I had the same experience last week, also with my '10 S5 (negotiated the map upgrade as part of the deal to buy my wife's '14 Q5 TDI). Spent 3 hours at the dealer the first time, and as with you, was told it was "all done". Having made a screenshot of the version, I then looked and sure enough, same version. Went back in and got the same "we have no idea" that you had. And, as someone else observed, it required the MMI's being updated prior to the map update...all of which is now done but all of which required a second visit (with a loaner this time...I wasn't about to wait around). Maybe it's because of Audi's very high cost of map updating that they have so little experience in doing it correctly...or maybe they're just incompetent.....
