broken wire, the expansion tank will have a sensor on it, there will be a few wires coming out of it. Check these are ok.

Yep. Could be the cap, or the wiring to it. I'm sure there would be someway to test it, but I don't know it. Try a friend with the same control lights, doesn't have to be the same car. Just wire the cap in, and slide the plunger up and down and see if the light goes out.

there is NO sensor on the coolant tank. the wire is there but no sensor. and no wires on the cap. is this normal ?

Is there a sensor lower down the bottle. Should be a float type sensor. Not sure if these are used on the later ones, but would imagine so.
