Sailor is right. If you look back towards the left you will see a fitting directly below that little grill in the middle of the dash. What happens, is the foam connecter piece turns into dust.

The little grill covers an air temp sensor. In order to get a accurate realtime number, Mercedes uses that hose to draw air across the sensor. Otherwise it would be reading the same stagnant air that happens to waft past the sensor.
