    It may be a breather pipe. You may need to clean all the breather pipes out, but this may not solve the problem (if in fact it is a problem) this pipe may well be for the purpose of moving pressure away from that area.....

    Pictures may help too. It would help identify exactly which pipe you're describing.

    easy, the plastic housing will be cracked and spouting steam under pressure.

    Was it that hard to see and help people to help you? without bumping the post every few hours.

    A photo would have answered this immediately , however I am familiar with the 1.8t and can confirm it sounds like the plastic housing either split or the head to housing seal has gone
