Technical characteristics of the powertrain

The presented engine belongs to the Engines category and represents a modern four-cylinder diesel construction. The use of Diesel fuel allows for a favorable compromise between dynamics and fuel consumption, which is particularly important in daily operation and for higher annual mileages.

The four-cylinder configuration promotes a compact design, facilitating installation in the engine bay and service maintenance. The unit has been designed to operate across a wide range of loads, which translates into stable performance in both urban and extra-urban driving.

Application in the Mercedes W204 C220 CDI

The engine is intended for installation in the Mercedes W204 C220 CDI model, making it a suitable choice when replacing a worn or damaged powertrain. Maintaining structural compatibility with the factory solution facilitates integration with the existing electrical system, fuel system, and engine accessories.

This type of diesel unit performs well in both fleet applications and private vehicles, where predictable operation, flexibility in the mid-RPM range, and reasonable operating costs are valued.

Condition, mileage, and operational potential

The engine is offered in Used condition, meaning it has been previously operated but is still suitable for further use after proper installation and basic service verification. The available mileage information allows for a better assessment of the unit's potential for further operation in a specific vehicle.

Before installation, standard preparatory steps are recommended, such as replacing consumables, checking for leaks, and inspecting accessories, which increases operational safety and reduces the risk of unplanned vehicle downtime.

Selection by OEM numbers and interchangeable numbers

The engine has an assigned OEM part number and a set of interchangeable numbers, which significantly facilitates precise identification and matching to a specific vehicle configuration. Verification of compatibility by numbers is crucial for professional powertrain replacement, especially in the case of different equipment versions and production years.

To better understand the importance of correct component selection based on manufacturer markings, it is worth reading the practical guide on verifying parts by OEM numbers, available in the article Shopping for parts online without risk – 5 ways to verify OEM numbers. This will help reduce the risk of errors when ordering an engine for your Mercedes.

Benefits of using an original Mercedes unit

Using an original engine from the OM651 family in a C-Class ensures consistency with the vehicle's factory characteristics, including the operation of the transmission, fuel injection system, and driver assistance systems. As a result, predictable throttle response, refinement, and performance parameters consistent with the manufacturer's specifications are maintained.
