I agree (and with Sootchucker) - this is normal on all the VW's I have owned - the pinted 'door shut' area is often wet as there is very little to stop it becoming so. The inner water seals are the point at which rainwater should not ingress. The water dripping off the top of the door on to the seats is not uncommon either - well not on VW's in my experience! Its a 'feature', lol!I may be wrong, but I tend to think of that as being part of the outside of the car - I seal the paintwork generally referred to in detailing circles as the "door shuts" just as I would the external bodywork.
To be fair - they are correct!Thanks for the update. It is ridiculous to have these issues in a 2013 car of the year. VW will say the seals are working as long the water doesn't get into the interior..
