Unfortunately my information on the C320 is very limited so I will reopen the question for you, now that the information is complete a Mercedes expert should pick it up for you. If they can help they will post back.

Hi, perhaps I can help. Those fault codes are CAN communication codes between the EIS and the ME control unit and between the instrument cluster and the ME control unit. Possible faults are the EIS or the ME control unit. If there are no symptoms associated with these codes they can simply be erased.

Let me know if you have any questions.
