2010 LR2 HSE
I got in my car the other day and noticed black mold growth on the passenger headliner, right by the roof handle.

Been doing a little research. I noticed dampness on the headliner by the roof handle(passenger side), Front corner (passenger side), on the floor right where the door meets the floor. Seems to be a leak in the A panel. Have any of you experienced this?

It could be a leak in the drain line to the sunroof (i cant seem to locate where the drain starts on there).

 

Unless your rubber seals are worn, I'd say you have a blocked drain. Got to freel2.com, the European equivalent to the LR2 and do a search for the problem you are having.

 

You can usually clear any obstructions with LOW pressure compressed air, assuming you find no kinks or breaks.
