I have 2016 Kombi with full tailgate. Water appears following a downpour in the rear O/S around the tie down hoop. The van is carpeted up the sides but the carpet is dry from the bottom 2cm up. I have a fitted floor mat in the rear which is dry on top but damp underside, the rubber flooring is wet on top and damp underneath. With the carpeted side being dry and the van stationary its puzzling as to how the water is getting in, anyone any ideas
