Volkswagen Sharan TDI?

Hi, i have a VW Sharan Tdi 2000/ W reg, i am getting water on my front driver floor (all carpet is wet on this side front) i have cleaned the front scuttle panel by the wipers and cleaned the channels, i have also changed the seal on the frame around the driver door (not the door) but i am still getting in water, it is not the sunroof model. Can anyone help me in this puzzle.

Kind Regards
