I know this is a common prob with vr vs, I have a leaking boot and i am just wondering what causes this issue
Rear or side window seal leaking.Also the tail lights can leak and let water into the boot.My tail lights were leaking when I first got my car.I fitted different tail lights and it stopped.It can also get in through the bootlid if you have a spoiler fitted to the lid.Apparently it leaks in where the spoiler joins the bootlid.Just get in the boot with a torch,close the lid,and get someone to hose off the car.That should show up where its leaking.
it will leak when you lift the boot lid. as the drainage holes are not in the bottom of boot lid to allow adequate drainage. get the good old cordless out with maybe a 5mm drillbit and drill 2 little holes either side of the centre just out from where numberplate is. this will allow for the water to drain out onto rear bumper so that when you open boot it wont gush into the boot.
that is ofcourse if that is a problem in the first place if not ignore what i have just said
good luck champ.
