Hello together, I have the following problem: If I start in the morning (1-2 degrees) with a heater, then the pointer is in the middle after 15km. Without a heater it is only after 20km of highway & highway. I think this is normal. So now it comes. After 30km I drive down from the highway and into the city (kaum Stop & Go, rather only roll in the 3rd and 4th gear) then the temperature drops by 1 – 1.5 strokes. So I still had something with other vehicles Never. So the vehicle, which the engine is not yet warm and I have to be careful with the accelerator pedal. And that can’t be after 30km and 1-3 degrees outside temperature. Is that also so with you? Can it be that the thermostat is slowly saying goodbye? Car: V70 2.4d 163hp, BJ2007, 120.000km. Thanks already for the answers! Greeting Razzorpl
