Well after a lot of head scratching - both mine & Trups we ran out of ideas of how to activate this function. Trups had done the coding but as the layout has changed beneath the dash we didn't know where to put the repair wire. I believe Wes was on the phone saying he didn't think a wire was needed. Anyhoo, after giving my car its first ever wax I also dusted the interior (not that it needed it being less than 2 weeks old) but I knocked the high beam stalk. Not thinking anymore of it I decided i'd put the upgraded bulbs in the fogs to match them closer to the xenons and noticed the fogs and LED sides were lit... Mystery solved. Like my Volvo V50 I chopped in for the Audi, to activate the follow me home lights, flash the headlight stalk, lock and walk away in a flood lit path to your front door. Obviously you need the coding for the feature to appear in the DIS, but once done, no wire is needed. NB: As yet I haven't managed to activate the lights when I unlock the car - maybe this does require the repair wire?? UPDATE: just been informed if you install the repair wire the above & approach lights will activate everytime, day or night without flicking the stalk etc.
