I was driving a long downhill 5 mile section of freeway at 55 MPH and an outside temp of 59 deg. f and an oil temp of 226 deg. A week later, coming back up the same section of freeway in the other direction at 60 MPH and an outside temp of 65 deg. the oil was sitting at 108 deg. Uphill, downhill, load and outside temp didn't seem to have any logical effect on the oil temp. I know it should have but something was strange. Software management? This was in a 2021 Tiguan.
