Rear quauter panel of side water WHere does it come from ?

In the boot on the right looking at the car from the rear, is a removable panel with a fuse panel.  Took the cover off to put in things I need for emergency and its soaking.  The sponge below the fuses is wet through and the well underneath is wet.  Any clues where its coming in as the boot seals look ok

Check the rear light seal. If its that they are cheap from bmw.10min job. Mine leaked the other side for ages then one day stooped! Good luck.

Thanks that's does seam to be the culprit as the fuses are ok above the wet area
