I’m dealing with the exact same issue. My temperature light came on twice yesterday while driving, even though the gauge looked normal. Every time I pull into a shop and shut off the engine, the light disappears, and the mechanics say they can't diagnose it without the light active. It eventually came back on while I was driving again, so I’m headed to a third shop now for a full diagnostic. Did you ever find out what was causing yours?
