Locate the PCV on the engine and check whats happening with the pipes connected to it? Like a vacuum being produced in the crankcase, am no quite sure but take the oil filler cap off the top of the engine and see what going on there. Might be excess pressure there, possible blueish oil mist. If the PCV valve is iffy do you get smoke from the exhaust?

All done now, after the dealers giving me the wrong revised part it's all finally sorted.
Here's the inside of the original, pretty much ripped in half...

Also caked in oil...

Is that squealing coming from the PCV? I have the same sound but its very 'fade in and fade out' and not often constant. I took it to VW and they charged me £65 for the courtesy of telling me it was the clutch release bearing. Now recently I've had some vacuum loss issues and you can hear the leak coming from the engine bay... After watching that video I think the noise that VW told me was the clutch could actually also be the PCV!!!  :angry:

The squealing doesn't actually come from the PCV but is caused by it. The actual noise comes from down behind the engine really confusing things.
The noise on mine got worse as the engine warmed up. I too thought it could have something to do with the clutch or gearbox because that where the noise seems to be.
Anyway change your pcv, it's that and make sure they give you the correct revised part.

ALSO!! If your careful enough, you can pop the lid off the existing pcv (careful not to break tabs) and check the rubber diaphragm inside. If it's ripped there's your answer.

I finally got round to replacing my PCV over christmas. I reset the engine management light and am now some 700 miles or so later and it hasn't returned. It used to come back after about 200 miles. I haven't had my usual rev issues on idle either, so everything points to it being fixed!!

Also the noise that VW told me was my clutch release bearing has gone too. I'm well chuffed with that!! A £30 part which took 5 minutes to fit has solved all the problems on my car  :grin: Obviously replacing just the clutch would have been more than 10 times the cost which VW were encouraging me to do!!!
