Mercedes C240 Catalytic Converter Noise

The metallic noise is coming from under the car. Noise is most prominent when the car is stopped or when it is accelerating from a stopped position, but that could be because when driving at speed, the road noise drowns out the clanging sound. The repair shop said it was the honeycomb structure inside the catalytic converter that came loose and is clattering around inside.

On a related note, can anyone tell what that clicking noise is near the front engine compartment near the windshield wiper reservoir?
