I have a petrol. Very easy on that. On a diesel I heard it's a pain. Good luck and keep us posted.

Could be the thermostat or temperature sensor

Hi Neil!
 
A few questions to ask first....
 
Is your coolant level dropping? Ie are you having to top it up?
 
Does the car get hot when sitting in traffic? Or only when going up inclines?
 
Does the temperature gauge generally sit steady once warned up, or does it fluctuate up and down?
 
When starting the car from cold, do you hear any sloshing/bubbling noises?
