Did not know that the dealer wants to do a B service every time if the intervals are extended.
My bimmer has a service reminder that takes cold starts, engine revs, etc into account. Me, I ignore the stupid little lights, do maintenace based on the mileage, and reset the thing whenever it lights up.
