Rob, as you know the headlight levelling on UK cars fitted with Xenon's have to by law be automatic so as to not blind oncoming drivers, so there's nothing you can do from a basic settings point of view on the infotainment screen, but I had heard of a few instances of Xenon's not being set up correctly at the factory.
You can (using VCDS), go into the auto levelling unit and perform a basic settings which enables the lights to "learn" its basic settings all over again, which might solve your problem (if they are indeed too low from the factory). To be honest though, I'd probably be more inclined (no pun intended) to go back to the dealers and let them perform the basic set up again using their VAS system under warranty.
