I seem to recall reading that their automatic-manual transmission,
developed many years ago, was scrapped because it was enormous,
overweight...and so complex in number of computers, actuators, etc.
that it was horribly unreliable...and impossible to even consider
having dealer techs attempt troubleshooting and repairs.
I don't recall any mention of dual clutches like the DSG, so perhaps
we're talking different transmissions.
