I have the 3.0 Diesel turbo and the temp gauge is very much only just in the okay range. So on the left you have the blue section. then the | and my temp sits above that and sometimes it goes up to the half way mark if driven hard. Is my thermo up the creak or do I not need to worry and this is normal.
