IF your problem were on a 4kq, i'd say it's something to do with the X relay
(The load reduction relay, that shuts down everything 'non essential' when
starting). But I'm not sure that the urq has that relay???

Light may work when you 'flash', because that bypasses the X relay, and under
certain conditions, can actually 'backfeed' power to the ignition ciruit.

(That condition is that you headlight switch is on, and the high/low beam is
'clicked' on the high beam position.

To set to that condition: 
Have the headlight swith on, with  highbeams on, then shut off the ignition. 
Leave something on when you turn off the car, (like the heater fan), so you
can tell if  the ignition comes on. 

With the ignition off, pull the dip switch enough that the 'highbeam flash'
comes on. When it does, the ignition circuit will also go live!

(THat's a reason that the highbeam flash switch contacts can go bad, as they
can inadverdantly   be switching all of the igniton load)

Aren't Audi electrics fun?

(Maybe not, but more fun than toasted rod bearings! Want to trade problems
Michael?   :-)
