Tired of the leaks, proceeded to seal with silicone under the lip of the sunroofs black plastic bezel that sits on the roof top and fully shows a good adhered bead all around, also and consciously sealed all the glass edges with duct tape covering from glass to roof.
Carefully inspected inch by inch for any pores, lack of sealant and there is none. It is thoughtfully, carefully, well sealed.
But still rains inside. WTF ?

 

Where are you getting the water inside

 

I fought this dragon and finally won. Get some clear silicone and on each corner of the windshield under that curved trim piece put a nickle size glob.

 

Yep, look behind the door seal in the top front corner as well

 

Here is the Land Rover TSB on the windshield issue

Thanks.
Water drips to the gear shifter from the sunroof switches trim,
by the 'garage door remote' buttons to the radio,
and wets the liner on the side by the rear right passenger head above the door, inches front of the C pillar.
Almost never driven while raining; happens mostly parked level. Nothing gets wet by the front windshield.

 

Shucks, that sounds like sunroof drains

 

This may be important...
With all the 4 sides glass-to-bezel (1 to 3) gaps sealed with duct tape, and the bezel edges also with a silicone bead to the roof as I never use the sunroof, I do not want it, I hate it.

Still leaked. Apparently the rain gets under the marked-red plastic trim and flows inside helped by the slight slope when parked level.

Placed a bead of clear silicone along the green-marked line. Started to rain, and for the first time, it is dry inside !
Will add a picture tomorrow...

 

That might explain the phantom leak I have
