Purpose and Technical Characteristics

The presented air conditioning compressor is an element from the air conditioning compressors and clutches category, dedicated to BMW vehicles with a Diesel engine, including the E87 and E90 series with the M47N2 engine. The compressor's design has been developed to meet the requirements of the BMW air conditioning system, which translates to proper operating pressures, adequate performance, and correct cooperation with engine accessories.

The air conditioning system in diesel-powered cars operates under specific thermal load conditions, which is why a dedicated compressor for Diesel units is crucial for maintaining stable refrigerant temperature and reliable operation of the entire system.

Advantages of Using an Original BMW Compressor

Using an original BMW air conditioning compressor in place of a worn or damaged component provides a number of operational benefits:

• Full compatibility with the BMW air conditioning system – correct operating parameters, matching to hoses, condenser, evaporator, and air conditioning control unit.
• Stable refrigerant pressure – proper compression ensures uniform cabin cooling, even under higher engine loads.
• Optimal cooperation with the accessory drive – appropriately selected gearing and operating characteristics limit excessive load on the accessory belt.
• Reduced vibrations and noise – the compressor's design, adapted to the specifics of the M47N2 unit, contributes to the system's smooth operation.

Condition, Origin, and Practical Application

The BMW air conditioning compressor is a used part from disassembly and is offered as an original used component. Such components are often chosen by users who want to maintain the factory air conditioning performance while optimizing service costs compared to new parts from an authorized dealer.

In practice, installing an original compressor from disassembly allows you to:

• restore full air conditioning functionality after compressor failure, seizure, or a drop in cooling performance,
• maintain compatibility with the factory installation without the need for modifications to hoses or mounting points,
• preserve predictable system behavior under various diesel engine load conditions.

Selection by Numbers and Compatibility

The compressor features an original OEM part number and its associated interchangeable numbers, which facilitates precise identification and selection for a specific vehicle configuration. Before purchasing, it is advisable to compare the markings with the currently installed compressor or verify them using the VIN to ensure full compatibility with your specific BMW E87 or E90 with the M47N2 engine.
