Design Fault

Hi,

First time on the forum having just become the owner of a 2018 A5 Coupe and had a peculiar experience first time out in the rain. Returned to the car and opened the boot. All the water on the boot ran off onto the rear screen, down the screen, over the little plastic strip (designed to re route water) then straight over the water channel and straight into the boot. Has anybody else experienced this. The only way I got around it later was to hold the boot partially open until the majority of the water had gone then open it fully. Not ideal in torrential rain storm.
