Hi all I'm new to the forum with my 520 d GT - but had the same question about driving in Europe and headlight conversion for driving on the left.....
I found this old thread and a more recent answer from different forum and this works for my 2015 F07 (see below)
Get in the car and don't start the engine but switch it on by way of the button (i.e. don;t touch the brake with your foot) Note, this will not work either on the move or with the engine running.
Go into iDrive, settings and then into lights, headlights and finally headlight adaption you'll then see an option for changing the beam from left to right.
Just incase any one else has the same query - ymw
