Resetting the maintenance reminder on the Audi A6 C7 can only be done using a diagnostic cable, for example, VAG-COM hex can 20.4.
Resetting the oil change warning can be reset WITHOUT a diagnostic cable, in the CAR System settings menu - Service and Control - Maintenance frequency - Reset the periodicity. (oil)

Changing the periods (mileage and time) of service and oil change reminders:

SIA: maximum value of time to service - number of days before oil change (oil service), 365 days by default, left unchanged
FIX: max. distance until next mileage-related inspection - mileage before service, which cannot be reset without a cable, by default 30000km, I set 50000km
FIX: maximum time until next time-dependent inspection - the number of days before service that cannot be reset without a cable, by default 730 days, I set 1500 days.
