Mercedes Benz M272 Engine Parts Diagram [new]
The M272 utilizes a sophisticated variable intake manifold to optimize torque across different RPM ranges. Key Components:
Critical timing requires aligning the crankshaft balancer to 40° ATDC (After Top Dead Center) while ensuring the camshaft pulse wheel markings point upward.
A proper diagram of the M272 engine can be divided into several key systems. This is the heart of the M272's famous issues.
You can reference official diagrams and locate exact Mercedes part numbers using your specific VIN.
To help find the exact component or part number you need, tell me: Your vehicle's (e.g., 2007 E350). The specific symptom or trouble code you are experiencing. Mercedes Benz M272 Engine Parts Diagram
On a genuine Mercedes diagram, every part has a and an Index Number (e.g., #130) . The index number corresponds to a table listing the part name and quantity. Cross-reference the index number, not just the picture.
Plastic tracks that keep the timing chain aligned; can become brittle with age.
: It utilizes continuously variable timing for both intake and exhaust, allowing for a 40-degree adjustment to optimize torque.
The upper portion of the M272 engine controls the air-fuel intake and exhaust gas exit. Because the M272 uses dual overhead camshafts (DOHC) with continuous VVT (Variable Valve Timing), this section contains highly precise electronic and mechanical parts. The M272 utilizes a sophisticated variable intake manifold
The plastic lever arm that actuates the tumble flaps inside the intake manifold is notorious for snapping. When it breaks, the flaps get stuck, which robs the engine of low-end torque and triggers a Check Engine Light. Historically, mechanics had to replace the entire intake manifold, but today, upgraded aluminum replacement lever arms are widely available for DIY repair. 2. Crankcase Ventilation System (Oil Separator)
The M272 was built with a 90° V6 angle, aluminum block and cylinder heads, and features continuously variable valve timing (VVT) on both intake and exhaust cams. It was designed to replace the earlier M112 V6.
To ensure you order the exact replacement components from an official parts diagram, follow these industry-standard catalog steps:
When looking for official Mercedes Star Diagnostic (SDS) or EPC (Electronic Parts Catalog) diagrams, use these specific sub-group terms: Engine Housing (Crankcase and Cylinder Heads) Group 05: Valvetrain (Camshafts and Timing Chain) Group 14: Intake Manifold and Air Ducts This is the heart of the M272's famous issues
Includes the updated shaft, chain, guides, and gaskets.
The lever that controls the intake flaps is made of plastic and breaks. The entire intake manifold often requires replacement, though aftermarket aluminum repair kits exist.
: Four solenoids (two per bank) that actuate the adjusters based on ECU signals. Timing Chain & Guides
