Iâm experiencing some issues with my cars temperature when driving it doesnât hit 90 and Iâm now thinking that my thermostat is stuck open not allowing my car to hit 90 I left my car running to see if the car would hit 90 stationary and it does and sits at 90 and when driving it falls down towards the 70 mark I have opened the expansion tank to release any trapped air and nothing changed also the oil temperature seems to be low Iâm thinking that the car is needing the thermostat replaced to cure the problem any help will be appreciated thanks and the cars a 2000 s4 b5
