My drivers side was soaking aswell, I removed the drivers seat, and lifted the sound deadening months ago and its still not been put back in had to cut it out, as it is in one big sheet.
I found out that the water was coming in a above the pedal and not the door seal.
I removed the scuttle panel and sealed lots of area that looked like the water might come in and its alot better and only slightly leaks if it rains really heavy, still trying to find exact point, I just keep changing newspaper on drivers floor, which is rare now.
I recently got a search and seal liquid that I used which seems to have helped aswell, so hopefully that its sealed and might even get sound deadening back into the car.
Good luck, its very annoying, but I would lift carpet and dry it out properly so it doesn't smell, and in the winter you will find the inside of the car is frozen so try fix it before winter

was a right pain in my arse, water and steamed up windows because of the condensation.
I posted a thread on it a while ago, but its an on going thing.
