Intended Use and Compatibility with the M47N2 Unit
The air conditioning compressor for BMW E87 and E90 is designed to work with the M47N2 diesel engine. This means it is properly matched to the characteristics of the diesel unit's operation, including its RPM range, loads, and thermal conditions typical for diesel engines.
Selecting a compressor dedicated to a specific fuel type minimizes the risk of incorrect system pressure, excessive vibrations, or accelerated wear of accessory components. This ensures the air conditioning system maintains stable operating parameters both in city traffic and during longer highway drives.
Technical Characteristics of the Air Conditioning Compressor
As a component in the air conditioning compressors and clutches category, the compressor is responsible for compressing the refrigerant and maintaining the correct pressure in the circuit. A properly selected compressor contributes to:
- effective interior cooling while maintaining the set temperature on the climate control panel,
- uniform system operation without sudden pressure fluctuations or undesirable performance drops,
- optimal engine load, which translates to predictable fuel consumption and driving comfort.
The compressor works with belt-driven accessories, so proper matching to the drivetrain is important for the durability of the belt, pulleys, and other auxiliary components.
Benefits of Using an Original BMW Compressor
Choosing an original BMW air conditioning compressor for E87 and E90 models with the M47N2 engine offers a range of practical benefits for everyday use:
- Factory Fitment – maintaining the original mounting geometry and connections facilitates installation and reduces the risk of system leaks.
- Compatibility with Vehicle Electronics – the compressor's operating parameters are consistent with the design of the climate control units used in these BMW generations.
- Stable Operation in Diesel Engines – the construction is adapted to the characteristics of the diesel unit, promoting uniform crankshaft load.
- Possibility of Using Existing Interchange Numbers – simplifies verification of compatibility with a specific vehicle configuration.
Condition, Verification, and Practical Application
The offered BMW air conditioning compressor is a used part, allowing for an economical restoration of the cabin cooling system's functionality while maintaining the original manufacturer's specifications. This type of solution is particularly beneficial for intensively used vehicles where a reasonable repair cost is important while maintaining correct operating parameters.
Before installation, standard servicing procedures are recommended: checking the entire system for leaks, replacing the receiver-drier, and using the correct amount of compressor oil according to the air conditioning requirements for the specific BMW model. This approach increases the chances of long-term and stable air conditioning system operation after compressor replacement.
