seen on MTORQUE:
"i asked about this a while ago and there was very little information from anyone on here. Since then I have been into my local dealership having had rung them on my way to the continent.
An engineer came out and showed me the adjustment point. To locate the knob you will have to remove the black covers on the back of the headlamp unit. Inside you will just be able to see and feel a little white stalk which is just off centre of the headlamp at the 9 o'clock (R headlamp) position and 3 o'clock position (L headlamp) as you look at the front of the car. When these are pushed down they are set for use on the continent and when pulled back up they are set for the UK.
Both are difficult to reach especially the L headlight for which you must pop the windscreen washer tube out of its holder."
thanks Nords
now i need an engineer to turn the knob
