Having suffered from a detached linkage on the windscreen wiper arms I have been working under the scuttle on my 2011 4.4 TDV8. On the drivers side there is a drain tube attached to drain around the wiper spindle boss but nothing apparent for the passenger side. There is a hole (which was full of muck) and it just appears to be draining on to the pollen filter housing. I have messaged a breaker on Ebay but the vehicle they are breaking does not have one fitted.

Yes there is one fitted, here is a pic of the lower end when I was replacing all my brake pipes.
It exits behind the inner plastic wheel arch. You can see the end at the top of the picture.
