I don't have any error codes.

So my radiator fan doesn't seem to kick when engine temps get abit high, coolant temp and oil temps seems to fluctuate too much

Was driving to work this morning and had my carly plugged in to monitor some temps.

So at standstill traffic after about a 45min drive, i noticed my engine was at 115c and coolant temp was sitting at about 105-110c. Interior fans were also blowing really hot air despite it being on the coldest setting.

When I was driving home I monitored temps again, and coolant didnt go above 100c as it hadnt warmed up yet in the slow part and by the time it had i was on the motorway. I noticed that when I was doing 70mph ish my coolant temps were dropping to under 70c and the engine and oil temps dropped from about 110c to about 90c. I've had this car awhile and I'm quite sure this isnt normal.

I have some ISTA readouts related to the AC which are below.
