Hi all

I’m facing one of the strangest issues I’ve ever seen and need your assistance

My car is 528 2014 for 7 years, I live in a hot climate area.

I noticed when I drive the car for long distance sometimes the temp gauge starts to rise up

I opened the hidden menu to check the oil and coolant temperature

After absorption for more than 1 month I noticed the following

1- oil and coolant temperature are changing according to the outside temperature
2- whenever it’s ABOVE 99F everything seems fine and coolant/oil temp between 208f - 215f
3-whenever outside temp is BELOW 99.5F coolant/oil temp rises up to 240
4-temperature gauge only moves when I’m driving on a highway
5-when temperature rises up if a push the throttle down and give the car an air breeze temperature gauge drop down immediately temporarily
6- no overheating or any other codes
7- all related parts are OEM and most of them are new


Any suggestions??

This is normal behavior since your car have active grill shutter which open and close as needed. Oil temperature of 240F is normal for an N20 engine.
