Sounds to me like your sensor (thermostat) is on its way out and isn't correctly picking up the temperature correctly. There are two sensors to be aware of and both interact with each other from memory, to find a balance/ensure correct reading. If one is damaged.... no big cost, probably around £50 at a main dealer, cheaper if local garage. Also worth noting that thermostat/temp gauges are 'dampened basically for drivers piece of mind so when an engine is at correct temperature, the gauge is usually about half way - it would normally be nearer the top in reality, but customers don't like to 'see' this as they worry too much. So they regulate the view of the actual temp, hence why I think the sensor/thermostat is at fault.
