Hi,
Have you reinstalled the hose that came off the coolant reservoir? Can you take a pic of the hose in question and upload it for me to see?
Also, for some reason, I'm not showing a C220. Is that the correct model? I see a C250. It may be because you are not in the US. Let me know.
Here is a link you may find helpful as well:

Let me know if that helps or if you have other questions.
Take care and God Bless,
Joe
