C180 Coolant warning light

[ernstn]

The coolant warning light is on, although it ocassionally goes off again. The coolant level has been checked and is fine. The colant sensor has been checked by an auto electrician who tried replacing it without success.
Does anyone know what the problem is?

Tried windscreen washer bottle which is okay. I've read that it could be the radiator fan which is the problem.
