Hello again, when I turn off the engine the level on the gauge go to the high temperature, when I turn on the engine again it goes back to normal. What is happened here? Is it a serious problem?

If you are not having any other problem this can be normal. Have you installed a new battery lately? Can you please shoot a quick video with your phone so we can see the gauge to be sure, that would be great. You can upload it here with your response.
