1. Faulty air compressor. The air compressor supplies pressurized air to the air springs. If it is faulty, it cannot generate enough pressure to keep the air springs inflated.
2. Leaking air springs. If there is a leak in the air springs, it can cause them to deflate. This will lower the vehicle and cause the Airmatic system to malfunction.
3. Faulty air suspension control unit (ECU). The ECU controls the Airmatic system. If it is faulty, it can send incorrect signals to the other components of the system. This can cause them to malfunction.
4. Electrical issues. The Airmatic system also relies on electrical components, such as sensors, switches, and wiring. Any problems with these components can cause the Airmatic system to malfunction.
5. Mechanical issues. There are also several mechanical components in the Airmatic system, such as valves and solenoids. Any issues with these components can also cause the Airmatic system to malfunction.

* Check the electrical components. Check all the electrical components for any signs of damage, such as frayed wires, loose connections, and blown fuses.
* Check the mechanical components. Check all the mechanical components of the Airmatic system for any signs of damage, such as leaks, and misaligned components.
If you are unable to identify the source of the problem, it is best to take your Mercedes to a qualified mechanic. They will be able to diagnose and fix the problem quickly and safely.
