Hello, I had a coolant warning (message + warning tone) at my 2018 4S Spyder shortly after I left. I immediately checked the liquid level, which is far below minimum according to the operating instructions. Is this still enough from your point of view to “just refill”? If yes, I would fill up and go to the workshop.Filling level (YouTube) According to the operating instructions, if the supply is empty, air can enter the cooling system and damage the engine. with this small filling height maybe already a topic? I also worry about the rust spots, which are briefly visible in the video. I had not noticed any rust on the car before.
