I have a 2006 B7 RS4 with adaptive xenons. Travelling between UK and France I used to make the required "tourist" headlamp adjustment using VCDS without problem. Now I have to get the car registered in France so I swapped out the headlamps for identical units for LHD, refitting the original ballasts. The lights work insofar as they come on but they are not now cycling through the leveling procedure and when I went into VCDS to aim them correctly I noticed "55 - Xenon Range" had changed to "55 - Headlight Range" and when I tried to follow the procedure for resetting the aim, when the car learns where the correct level is again, the options were not coming up as expected.

Is there a code in VCDS that I have to reset to tell the car it still has Xenons? Help would be much appreciated as I can't get the Controle Technique (MOT) I need for registration while the problem exists.
