Hi everyone, I got this weird rough knocking/tapping noise (from engine assume) for a few seconds after starting up my one-year old 2010 C300 (W204 I guess). It happens after it has been running for a while and is re-started when not fully cool.

Checking, discoloration, or small pieces missing are all signs worth paying attention to.
