UGH this does not seem to be isolated. I feel for you, but at least you get an A6 to use (and an Avant which will be a different experience).

You gotta start wondering if this whole business with "not taking any more orders for ultras with S-tronic boxes" is related to this. If there is something amiss with that gearbox - whether it is design related or a manufacturing process wobbler - they will need time to diagnose root cause and rectify before churning out more boxes. And if I were in Audi Quality Control at the assembly line I'd also be pushing already manufactured boxes that are waiting to be fitted to vehicles back for additional checks. It all results in reduced vehicle manufacturing output and delivery delays.
