⚙️ How BMW Air Suspension Works
BMW air suspension systems replace traditional springs with air-filled components, allowing the vehicle to automatically adjust ride height and comfort.
Key Components:
- Air suspension compressor
- Rear air suspension airbags (common failure point in BMWs)
- Air struts (front in some models)
- Valve block
- Height sensors
These components work together to maintain:
✔ Ride comfort
✔ Vehicle stability
✔ Proper ride height
