ASSYST Plus question and service intervals




When I go into MSS it asks me for a workshop number and mileage, and miles remaining, etc.
My car has 35,000 miles on it. However, when I go into the ASSYST screen it tells me I have 9400 miles remaining until next B service and does not give me the workshop number like the MSS is looking for.
So does the car do that thing where it "analyzes" driving habits and extends service intervals based on driving conditions? Does this mean my 40,000 mile B-service will actually be due at about 44,400 miles? Splitting hairs, I know, but bear with me.
When I reach a service due marker (as judged by the car, one way or another) does it then give me the workshop number the MSS is looking for to determine what services are due? Does it wait until the actual mileage is reached, or will it start talking to me at xxx miles before reaching service interval?
40k is a big service and I want to start collecting up parts now, just want to be able to plan ahead.
Thanks,
Darel
After a couple of weeks it's now back to miles to go before next service.
