well, i finally got the time to phone VW to order the PCV part, he didnt have a clue what i was goin on about lol. i had to come on here and get the full PCV meaning and tell him what the part was used for. we got there in the end, it costs £33 plus vat. out of interest i asked how much to supply and fit the part, he said it would be £135 as its 90 mins labour. i said thanks but no thanks, i will have a go at it myself at that price
