My coolant light on a S500 Coupe 1995, goes on and off intermittently! The engine temp is fine, and there are no leaks in the radiator or hoses, as check by a benz dealership when pressurized. Any suggestions would be greatly appreciated.

It's the water/coolant sending unit. It's cheap and easy to replace but buy ONLY the original MB one.
