Forgot the last part of your question. I guess if the sensor is 
self-cleaning there's less need to clean it. If the car has 100k+ miles on 
it, I would take the sensor out and inspect it. Clean if necessary. - 
Especially if you have trouble passing smog. If the car runs fine, don't 
mess with it. If it ain't broken don't fix it.

I would, however, be surprised if Audi used self-cleaning sensors on one 
model but not on another. How do you know your sensor is self-cleaning?
