E39 temperature gauge over the middle

Hi guys
today while cruising on the highway, my water temperature was below middle and after stucking in city traffic, it got on the middle.
After few minutes i had the opportunity to do some powerslides and the water temperature rises above middle… i s””t myself, turned the car off and on, and the gauge returned to middle.

Has this done any damage and what could have caused this?

Doing some digging will show our stock temp gauge coding is non-linear. Has more of a range that indicates at 12 o clock. You went above that range it appears.

Doctor above knows best :)

Loading the engine to a high degree with little airflow across the radiator will tend to run a little hot.
