Hello, my V70 D4 GT has barely 10000 km on the hump and is incontinent. For the first time the problem was noticeable on Christmas Eve. I was late and I still had to pick up my Brunder. Therefore, I ripped down the 180 km from my place of residence in Stuttgart in 80 minutes. The cruise control was wherever possible at 200 km/h. When I wanted to leave Stuttgart again, the message “cooling medium level” appeared to stop low safely. In the dark was n As the temperature was inconspicuous, I agreed with Volvo Assistance to cover the rest of the route leisurely and control the coolant level the next day. In cold condition, it was well below “min”. Volvo Assistance therefore sent a friendly person from the ADAC. He filled the tank with water and carried out a pressure test after a test drive. It was just as inconspicuous as the visual inspection of leaks. After the holidays I then drove to my Volvo dealer. He could not notice any leaks on the stage. Of course I also checked the parking space. There was no cooling liquid to find. 600 km after the first occurrence of the problem, the coolant stand is in cold condition again under “min”. The vehicle has dropped this distance somewhat to equal parts in short distance operation and on the highway. I realize that the passage to the handle Nevertheless, I would like to show up there as well informed as possible. That is why I am interested in your assessment. Two observations could be helpful. At the beginning of November the vehicle had a marten damage. At the same time an exhaust gas temperature sensor had to be changed. The dealer could not detect any further damage. And, as I said, a liquid loss was not detectable since then. In the weeks before Christmas, especially as long as the engine was still It can be a clue to air in the system as far as I know.
