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?

Hey doctor, I endangered myself and everyone around me driving like a madman doing power slides on a public road, and now my car is overheating!

Doctor: “yeah, don’t do that”.

Highly unlikely unless it got way up into the red. I don’t know what the normal behavior for E39s is, but I would keep an eye on it and consider looking at the typical cooling wear items.

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.

My car did this exact same thing on a 90 degree day, AC on full blast, while I was behind an Audi R8 V10 who gunned it and sped up about 100 yards ahead, I think it was due to me having some odd brand coolant in the car from who I bought it from, and an old, OE radiator that was 19 years old coupled by a soft-failing thermostat. I also **** myself!!!! Thankfully was able to sweve off the gridlock traffic and keep the car rolling so the air could cool it back down.

Now I have a new thermostat, the BMW Blue coolant, all new hoses and sensors and a CSF radiator! No problems since, but have yet to run with my new set up in 90 degree days, guess I will see if things improve this summer.

You are fine.
Clean up your radiator from debris, and if that does not help, change your fan clutch.

Can always check the ACTUAL coolant temperature with the OBC cluster test #7 if next time you want to know for sure. . .

you have a cooling issue, i would look into that asap-likely fan clutch
