The abs instrument light doesn't light up on the dashboard before starting the engine however hdc and traction control come on and off as they should and the abs all works as it should.

I'm assuming it's just a bulb how do I gain access to the bulb?

D2 dash bulbs were discussed on here a short while ago.

Cheers

The warnings are not bulbs but LEDs, i've never seen one failed but that doesnt mean it's not possible, you have to undo the screws from the bottom of the binnacle, push it backwards to unhook it from the clips to remove it then unplug the instrument pack and remove the cover, maybe it's black tape in front of the warniong cos if it stays on alone it's more likely a circuit fault
