. 

 

I could of course be completely off base ha.

Just in case anyone was following this, not sure if the 06 system was the same as the 57 but on mine I've swapped out an F revision for the latest R revision (genuine part) and it works fine.  Not noticed a massive difference but then wasn't particularly bad to begin with.  I took the old PCV apart and it wasn't too bad but there was a small split in the diaphragm so definitely was worth doing.

 

It might be completely unrelated but I was having a squealing (like a belt or bearing) coming from the engine when accelerating hard (from around 2-3000 RPM), definitely not right as it was a new, horrible noise. Checked as much as I could visually, the PCV change was part of diagnosing that as have seen several threads on it.  Nothing changed immediately but now about a week later the noise has completely gone.  As I said I can't attribute this to the change definitely, it might be weather or something else (car is going in for a cambelt, DV and various checks this week just in case), but who knows

Hi Jamie, 

 

Thanks for that, I've had so much going on recently I'm only picking up my new one from the dealer tomorrow! It is indeed an 'R' code now. When the PCV goes it's meant to make a squealing now but I haven't got a noise from mine that I can tell, that's with a large diaphragm spilt. 

 

Mines definitely holding back at lower revs were the pressure is meant to be at it's highest in the system and the MPG has dropped a decent amount. 

 

I'll let you know later this week how I get on :-)

 

I've done my cambelt and chain now plus a revised piston DV and cam follower... cost me a small fortune upto now. How's your chain doing?

 

 

Hi Alan,

 

Yeah, it's been a bugger to diagnose, sounds most like a belt slipping or a bearing but it doesn't do it stationary, only under load which suggested something turbo/pressure related (to me at least).  Then again it was really cold when it started doing it and has been nice and mild since last week so that also might contribute if it is a hose or something split maybe.  Dunno   Gave it a few nice bursts earlier today and noise is completely gone for the minute, frustrating as I've literally just booked in with my local to have it looked at.

 

It is definitely not as eager as when I first got it, hence the trying to bring as much of the wear parts up to latest revisions etc.    I'm not sure which DV they'll order in for me yet, will have to check what they get recommended from Skoda.  Haven't looked at the chain yet, that'll probably have to wait until next year now but definitely on my list.  I asked the guy when I rang up earlier and he said he'd never heard of changing out the FP cam follower...   I said I'd get back to him   It's not a specialist garage so fair enough but they've always been good for the basics.   I'm sure they can manage to see if any pipes are loose or obviously split..

 

Did you do the follower yourself?  I looked into it and the only bit I couldn't work out was if the TDC (I think that's it) needed doing to line up the cams, not sure I can do that.

I hate random noises it makes me so paranoid!!  I've had 5 Impreza's so I'm used to hearing strange noises that come and go!

 

If your chain isn't noisy then I wouldn't worry for now, mine got worse (noisier) over 6 months or so.

 

As for the DV they will give you the uprated piston type like in my picture... note the other picture with the old split one. 

 

I'll add pics of my Cam follower too, mine was on the verge of starting to cave in so an essential maintenance item to change considering the damage it can do! Very easy to change if you take your time, don't worry about getting it to TDC. It just puts less pressure on the spring inside the HPFP if it's in TDC due to the Cam lobe pressing on it. Only hardship is the connections on the bottom of the HPFP, if you have 2 rubber hoses going into the bottom then it's easier but if you have a brass connector it's more fiddly. I'll add a link to the guide i used below. 

Worst one i had was a bad rattle at idle that got worse with a bit of throttle, thought it was the flywheel but out turned out it was the fuel lines coming through the channel from the back of the car through the bulkhead!

My chain tensioner not doing it's job!

What chain?

Jamie's chain on his VRS...I.e is it noisy

Well... Got my new R revision PCV and gasket today and fitted it before. I disconnected my battery for an hour to help it get the readings right again. 

 

So although it did feel slightly different I won't be able to tell for a day or so if anything's changed.

No, you said you had a cambelt and a chain and for the life of me I didn't know there was a chain as well as a cam belt on the same engine.  I thought EA888 were all chain and the earlier TFSI were belt only.

Ohhh I see sorry, yeah unfortunately the TFSI has both :-( I didn't even know and I drove hundreds of them when they were new!

 

I'll be selling mine after Xmas but all this expenditure will make it a decent buy for the new owner. Chain was nearly £500 as was the Belt and Pump, not to mention all the other work.

Ha, can't say I've ever driven anything like that but my ancient 1.6 megane certainly gave me a few trouser-changes with all electric cut outs while doing 70 and radiators exploding, I'm almost over the trauma after 15 years

That's good to know, I can't really tell but there's nothing I'd say noticeable from that side of the block.

They got the rev G which is the uprated diaphragm version I believe and bloody hell has it made a difference, so much more responsive I wish I'd done it sooner now.  Also fixed the P0299 Boost Pressure: Control Range Not reached which I've had since I've been able to scan for it.  Happy with that.

That's cool, that's the guide I saw before where he said did the TDC but if it isn't strictly required I might take a look.  Think I've got one solid and one rubber pipe but would have to check closer.

Haha, at least noises when idling you've got a chance to listen for and find.   Still getting the squealing on acceleration although can rule out the cam + aux belts for the minute.  I'm starting to think either turbo sticking, but no loss of power/smoke and would think it would happen more often and continuous - it's definitely intermittent and I can make it go away by easing off.  Another thought is a small leak somewhere but hard to diagnose because it only happens when moving!  The garage who did the cam belt had a quick look at turbo and pipes but it probably was a very quick look.  Think will need to get it into dealer or a specialist to take a look :(  Hate driving it like this but no choice and even more annoying with the DV change which must have brought back a few horses

 

Thanks for the info though, really useful.

You're welcome mate, if you need any other help I'll be glad to help if I can :-)

 

I think the problem is that with getting the car boosting right again it'll highlight and other issues that have come about. You could get a smoke test done that would show up any holes etc in the boost pipes. 

 

In the past I've just taken as many hoses etc off that I can see and inspect them before handing money over to a garage. Have you got any codes? I use the torque app which gives me real-time readings, this has helped me many times on many cars track problems down. 

 

Yeah I'll probably try to get off any hoses I can get at and check for splits etc. before I pay out anymore, I've already had a good look around but no substitute for reseating them   Annoyingly I just took it out for a good long run and it hardly did it at all (just a bit on joining an A road but not when cruising), felt really great too hehe, possibly even better than I remember from when I first got it. The only difference from earlier in the day when it was doing it really bad was that I have a full tank of petrol.. hmm.  Or maybe the rain.. humm.

 

The only engine code now (scanned with VCDS today) is a P0441 EVAP incorrect flow, but I've had this off and on for a while now, replaced the charcoal canister and pipework and I've got an N80 valve to swap out when I get a chance.  That app sounds like it might be interesting, VCDS is great but its a bit of a pain to lug a laptop and get someone else to record.

Could always disconnect the battery for an hour to reset the system too

 

How did you get on with the new pcv Alan?

What was the eventual part number you went with and how much did it set you back?

Cheers

Sorry Munford! Funny enough I was thinking about updating this when I was driving home last night. 

 

Well...I have to say the the car does drive a lot smoother now. Before, the idle was a bit lumpy when stationery and it was a bit jerky at low revs. I believe the PCV valve is most at use when the car is either idling or at low revs so makes sense. 

 

The car seems to have driven enough miles for the system to update itself. Definitely should be a service item.

 

I ended up with the part numbers below..

 

PCV - S06F 129 101 R  £32.29

GASKET - S06F 103 483 E £18.46!

 

That's a lot for a gasket especially seeing as the old one looked fine but I'm a bit OCD so had to get it.
