The Vel Satis I owned had xenons also, and I used to get the same thing happening.
When I read the manual, it mentioned that the dipped beam level gets raised slightly when travelling at higher speeds (it didn't define 'higher speeds' though). It would make sense, I suppose as you would benefit from increased range. And this would remain unnoticed in the MOT test bay.
It may well be the same for your car.
This job should never be complete - the day I think I've done it all, is the day I resign.
Currently in VelSatisfied's garage:
