Hi 190dee,

I just phoned with a Mercedes dealership, drove by, and got a Owner Manuel free! because it´s in english and not German Thanx for your offer though.

G-Benz: turns out that you were right ! It is the Coolant level warning (I still think it looks like an motor from afar

Obviously in the Morning when it was cooler not much coolant was need, then on the way home when it was warmer more collant was pulled out of the resevoir and the light went on. I´ll add abit and that´s that. At least I now know the the Coolant sensor is working properly

Thanx for your help everyone ...

Later ... Tim
