URGENT help water leak - coming from bottom of driver side door

hey all,

just appears to be problem after problem for me.

anyways, washed my 2000 318i sedan today, and noticed a water leak.

originally, it was pouring in from the top of the driver side door, because the outside plastic trim going along the top of the doors wasnt sealing right, so i sealed that now thats fine.

but now i have noticed water is coming in from the bottom, and as you can see the water line running down the carpet.

i am completely stumped how this can be getting in, when there is a door seal on the inside and outside, and they look like they are fine :S
can anyone help?

i have uploaded as many pics as i can to help.

help with exactly what i need to do, where to seal etc would be heaps helpful.

thanks guys want to fix this asap

the arrows show where i can see the water is running through then down the inside of the carpet.

There is a sunroof drain, and it can get stopped up.

I have only read about it, but I have no experience with it, so that's all I got.

Hope that helps your troubleshooting.

3M windo-weld is what BMW recommends to seal between the vapor barrier and door.

You can check the whole shadow line trim, sometimes the clips are broken.

Did a bit of searching on the vapor barrier, it says if this is the issue it's common to sit under the dash....

For me appears to be going directly under the driver seat but not sure

Don't see how it could still be that if water is seeping from the bottom of the door
