Mercedes Benz M272 Engine Parts Diagram ~upd~ Jun 2026

This schematic details the timing synchronization components. It is the most referenced diagram due to notorious early-model wear issues.

If you own a Mercedes from the mid-2000s to the early 2010s—a C-Class, E-Class, or perhaps an SLK—you are likely familiar with the . This 3.5L V6 was the successor to the legendary M112, marking a significant shift in Mercedes engineering. It was the first to introduce the "Twin-Pulse" V6 philosophy, balancing smoothness with aggressive power delivery.

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.

A heavy-duty duplex chain synchronizing the crankshaft, balance shaft, and camshafts.

What (e.g., 2006 E350, 2010 C300) is the engine in? What specific symptom or repair are you currently tackling?

The Mercedes-Benz M272 engine is a 90-degree V6 family known for introducing continuous variable valve timing (VVT) on both intake and exhaust camshafts. This engine architecture features an aluminum block, magnesium intake manifold, and a counter-rotating balance shaft to eliminate vibrations inherent in its 90-degree design.

Deliver pressurized fuel directly into the intake ports.

The timing chain layout on the M272 is complex because it must precisely coordinate the crankshaft, all four camshafts, and the central balance shaft.

The Mercedes-Benz family, produced between 2004 and 2014, was the staple V6 engine for a generation of Mercedes vehicles, including the E350, C350, SLK350, and ML350. While known for excellent power delivery (24V DOHC), it gained notoriety for specific mechanical issues, most famously the premature wear of the balancer shaft gear .
