Tonight when I started her up she started stuttering and almost stalling on idle, seems
fine at speed on the motorway and cruises
fine... However like a diesel on idle??
Could this be a sensor or maybe the diverted system?

-
Do you get a small hissing sound from the engine when you shut down?? under the airbox?
Possible Blown PCV. Mine done the exact same.
-
PCV ??
-
Pressure check valve on the engine Breather, stablize's the crankcase pressure inside the engine. If thats blown, then engine wont idle smoothly.
-
Thanks, that would make sense...
Where is this located ?
Is there anything obvious I could see / hear that would pin point this as the problem ?
Any idea how much these are ?
Funny, I did notice the DV for the first time the other day... is it normally heard...?
(It was on a fairly quiet street with walls either side)..
thanks again,
Z
-
It's located under the airbox, if you find threads on the catch can kit,it should show you photo's on the pcv. Had to change mine recently.around £30 from memory.Mine done the same as yours has .
I'm in Southampton as well if you want to pm :wink:
-
Out of interest Steve do you know the part number for the PCV valve? Guessing you had the latest revision?
Need to replace mine as it seems to be purging quite a bit on idle. Could do with getting the new seal and connection pipe between the unit and inlet manifold while I'm at it.

Part number is 06F129101L £26.78+vat
-
Is that the part number for the 2.0 turbo Fsi?
I was quoted ~£55 when I ordered one on Friday!
I just asked for a PCV for a MK5 Gti.....
Thanks Z
-
You could go directly for the BSH PCV fix system.
Dubtek on here is a trader and supplies them. £65 ish delivered....and you don't have to worry about the PCV blowing or leaking ever again. :happy2:
-
Can you tell me more about the bsh pcv fix system...
Sounds interesting...
Does it remove the standard part alltogether and replace with a bsh part?
Thanks, Z
-
Here you go Z.

Excellent thanks, I'll order one of those up and give it a try.
I noticed today that it is back firing when coming down throught the rev range on gear change.
Especially at 2000rpm...
There is a real stink of fuel also, so something it making it run far too rich.
I'm hoping that it's ok to drive like this and I'm no doing it any damage as I'm still doing ~40 miles a day to and from work...
Thanks for all your help,
Z

When my pcv valve blew, the hole in the side of the housing was venting to the engine bay. That intern blew into the cabin, a smell like an exhaust/fuel leak, but once the valve was changed, it went. What your smelling is the fumes from inside the engine. Making it smell like your saying :happy2:
-
Great, sounding more bs more like we've pinpointed the problem..
I noticed that the engine noise and exhaust is a bit louder than before as well.
Thanks for your help,
Z
-
Just for the record, mine was missfiring on throttle back aswell.
Did you listen for any hissing sound after you shut the engine off under the airbox?.
That'll be were the crankcase pressure will be blowing into the cabin.
-
Not getting any hissing on shutoff, but have noticed the DV to be noisier than usual as well as the exhaust note.
Engine management light came on tonight.. Should I be worried?
I have to take the wife to work tomorrow, no other option...
However my bsh pcv revamp and stage 2+ catchxan kit is at the postoffice and I'll get it fitted tomorrow..
All going to plan and she should be back to normal before lunchtime... :happy2:
Otherwise it's something else :scared:
I expect the engine management light won't just go out on resolution of the problem and will stay on until reset using vcds??
-
^^ you may find it will go out, but the fault code will stay logged untill its cleared by vcds :happy2:.
Is the car remapped? and have you ever removed it to check its condition.
They are a known weak point (DV's) on mapped std GTi's and should be upgraded to a later version of valve. Later ones were more durable.
If thats failed, then you would of noticed poor boost.
Fingers crossed this works :happy2:
Keep us informed :smiley:
-
Well the catch can kit arrived; collected it yesterday morning at 0700 ready to get it installed..
However I was raging to find that there are parts missing and it's about as much use as
a chocolate fireguard right now...
The 3 x screws that hold the inlet Manila isolation cap are missing..
I also discovered that the instructions are useless and that that the fitting is not meant for a UK car..
So not very pleased right now...
-
Just put the oem Pcv in fella. Forget the catch can personally
-
Too late, I already bought the catchcan kit.
At least it's going to stop this happening again.
I don't have a map, but planning on a bluefin pretty soon.
Going to get a service and fault check up before that though.
Should I be hearing the standard DV hiss on gear change?
If I were to replace the DV what is the best on to replace with, oem or an uprated item?

Oem. Later version is better

So, I decided to have a go at fitting this £180 piece of Kit..... although i'm still waiting for the set screws to arrive from Dubtek...
Found some screws that will fit in the meantime...
To be honest the whole thing has been a disaster... and from what I've read not the first time from BSH..
Pros
- Good, solid quality machined adapter plate
- Large, substantial catch can
Cons:
- No hose clamps supplied (BSH claim not required, but leaves the product unfinished in my opinion and for all the cost should be included for a professional product).
- OEM hose does not fit correctly over the nipple supplied and leaves some risk of vibrating loose. I have secured with tie wrap.
- Missing parts (screws) (Dubtek's issue)
- Unit not designed to fit UK car (Charcoal filter in way, therefore supplied bracket is useless).
- Insructions are useless
Not impressed, and had it not cured my idle and PSV issue completly I would not recommend.
-
So did the New PCV improove your idling issue Zub??
-
I don't have a new PCV... It has been replaced by a BSH catchcan..
And 'yes' everything you said in the post is correct...
Idle
Smell
Backfire
100% the OEM PCV was the issue...
Thank you
-
Happy days :drinking:
Oem pcv to install :wink:
-
Take it you didn't see these threads then :P

Glad you got it sorted mate :happy2:
-
Should I be hearing the standard DV hiss on gear change?
Yes
really Steve ?
I have to say with a standard intake I think I have heard my DV release only once since I bought it.
Only really can be heard on cars with intakes
-
i can hear mine everyday john :stupid:
-
Waste of money catch cans imo.
yet to hear or see a GTi with intake issues due to blocked induction system, plenty of scary photo's but still no failures in this country with the fuels and engine oils we use.
Now wheres my Tin helmet :signLOL:
-
Zub, you should have just gone for the BSH PCV fix and not the full catch-can. It would have sorted the issue and only cost £65 :happy2:
-
They didn't have the pcv kit in stock so next best thing was to go for the catch can kit...
I'll post some pics soon of it fitted, very pleased with final outcome...
Looks very oem
