Water leak on drivers side

[Stu]

My Passat has developed a water leak but only the drivers side is wet, but when I say wet I mean water is above carpet level!!!! I had water dripping on my feet whilst driving the other day!

So far I've sealed up the doors and am in the process of stripping out the scuttle to see if I can spot any thing.

I would be very very great full of any tips of how you've sorted a wet passat out
