My car also has the spanner/service light on, normal for me, it's an annual reminder that my car is due for annual service. I haven't reached the required mileage though (might be 9k-10k miles service interval) maybe the 1 and spanner symbol means annual service is due, anniversary timescale and maybe number 2 and spanner means mileage interval has been reached, service due.
Maybe the numbers aren't related to the service at all and it was that menu that you had on the screen when the service warning lit up. I'll take a look at my car today and see what it displays.
