The car has had a new thermostat, pressure switch, radiator temperature switch, water pump and a new coolant expansion bottle. But the temperature warning light still comes on now and again. Oil levels are good and clean just been serviced.
The temperature warning light came on at my local garage and when the temperature was checked it was actually 65 degrees so we changed the expansion bottle but as i say it come on now and again.

Hi and thanks for using 2CarPros.

If the light is coming on but the engine isn't actually overheating, chances are it is either a bad coolant temperature sensor or a short to power. I have to apologize. I don't have the specific technical information on this vehicle because it isn't offered in the US. So, my manuals don't have it. However, you mentioned the expansion bottle was replaced the last time you had it checked. I have to be honest, I have never see a temperature sensor located in the expansion bottle. Why was that done?

Take a look through these links.

Let me know if any of the other symptoms mirror what your car does. Also, a bad sensor can turn the light on if it is shorted. That isn't mentioned in the link.

Let me know if this helps or if you have other questions.
