Anyone no how water would be getting inside my boot lid

Inside the lid itself is rear window seal or wiper spindle seal. Window is glues in, so specialist window fitter job to reseal. Wiper spindle needs new grommet.

Inside boot itself likely to be rear lamps where they fit to the body, or the tailgate seal. Pour water around the lamps from a watering can or running hose, no pressure.

No it is getting into the boot lid it's self some how

So screen leak, wiper spindle leak, or another thought, screenwash tube leaking.

or high level brake light or seam arround the top of the lid

Is the tailgate supposed to be sealed? Mine always trickles a bit of water from the right hand buffer after rain. IIRC there are what I assume to be drain holes near the bottom edge so I thought a little water was normal; having said that, my boot release is now playing up.

That's where mine leaks from I don't think this is normal will b taken it apart tomorrow lol and a tube off tec7 will b used lol
