Actually, Hans, Tiptronic is the regular Audi automatic transmission with 
manual shift feature. Their version of the
DSG was called S-Tronic. Not sure if it still is, or if they just call it DSG 
now as well. But Tiptronic isn't it....

I never studied the DSG principles, but 
http://en.wikipedia.org/wiki/Direct-Shift_Gearbox gives a nice explanation. BTW 
Audi calls this gearbox Tip-Tronic


Cheers,

Hans
