Fixed service interval is 1 year or 10,000 miles - whichever comes first.
Variable service interval is 2 years or 20,000 miles (reducing according to driving style & conditions) - whichever comes first.
Sounds like the dealer put your car onto fixed service intervals and the year is up...
BTW idiots at local Skoda dealer coded the instruments wrong when they serviced my wife's car last month, put it on a 36 day service interval instead of a 360 day service interval. Sorted with VAG-COM in 5 minutes!
