I've notice a curious thing with the A3, it may be a common thing with VAG cars I'm not sure; the dash (speedo etc) cluster lights up on it's own and it makes it appear that you have turned the lights on (or is it always lit up, just that in the day you can't see it?? Though I'm sure sometimes its not lit up in slightly duller conditions). It seems a strange thing to me, since why would you want the dials lit up without headlights on, as it makes you assume you have lights on! Our previous car had auto lights, so at dusk the lights would come on and so would the dash lights. As far as I can see the Audi doesn't have auto lights but you could be mistaken to think you had lights on because the dashboard (speedo/rev etc) is lit up even though you have no lights on! Can this be altered perhaps in VAGCOM? so that the dash never lights up unless at least side lights are switched on?
