Hi Folks, yesterday i got a strange fault on my 991. I drove for approx 2 minutes on 50 km/h and then the coolant temperature increase from cold to over 120 C° in one second. While i was driving slowly to find a gasstation where i can fill up coolant liquid the temperature decrease in the same way. In one second from hot to normal temperature (around 100 C°). At home i fill up around 1 liter of liquid. So it seems that some leakage is around.

Did that happened to anyone else? Any ideas what happened? Maybe the liquid storage ist broken and the pressure runs away?

You may have had an air pocket that turned into a steam pocket, which is not good.  You need to get the system pressure tested to find out where it is losing coolant.
