Right all, update from 3 Audi dealers today, all of which stated the same as cuke2u above, that at least on my spec (sline with non matrix LED lights)they are flat beams and as such do not direct light to a particular side.
Took a bit of toing and throwing, and getting past the initial standard "ifs not in the mmi, you will need to come in" all those that I spoke to had checked with one of the Jedi qualified techs, and in the last call, they had actually had to do check it the day before with the workshop manual when someone had gone in with the same query, and it stated no need to adjust for continental driving.
And as nickgun says will find out next Saturday evening for definite!
