2004 Mini, rainfall, I think, is seeping into the floor of the driver's side of the cabin. Sucked out almost 4 gallons after a rain storm. And it's still coming in! Can't understand from where. Exasperating. Anyone out there able to help this hapless owner? Tx!........chris

 

Sorry for the damage,they have an issue with the door seal rubber,remove the black rubber easy job,fill the channel that fits to the car with bathroom sealant,replace the door seal rubber on the door frame,clean off any access sealant the comes out.job done,it packs out the seal to stop moisture ingress,make sure you remove all the water from the carpet,leave the windows open to avoid smelly car syndrome

 

check the drains for the sunroof in it has a sunroof. They are likely clogged with debris..
