1998 BMW E39 528i Auto Trans, 170,000 miles, Temperature gauge stays in middle when driving in city, highway, mountains with A/C on. But today after 15 miles of city driving, I stopped in parking lot for 10 minutes, engine running, transmission in Park with A/C on, and the temperature gauge went in red zone (red light came on). I should have turned the car off, but I had a feeling that once I started driving, the temp gauge needle will go to middle and it surely did go back to middle all the 15 miles of city driving back home.
I checked and there are no leaks, coolant reservoir is full, both fans (front and back) of radiator are running (when car in Park with A/C on).
Waterpump, thermostat (cooler temp type), and coolant were replaced about 2 years ago. So, what else can cause the overheating when in Park ??
