Proper spark and timing control are managed by a series of sensors and individual ignition coils.
The M272 uses plastic triangular actuator levers on the front of the intake manifold to control internal air flaps. The plastic brittle-hardens from engine heat and snaps.
Circulates coolant through the block and radiator.
Features internal swirl flaps to alter airflow; the external plastic actuator triangles frequently break.

Which you are planning to work on (e.g., timing chain, intake manifold, oil leaks).
Plastic triangular lever on the front of the manifold (prone to snapping).
Plastic/nylon guide rails keep the chain aligned, while a hydraulic chain tensioner applies constant pressure to prevent chain slack.
Positioned in the "V" of the block. It spins at crankshaft speed in the opposite direction to counteract vibrations. Note: 2005–2007 models are notorious for soft gears on this shaft. Proper spark and timing control are managed by
To maintain optimal operating temperature and supply hydraulic pressure to the camshaft adjusters, the M272 features an integrated high-flow oil and water system. Key Diagram Components:
The Mercedes-Benz M272 engine is a 60-degree V6 gasoline engine produced from 2004 to 2011. It replaced the M112 V6 and became a workhorse across a vast range of models, including the C-Class (W204), E-Class (W211), SLK (R171), ML-Class (W164), and even the Chrysler Crossfire. While beloved for its smooth power delivery and dual overhead camshafts (DOHC), the M272 is also infamous for certain mechanical flaws.
You can reference official diagrams and locate exact Mercedes part numbers using your specific VIN.
Two intake and two exhaust camshafts. They feature hydroformed hollow construction to save weight. Circulates coolant through the block and radiator
