Understanding the layout of the Mercedes-Benz M272 V6 engine is crucial for both routine maintenance and addressing its well-known mechanical vulnerabilities. Introduced in 2004 as a successor to the M112, this engine featured advanced technologies like continuous variable valve timing (VVT) and a dual-stage intake manifold. 1.

The M272 is sensitive to oil quality and level. The parts diagram of the oiling system is critical to understand.
Flip the engine diagram around to the front view, and you’ll see the Timing Chain setup. Unlike the M112 which used a single long chain, the M272 uses three timing chains: Mercedes Benz M272 Engine Parts Diagram
