V70 D5 D5244T4 with 12 liters/100km consumption in short-haul operation…

Hello together, I am currently moving a V70 D5244T4 D5 almost exclusively on short distance with morning and evening over 10km each. I notice that this car with 12l/100km consumes extremely much. On cross-country journeys the consumption drops quickly to 6,5l/100km. My experience with other vehicles with the same engine are significantly lower consumption even in short distance operation. Spritmonitor confirms my experience. Have you got a tip on what I could do to convert uchsmindern to work? Thank you and many greetings!
