Technical characteristics of the N57D30A engine

The presented unit belongs to the Engines category and is intended for BMW 3 Series E90/E91 LCI vehicles in 325d and 330d versions with the N57D30A engine. The inline cylinder layout combined with Diesel fuel injection ensures high torque across a wide rev range, which translates into dynamic acceleration both in the city and on the highway.

This generation of six-cylinder engine is valued for its smooth operation, reduced vibrations, and good throttle response. The architecture used promotes thermal stability and mechanical load resistance, which is important for long-term operation in vehicles with higher weight and power.

Mileage, condition, and application

The unit comes from a vehicle with moderate mileage, which, in the case of a modern BMW diesel, leaves an appropriate margin of operational potential. Used condition means that the engine was previously installed in a vehicle but is still suitable for further operation after proper installation and service maintenance.

The N57D30A engine is the right choice in situations such as:

• comprehensive repair after a failure of the existing power unit,
• professional car restoration after a collision with front-end damage,
• car modernization project while maintaining the original BMW specification.

Thanks to maintaining compatibility with the factory configuration of E90/E91 LCI 325d and 330d models, the installation can be carried out in an orderly manner, using standard mounting points and factory accessory architecture.
