The reasons they cannot find the leak is that they are focusing too much on the rear door.
Water in back seat floor bmw.
One is that the sunroof drains can get clogged.
You don t want to remove the seat back just the cushion.
This happens after it rains.
Sometimes i do it with my thigh with my knee on the floor but yours is wet.
I ve had the car back to the dealer who kept it for 4 days over the weekend and apparently stripped the car back and water tested it twice but couldn t find where the water was coming from.
Water in chassis pours into passenger rear footwell.
Pulled up a corner of the front carpet and managed to pump quite a bit of water out probably a few litres.
What i have found is that the water leak is actually from the front door and under the side carpet there is a ledge and the water runs along this ledge and ends up pooling in the rear of the vehicle.
I have exactly the same problem with my 2014 f11 except my floor mat was soaked.
Bmw seats are far easier to remove than most.
The seats are not at all wet just the floor.
There appear to be two major causes for this mine had the more frequent of the two.

The floor behind the passenger seat is soaking wet.
Just push back slightly on the front edge of the cushion about 6 in from the door.
I ve since collected it and driven it for a week.
I m parked in a level driveway.
Water getting in car.
At the same time pull up on the front lip of the seat.
Repeat for the other side.
The car is parked on a slight incline so that the driver side is higher than the passenger side.
