Cayenne 955 2003 - leaking into rear pillars

[Awale23]

Ongoing issue and really frustrating now. LEAKS!

I taped up the roof rail tracks as I got advised it could be that which is causing water to drip into the rear boot compartments. But it’s rained and it’s still entering in.

Boot strut drain holes (small ones) I have cleared. Can anyone else think how water is entering?

Could it be the rear rear windows?

Is it leaking from the rear lights?
Mercedes had an issue with the ML where some of the rear light seals were defective allowing water to track down the back of the rear lights into the boot and onto an expensive box of tricks.

I have checked and hope. Leaking both sides down the airbag and dripping at the bottom of it?

Quick google suggests spoiler trim panel as well as the other leaks you’ve suggested:
