I'll look for small leaks of coolant again. My only question is... wouldn't I smell the coolant if it's fumes were entering the cabin causing a headache ? I'm assuming the fumes would carry the coolant odor as well... the car is using the green stuff, not the original mercedes coolant. And I can certainly tell the smell of the green coolant
