Thanks for those post answers.....Yes I found the sensor unit at the base of the expansion tank. It all seemed connected up ok so I removed it and gave it a wipe and checked the plug for good connection. all appeared ok and the float was moving ok. I decided to remove the expansion tank and give it a clean out just in case the float was a bit gunged up. When reassembled the warning light went out.
However after 80 or so miles that day and restarting the car the light came back on (bugger)

Decided it must be a defective sender unit so I`m awaiting a new one in the post........
