Nope, its your door seal. Go buy some clear silicone. Its a 20 min fix .

My money would be on your windshield cowl. is it cracked anywhere like every other e46's? Here is a good DIY, but a wet floorboard could be the tell-tale sign...

Its your door vapor panel, its coming loose inside the door,take off the door panel and check if it came unglued,a poor design from BMW.

yeah... The regulators go out so often in these cars most people who don't know better just rip off the door vapor panel without a thought. They never seal it back on properly.

I've replaced all regulators twice with the exception of the drivers side... I did that one once. I need to redo my panels as well.

I,M POSITIVE ITS NOT THE DOOR SEALS,AS LONG AS THERE ARE IN PLACE AND NOT TORN.
I did not reuse the BMW vapor barrier,got a roll of vapor barrier plastic from Home Depot,they have different thickness,glued them on 3/4 up on the inside of the door,fed them down and worked them inside the door ,where the regulator sits,so if water hits them it runs back into the door,just make sure the door drains are open,one at each end of the door.
