Reading the problem section on here i came across
http://www.mk5golfgti.co.uk/forum/index.php?topic=44709.0
About PCV and DV failure.
Reading other forum it seems the dealers don't really know the cause some just keep changing things till it stops. :sad1:

No one :sad1:

^^^^
Sorry, Geoff - If I knew about such things I would try and help.
Surely someone on this forum would know? Try retitling your thread starting with the words "PLEASE HELP -" in CAPS.

Thanks Robin may try that. :smiley:

Moving on to the PCV valve
This is also known asssss The positive crankcase ventilation valve, learn something new everyday? What does it do? well its meant to allow for gases to escape the crankcase into the intake manifold when there is a vaccum present (or boost or essentially when your driving) When this fails it can cause a few problems which thankfully I havn't had but will replace my PCV valve.
So what happens when this little bugger goes wrong? well symptoms include the following
-A drop in boost with some people claiming 2-3psi
-A decrease in MPG
Oil found in or around the diverter valve, oil cap, valve cover, engine cover and I've hear coil packs.
Now, you might have some of those symptoms or all of them which means quite probably you have a PCV valve failure. The diagnosis for a failed PCV valve is simple, there are two ways. The first is to remove the oil cap or the dip stick for a very brief moment as you don't want to screw up the pressure. If the engine retains its ideal as normal then you have a failed PCV valve (or so the saying goes) but if your engine suddenly runs rough and splutters a little then everything sounds gravy baby. remember you only want to do this briefly, not sit there with a brew saying "oh just one more minute we'll see if it starts to smooth out" :mad: The other way is to check by actually removing the PCV valve and blowing through it on the intake manifold side, if air goes through it without any resistance then your valve sounds dead. Or you could take the hose off intake manifold side to the pcv valve and blow through that.
Mine nearly stalls when i remove the cap.
hum.
