Service interval help
I have 17,500 on my 991. the 'service now' warning came on. I called dealer and they said its the 20,000 mi service.
does this make sense? is the service warning 2,500 miles in advance?
or is this related to age? and the service warning comes on IF the car hits certain mileage or certain age?
I tried to read through service interval requirements by age but i dont know how they calculate age.
BTW, they said I can just wait but I also dont want to wait and void the remaining warranty because age tripped the service warning.

You're on the right track. It is both time and distance. The algorithm will also show service due if you are piling the miles on quickly over a short time. It expects you will continue to do so and will warn when you have two weeks to go with the current rate of putting miles on.
The standard time is 365 days and distance is 10K miles.
At the service reset both of these values are reset. So the time is from the most recent service not the "age" of the car.

this is super helpful. previous owner put 16k mi in 3 years. I put 1,500 mi in 3 months. but I wont keep that up for the year

The OP should look at in the vehicle menu in the display, then info and service intervals to see both the remaining time and mileage. I bet it's not 0.
