<< I don't know about your vintage, but recent Audis (both 2.8 V6 and 1.8T)
 have oxygen sensors *before and after* the catalytic convertor (yes, four
 sensors total on the V6).  This is to provide the computer with information
 about whether the cat is working.  On these cars, a failed cat will
 generate a fault and stored in fault memory.

That started with OBD II engine systems in 95
