My '91 200q20v has a rear fog light only on the left side.  I believe that
is the way the car was delivered from the factory.  As previously discussed
here, a *single* bright rear helps to distinguish the rear fog from brake
lights (equal brightness, but two of them)  That there is wiring there may
be so that Audi can rationalize their wiring harnesses for RHD countries.
Or, a PO may have added the wiring and changed the socket from the tail lamp
socket to the tail lamp/fog lamp socket--i've heard of this from a guy down
in portland.

i guess the next test would be to use two known good bulbs--do you then get
l & r rr fogs?
