I have just had a nightmare couple of days with leaking in to my X5.
I'm on holiday up in Scotland and the rain came down, sideways and every other angle all at once for many hours.
The passenger footwell was full of water, I mean about 2cm deep above the carpet!
Once the rain stopped, I pulled up as much carpet as possible and got the towels in.
I did some testing and it turns out the front left sunroof drain is blocked.
The car was parked on a hill with the lowest point being the front left.
I also have slightly damp rear carpets again...
Today, in the sunshine I have managed to clear the drain.
I got some straws, duct tape, hot water and cleaning fluid..
and finally, the water came through
absolute pain in the ass!!!
