Temperature gauge drops while accelerating/driving
c180d w204 2014
I recently realized that my car drops in temperature while accelerating hard, or if i driving 165 or above km/h on the motorway for a longer period of time.
It goes from normal to dropping to 75-80. When letting go of the gas, its swings a little and then returns to normal operating temperatures.
Im not sure if this is normal or what, I don't remember it doing this last year?
not sure if it has meaning, but the car is tuned from 120hp to 210
