I have the same exact car with the same problem. Bought it new and haven't really driven it much. I guess from setting for months the radiator started leaking so I had it replaced. After a few week on neat in the car? Live in FL so it hasn't been a problem until this year? Any sggestions from anyone?
I have the same car on 1999 Mercedes-Benz CL600
