Did any water get in before fitting the roof rails ?

It's hard to tell, it still had the long plastic strips over it, just not the plug in the hole, it was a little rusted around the edges though!

My 2014 Freelander 2 has developed a whistle! It starts about 30mph and gets worst until at about 60 mph it drives you mad! I’ve been all over the outside of the vehicle taping up seams etc to no avail. I believe it’s coming in via the heater/ ac system. Can’t see anything down the vents but I did a code dump anyway and came up with etc code B1085-77 - something to do with a de-iceing motor. Anyone got any ideas or had the same problem?
