The temperature gauge will get up to 90 in a short time but then its where the weirdness begins. The needle will then slowly climb up to as shown in in this pic:-
Its also not speed dependant as if your doing 20 or 60 makes no difference on it climbing. It will drop to two segments above the 90 and sometimes to 90 be then slowly creeps back up and down. I've had a coolant flush/change and the garage say the thermostat checked out ok. A temp sensor changed at the same time. Driving it this morning its still doing it and next will check for oil in the plug tubes as when using boost on a dual carriageway it spluttered and the check engine light started flashing. The rocker cover has leaked oil into the plug tubes in the past.
One other thing is the engine fans will come on if the engine is warm and the key removed every time. If you restart the engine the fans then cut off again until you remove the key. Fans can at time run for 3 mins full speed. At a drive thru i did feel and hear the fans kick in and the temps gauge drop fast to 90 but then did its slow climb again
