I've had a few problems occur on my 2006 VRS 2.0TFSI over the past few days. First off was the engine managment light came on and upon popping into the skoda dealership was told that a component associated with air regulation was not configured. The operator configured it with the car and the light was reset. Since then I've had no more lights on the dash but the car stutters, only slightly but noticable at all speeds. If I try and coast in gear you can feel the car pulling back slightly giving a juddery ride. When sat at junctions the car searches slightly and the car judders randomly rising the revs to 1500 then dropping back ( a boy racer today thought I was tempting a traffic light sprint )

Now I've read quite a bit about the PCV problems, so is this likely to be the symptoms relating to this ?

Keen to get this resolved as its like driving with my grandad and his kangaroo throttle control

I'd definitely change your pcv valve as a first step. The part is only ~£30 and you can fit it yourself, hardest part is getting the engine cover off (not to be underestimated!)

I had similar symptoms and swapped mine, though also in conjunction with spark plug change, which cured it.

Well earlier in the week after no further help from the dealership service dept I decided to ignore their advice on a new throttle body and try a new PCV valve ( rev N ). I didn't hold out too much hope as I had tried the PCV valve test detailed on various sites, suggesting by removing the oil cap quickly and seeing if the engine struggles to run. This test suggested the valve was working, but as I had already ordered the part it was still worth fitting it. The part arrived yesterday and I installed it today. Was a very quick job and yes the cover is a pig to remove as no one likes to force anything for fear of snapping something. I replaced the PCV valve and a new gasket and refitted the cover. Upon starting the car the engine sounded much quieter and smoother than its ever been since owning the car ( 5 months ). Revs now sit comfortably below 1K and at junctions the engine fan is noiser than the tick over so really pleased. No more stuttering and random revving.

Yet again it shows how helpful these sort of forums, highlighting how if left to the dealers I could be left chasing the fault with a diminishing wallet.

So I would reiterate all before me, given a lumpy tickover and random revving, for the sake of £30-40 replace the PCV first before looking at the more expensive options.
