[Warning Light] Service warning lights

[cancunia]

Hi everyone, I'm new to this Forum and just checking on a couple of service related bits.

I've got a 64 plate van 75hp. I've always done my own servicing for many years. 
This year I have only done about 8,500 miles, the service spanner light came up recently and quickly dropped down to 0 miles range. Is the service light also time related as it's exactly a year ago since the last service and now I have a warning Triangle. Also how far past the date do people think is safe after warning triangle, or is it just Citroen scaremongering? 

Thanks in advance

As noted above, the service indicator is linked to time or distance, it's the same on my M59. At 8500 miles, you're well within the official limits, but a lot of owners tend to change oil twice a year so 6000 miles is a good rule of thumb.
