But the Euro versions (at least in the past with the TT 3.2 and I 
believe the euro A3, too) have the "Launch Control" feature, which 
avoids the power cut.

Yes, with this car it's far too easy to be less-than-smooth from a 
stop. A smooth take-off can be done, but it takes some effort to 
train the foot and avoid the initial "lurch" (which is OK when you're 
actually trying to get away as quickly as possible). It might be that 
Audi programmed the throttle too aggressively (assuming the throttle 
progression is adjustable via coding) in order to compensate for the 
lack of a true Launch Control. If that's the case, perhaps the 
VAG-Com can enable the choice of a different "map" for throttle 
effect. I've not see that ability noted, and I've studied OBD.org 
site fairly carefully.

Never heard that complaint. But we've not had a cold morning yet--the 
car is kept in a heated garage so never been colder than about 60F 
since we've had it.
