I am confident it wont have been set to time and date, you basically have to ask for it to be set to T&D it gets set longlife by default.
There is a misconception about these services everybody assumes that because its on long life it wont need doing for at least a year or so many thousand miles.
If you do lots of short journeys and like to put your foot down, then it will shorten the service interval.
In a lot of cases with the GTI, it is cheaper to be on time and date as the long life service costs a bit more and comes round more frequently than T&D.
All this being said it is strongly advised that on turbo powered cars you should get it serviced annually and not wait for 15000 miles to come round.
