Just an idea to try that, pinched from Corsa C forum. will onlt allow you to read the codes, not clear them. i used to have all the gear for reading vx codes and such but i think i left it in the car when the insurers took it to be scrapped.
and that light is not "definitely emissions" it will come on for electrical faults, ECU faults and low fuel pressure, misfires, timing faults. All experienced by myself with the corresponding fault codes to go with them.
