Wet floor in the back row of Volkswagen #GolfMK7 is a common issue caused by damaged seal of the speaker. #Water draining though the back door is slowly dripping on the #footwell and can cause further damage in the car. To fix this "wet carpet" issue you will need to remove door card and the speaker.
➡️ To remove door card you need to start with interior door handle trim. Then remove two torx screws. There's also a lock that you need to rotate - hidden behind the red reflective plastic. After that you need to pull the card towards you. It's held by 6 clips. With clips undone slightly lift the card to release it from the edge close to the window. You can disconnect all wiring from the door card or hang it somewhere to have access to the speaker.
➡️ Speaker is installed with rivets which you need to drill out. Then you can use knife to remove old seal and replace it with new one. I'm using neoprene tape. Also you can replace rivets with screws to have more control over the force used to hold the speaker in place.
