My mechanic told me it was the actuator for the air conditioning under the dashboard.
That could be the 'Duo-valve' under the hood as well. Have you taken the car to an independent Benz mechanic, the car is mostly an SLK-320, and he'll know what to check and where the part would be. That's about the best I can do for now. I don't have a recommendation for the mechanic. Good luck!
