Servicing the Cam Chain Drive System on 2005 - 2012 Mercedes 272 & 273 engines could result in engine damage if the left intake cam is not properly held in place.  Because of the unusual timing degrees used in these engines, the cam could move out of time when the chain is removed if not secured.  The original timing chain has no timing marks.  Cam movement during re-assembly could cause engine damage.  The cam lock bolts to the head holding the cam in position during service operations.
