I have a 2020 Discovery Landmark.

I have a water leak where water accumulates in the driver side footwell. The water is coming from underneath, it gets wet underneath the mat, the top of the mat is dry.

It is my understanding this might be caused by the sunroof drainage tube being clogged, causing water to drain inside the car as opposed to outside.

Could someone please advise where in the car I need to look to find the drainage point? where do these drainage tubes run?

p.s. windshield was recently replaced and is ruled out as source of leak.

Thanks in advance.

 

Try the attached picture which shows where the drain starts in the sunroof but unfortunately not where it discharges.
I would try blowing air down it and maybe listening for the exit. But it doesn't look like it's going to exit in the front footwell.
If you don't have a compressor maybe you could use a can of air (as sold in office supply stores).
If you find the exit point please let us all know where it is.

 

Are you sure it's not the windshield? That's a knows issue on these vehicles. Depending on how the water runs down around the glove box / A pillar it could appear to be coming from underneath.
