Technical characteristics of the OM647 647.961 unit

The engine belongs to the family of Mercedes diesel units, known for their resistance to high mileage and stable performance in daily use. The five-cylinder design provides a favorable compromise between refinement and service simplicity, while the diesel fuel supply system allows for good torque across a wide rev range.

The unit was factory-adapted to the specifics of the E-Class W211 270 CDI model with 177 HP, ensuring it works perfectly with the factory electronics, drivetrain, and auxiliary equipment. The engine's mileage is relatively low for this generation of diesel, which in practice translates into preserved operational potential and a greater safety margin for further use.

The offered engine is dedicated to the Mercedes-Benz E-Class W211 in the 270 CDI version with 177 HP, meaning it serves as a direct base for replacing the power unit in this specific model variant. Thanks to maintaining structural compatibility with factory solutions, installation proceeds in an orderly manner, without the need for adaptive modifications in the engine bay.

This type of diesel unit performs well both in highway applications and in daily urban use, offering predictable torque characteristics and stable operating parameters. The engine from the Mercedes Engines category is also a beneficial base for workshops specializing in the service of W211 models that are looking for a complete unit for professional replacement.

Benefits of choosing a complete used engine

• shorter vehicle downtime due to the possibility of quickly replacing the entire unit,
• preservation of the factory engine operating characteristics,
• easier diagnostics and service in the future, thanks to compliance with the manufacturer's original solutions.

Ecological and operational aspects

Choosing an original used engine is not only a rational economic decision but also a solution that is beneficial from an environmental point of view. Reusing a functional power unit reduces the demand for the production of new components, thereby reducing the carbon footprint associated with vehicle operation.
