After noticing the car was steaming up a lot, I started investigating for water ingress issues. I removed the boot carpet to find at least 3l of water in the spare wheel well



This is the grommet which sits below the light cluster and carries a few wires (presumably the number plate light wires?) out of the body. Anyway, the grommet was completely out and I assume that's where water has been getting in? Would I be correct in that assumption?
Thanks
