Reset service interval V50

Moin moin, just turning off, lit me up: “Do standard maintenance” (or similar wording). The DPF maintenance was done about 6 months ago and 10k km. Has the service forgotten a reset here or is that the memory that the timing belt has to be made soon (car is now almost 10 years old) ? Actually the latter should still have time until May 2016. Someone an idea? Should I reset the counter or until the next regular Ignore maintenance in May?
