Sorry VvrooomM, I don't understand what you just said.
As you say, the actual service is as indicated on the dash. When you have an oil service carried out as per schedule, the dash will then change to say that an Inspection is due next. This would mean Oil Service, Insp1, Oil Service, Insp2, recurring; would it not? You sound from your post like you are agreeing with my theory, not disagreeing...
Oil, roughly every 15,000 miles or 2 years
Inspection 1, roughly a further 15,000 miles or another 2 years (4 year point)
Oil, roughly a further 15,000 miles or another 2 years (6 year point)
Inspection 2, roughly a further 15,000 miles or another 2 years (8 year point)
Brake fluid is time limited and is carried out every 2 years regardless of mileage.
