Welcome to the forum

Betterer known as the fish tank. Fills up due to lack of circulation, tailgate window seal not fitted propper or the rear air vents being blocked by foam not cut back propper during manufacture. If its had a rear end shunt then the seal between the storage box metal and the boot floor could be broken. Splashing through water with the plastic cover missing from the floor under the rear seats is another good one. I know from eggsperience of not putting mine back as i used the hole to pass testing cables through. Filled the carpet rear sponge with water after splashing up. Cover provides access to the fool tank pump.
