 According to a local Audi master tech he says that the synthetic diff fluid
that Audi uses evaporates at operating temperature.  The fluid level drops,
causing play in the pinio gears, then causing the diff seals to leak... If
the fluid level is kept at maximum level these seals would probably last
forever..  Also since the Auto tranny is heated by the engine coolant it runs
at engine temp, which is rather hot for an auto tranny.  I've seen the
pistons deteriorate because of this heat, this is another weak point...  If
you want to make your auto tranny last install an additional air to ATF
cooler.
