Not sure if its the same as the 1.8T but the 2 pipes going to the heater matrix (Under plastic covers by battery) the left hand one needs to be pulled back enough to reveal the blow hole, when water starts coming out then the system is bled. If it doesn't work then it Could be a water pump problem not pushing the water to the matrix

what do you mean blow hole ,like a bleed screw and the i have replaced the water pump with a new one

imagine the tube with the pipe over it, when you pull the hose back (like a sausage skin ) there is a little hole drilled in the metal pipe (I just call it a Blow hole as it reminded me of a whale, i'm strange, i know!! ) when that is revealed it allows air to escape. it does on the 1.8T anyway.

Hope this helps.
