My break 2.0 HDI threatens to overheat in city traffic (stop and go driving). It starts like this: it always stays at 70 degrees as long as the car gets good wind, but you get in city traffic (stop and go) the temperature indicator starts to rise and goes up to 90 degrees and the indicator stop starts to flash. Cooling water is enough on it and oil is also filled up to Maxi. It can’t lie there, that happened to me last week in Berlin mid (around 15 o’clock). I closed the ventilation nozzles to the right and left towards the window in the middle and put both windows in front and put heating on full pulley and the heat out of the windows blew the temperature indicator so down 10-15 degrees and stop lamp blinked no more. But that’s not a solution in the long run, since it already starts with light city traffic from 70 degrees to 90 degrees. What’s the problem going on?
