Sunroof lower drain hose

Hi
So here i am with my so unusual issue : water pouring on the passenger side from somewhere between the glovebox and the body.

After trying few things it appears that what leaks is the lower part of the sunroof (panoroof) right drain pipe.
Found this topic about the upper part of the drain pipe, which plugs into the leaking one.

https://xoutpost.com/bmw-sav-forums/...-kink-fix.html

Very nicely made topic, unfortunately not cover my case because this rubber hose in the A pillar is completely debris free.

The lower one (looks like made from hard plastic) must be leaking somewhere because when i pour water in the front right drain hole of the sunroof, it drips inside (like i said somewhere around the glovebox).

Is there a way to access this hose without removing the whole dash?
Any way to remove the glovebox bloc?

Thanks

Did you remove the A-pillar trim and look at the upper drain hose? Not clear from your post...If you haven't, you should start there.

It's possible the rubber hose got disconnected at the sunroof. You can lower gently the headliner on that side and take a peak. You will need to remove a few things that hold it in place.

For me when water was in glove box the rubber hose got kinked and it overflowed in the sunroof cassette from the sunroof -> down a pilar-> glove box and LCM but if it disconnects i would assume the water would take the same/similar path.

Sorry if not really clear, but yes i removed the A pillar, it was all dry in there. Blew in the upper rubber section of the pipe, all clean and no resistance.
So the water is passing this hose, and the issue is lower.
Will remove the glovebox and have a look behind.

Well, to stupid problem stupid solution..
After removing the glovebox and realizing that it doesn't help much, i thought that maybe the issue is lower.
So went under the car, put a screwdriver in the evacuation hole, aaaaand it's gone...
Was full of gunk, now it's dripping fine.

Work smart, start low!

Now the drying of all this damp carpet is another topic..

Interesting...

I wrote the DIY that you linked above...

Step #6: Drain Exit next to jack pad: overhere I cut the leaflets a bit to prevent debris from clogging the bottom.

In any sunroof (no matter what car/model), the seal between the glass and the opening is basically a piece of felt, it is not water-tight simply bc the glass slides sideway, so the felt seal is there to keep 98% of water out.
However, there is always a 2% of water (and grime/dust from the atmosphere) that enters the channels in the sunroof cassette.

This is why it is good practice that one cleans the channel with water and some q-tips once a year, especially if one parks the car outside under the trees.
Knowing the X5 sunroff system, don't open the SR too much (lol), just a few inches to pour water in and clean it, especially the front drains...

Someone told me to lube the outside seal up top but I can’t remember what he told me to use. Something to keep the rubber from drying. Do you happen to know what should be used? Sorry to hijack
