Uh...this little widget thing accompanies many calipers I've seen, 
Audi and otherwise.

Also, it wouldn't compensate for pedal pulsing.  Pedal pulsing is a 
"big" thing; look at the size of that little widget and tell me 
that's supposed to counteract that.  Nope.  It's also way too low a 
frequency; the length of the shaft is short, stiffness of the rod is 
quite high, and the mass at the end is very small. Ding the widget 
with a hammer some time.  I guarantee you'll get a "boing", and not a 
wooob....wooob....wooob noise akin to pedal pulsation.  It probably 
counteracts the high frequency ring/squeal you sometimes get when 
coming to a stop(very soft, because maybe the widget is doing its 
stuff?)

Take it off some time and find out, who knows.  I didn't see any 
warnings in the Bently about "do not remove wenig widgetsache* 
sticking out of caliper!"(of course, you run the risk of disabling 
your left brake light and your glovebox while it's off.)


Wow, this is amazing.  I can actually post to the v8q list 
withou....oh wait, it's not the v8q list...
