I think it would be well worth a reset (basic setting adaptation) it clears the fuzzy logic as Loucyffer said but it also get the clutch plates to re-learn there bite points and shifting patternn (on the prescribed test drive after) my car is an 05 and has at times decided it doesnt like to shift smoothly like a DSG should, basic settign reset helps alot, also driving around in Manual more will help.
Obviously your car has only covered a relatively small mileage and the VW standard for servicing is 40k miles but it has been suggested that you also get the DSG fluid changed at 4 years, if you think about it the wet clutch in the DSG and the gearbox itself are all swimming around in the same fluid, and that fluid hasnt been changed since the car was new so all the swarf off the gears as it bedded in are still floating around in the fluid, and the DSG box also creates massive heat and shearing forces. So it could be worth a fluid change if the reset doesnt rectify the shifting, especially before going down the expensive mechatronic replacement route.
As Steve mentioned, full VE service history cars that have been serviced to VW spec often see a bit of good will on DSG mech issues if it comes to that.
