the only think i can think of is they come on when the xexon bulb burns  check the owners manual or call the volkswagen service dpt and see if one of the techs knows

Pull on the light switch.  The fog lights should turn on.

if they are not coming on they are blown,replace them theu may be daytime running lights,if you do replace, DONT tuch the bulb it will blow once power is on.

I thought they were the DRL's but the DRL's are actually the Xenon bulbs as well.
Don't think they are blown, the car is brand new and no fog lights on the R32 (no room due to the large size of the
3.2FSI engine in the front bay)... weird

The engine is not FSI

holy crap people. the halogens are for when your lights arent on (DRL are on) to high beam people (to let someone go) so not to blind them, having HIDs all the time on will burn the,.. vag-com it or euro switch it.. your 300$usd light bulb will thank you

I am not sure about your model VW, but I have the same on my Beetle and the halogens are used for the high beams.

I think you've got it right here.
