Air Suspension Parts BMW

Product Description

Air suspension systems offer a blend of comfort, adaptability, and performance, and are used in many luxury vehicles, including some BMW models. These systems allow the driver to adjust the vehicle's ride height and firmness, providing a smooth ride and improved handling. Below are the key components of an air suspension system in a BMW:

Key Components of BMW Air Suspension

1. Air Springs (Air Struts):

   • Front and Rear Air Springs: Replace traditional coil springs with airbags that inflate or deflate to adjust the ride height and stiffness. The air springs are typically integrated with the struts in many BMW models.
   • Bellows: These are the actual air-filled components that expand or contract to change the suspension height.

2. Air Compressor:

   • A motorized pump that generates the compressed air needed to inflate the air springs. It maintains the air pressure in the system and adjusts it as needed based on driving conditions or user inputs.
   • Compressor Dryer: Prevents moisture from entering the system, which could damage components or cause freezing in cold temperatures.

3. Air Lines:

   • These are the tubes that connect the air compressor to the air springs, allowing the air to flow and adjust the suspension.
   • Fittings: Connect the air lines to the air springs, compressor, and other components, ensuring an airtight seal.

4. Valve Block (Solenoid Valve Unit):

   • Controls the distribution of air to the different air springs. It opens and closes the air pathways to adjust each corner of the vehicle independently, providing precise control over the ride height and balance.

5. Height Sensors:

   • Mounted at various points on the vehicle, these sensors monitor the ride height and send data to the control unit. The system uses this information to adjust the air springs to maintain the desired height.

6. Control Unit (ECU):

   • The brain of the air suspension system, it processes data from the height sensors, driver inputs, and other systems to control the air compressor, valve block, and other components.
   • Drive Mode Settings: In BMWs, this control unit may also integrate with the vehicle's driving modes (e.g., Comfort, Sport), adjusting the suspension settings accordingly.

7. Pressure Sensors:

   • These monitor the air pressure in the air springs and lines, ensuring the system maintains the correct pressure for the desired ride height and firmness.

8. Reservoir (Air Tank):

   • Stores compressed air, allowing the system to quickly adjust the suspension without needing to wait for the compressor to generate more air.

9. Shock Absorbers (Dampers):

   • Even in air suspension systems, shock absorbers are used to control the movement of the air springs and reduce bouncing. In some BMW models, these may be adaptive dampers that adjust based on the driving mode or road conditions.

10. Diagnostic Module:

    • An onboard diagnostic system that monitors the air suspension components and alerts the driver of any issues, such as leaks or failures in the system.

Common BMW Models with Air Suspension

• BMW 7 Series: Known for its luxury features, the 7 Series often comes with an air suspension system for enhanced ride comfort.
• BMW X5 and X7: These SUVs often feature air suspension to improve off-road capability and on-road comfort, with the ability to raise or lower the vehicle as needed.
• BMW 5 Series (Touring models): Some versions, especially wagons, may come equipped with air suspension for load-leveling and improved handling.unique auto spares,
