Ok so noticing that I have mould in my passenger footwell (LHD model) and the floor is soaked I assumed the usual that the sunroof drains were blocked...

However on researching this I found that the water is dripping from this pipe connection into the footwell can anybody tell me what it's for? I presume part of the AC system? The pipe is hot to touch. Also not sure if this is associated but I'm also getting the occasional, what I assume is, AC gas escaping through the 2 central vents...
