Anyone know what this clear hose is? Drivers footwell & A Pillar

It's right up above the pedals, is clipped to the firewall and runs out through the firewall.

I think this is also leaking. I have traced it back as much as possible and seems to run up the A pillar alongside the sun-roof drain.

Only a guess but if it's carrying water it may be the washer feed to the rear window?

Does look like a washer tube

[Coxy]

great stuff, you might be right!!

Confirmed, when using rear washer you can see bubbles flowing through this tube

Thanks very much, one down in the process of elimination.
