As of VCDS Release 15.7.0 it is possible to perform Basic Settings in address 09-Cent. Elect.  This procedure has received limited feedback to date so Paul's [http://www.a5oc.com/forums/audi-a5-s5-tech/97369-new-xenon-range-adjustment.html New Xenon Range Adjustment Procedure - HOW TO] thread may be helpful.<br>
