Okay, having just accidentally found the outlet myself (I saw a large, rapidly forming puddle and thought I was in a spot of bother!!!) I think I can help. If you get under the vehicle and look up into the transmission tunnel, roughly in line with the fronts of your doors, on either side you'll see a very short pipe with a small rubber grommet on the end (looks like a smaller version of the 200tdi air filter box drain plug). Pull these off and give them a bloody good clean; these are the drain pipes from your matrix, which is where the condensed water is SUPPOSED to come out.
Hope this helps,
Chris
