Replacing Fuel Cap
FYI, I experienced this condition on several different ocassions which was serviced by the dealer. It was initially repaired as a fuel cap problem. On the third attemp it was noted as a purge valve leak and required replacement of a new valve to correct problem. Maybe you should have it diagnosed by a certified benz repair shop if the fuel cap deal does not eliminate the condition and to correct the issue. My 2% on the issue.
