Temperature sensor new XC60

I have bought a new XC60 D4 VEA and am very satisfied with it. However, the outside temperature indicator is a bit strange: If the car is only in the sun for a short time, the indicator shows far too high values (sometimes over 10 degrees too much). The values are not significantly more precise even during the journey. At least in urban traffic the indicator deviates permanently and significantly from the actual temperature. Without solar radiation the indicator seems to work correctly. It’s clear that the body heats up when the car is in the sun, but I don’t know such strong deviations from my previous cars. At least the display normalized a few minutes after the start of the journey also in stop-and-go traffic in the city. At the XC60, on the other hand, the display increases by a further 1-2 degrees after the start of the journey. What are your experiences?
