V70 D4 VEA automatic – start/stop and engine jerking after software update 2017

Of course, I also got a software update during the inspection in August 2017. First of all, I didn’t notice anything, but since it’s cold, I have a lot of motor rucksacks in certain situations. It’s almost always reproducible, for example, if I drive in the city at a speed of 50km/h with (distance) tempomat, the car slows down to 35-40km/h and then slowly accelerates again. That is, if it accelerates very little between 35 and 50km/h, e In addition, the start/stop system seems to have been changed. If I remember correctly, it was deactivated earlier at low (and high) outdoor temperatures. Now we had -5°C the other morning, I drove a short bit and although the engine temperature indicator indicated only a small warming – it was still far away from the middle position, the engine was exhibited at the stop at the traffic light. I suspect that Volvo too was something about the nitric oxide sink. has been changed with the software update without commenting on this. Has any of you had similar experiences? Does anyone know what might have been changed in the update? Greetings, Matthias.
