Finally managed to call my local dealer today! sorry for the wait.
I was told that you do access the adjustment though the panels in the wheel arch as I mentioned the other day. You have to take the rear of the headlight off to access the adjustment screw.
But.... I was told not to attempt to do it, as you could do more harm that good.
I was told the xenon beam is low and wide and you would have no problem driving aboard.
If you do want your lights adjusted it will be approx. 30 minutes labour for each time you have them adjusted.
Bottom line was....don't bother!
