Hi all. Another boot leak thread I'm afraid.
Been looking through all the other threads and have a handle on the usual spots:
•Upper boot door hinge
•Boot seal
•Towing bar mounting point

The problem with my instance is that it only happens sometimes. Being in Scotland, there is plenty of rain, but I can go ages after hoovering out the puddle before it just appears again.
Both side pockets are bone dry but I did notice once that the edge of the boot carpet was wet but no other carpeted areas.

Does anyone have experience of the same and which area to concentrate on?
I'd like to tackle this this summer to give me one less worry.

Cheers. ---------------------------------
