There's a DIN standard that defines the function of _all_ such numbered 
contacts in German cars.  I think one of the listers was trying to obtain a 
copy ...
 
If not, I'll dig out the designations tomorrow.
 
Bear in mind that the list is split roughly 60:40 on the subject of loading 
Audi light switches.
 
60% think it is criminal insanity to add more load to a stock Audi lighting
    circuit.
 
40% think Audi is criminally insane for using such feeble switches and
    wiring for the main lighting circuits in the first place. 

If you want to add lighting watts, ya gotta add wiring and switch capacity.
