Airmatic Suspension Explained: How It Works and Its Components

The Basics of Air Suspension Systems

Air suspension, a type of automotive suspension system, uses air springs instead of conventional steel springs to provide a controlled ride. Its flexibility allows for adjusting ride height and firmness, dynamically adapting to different road conditions and load capacities. This technology supports the vehicle while delivering enhanced ride quality and comfort for passengers.

Mercedes-Benz Airmatic System Components

The Airmatic system developed by Mercedes-Benz comprises key components such as air springs, a compressor, valve blocks, and electronic control units. These elements work together, adapting to driving conditions to maintain a smooth and stable experience. 

Level and Damping Control Switch

Located within the driver's reach, this switch allows a person to select preferred settings, such as raising the vehicle for off-road conditions or lowering it to improve aerodynamics and fuel economy on highways. The ability for air suspension to adjust the damping forces is crucial for customizing the driving experience.

Valve Block Assembly and Rear Axle Distribution Block

The valve block assembly functions as the air traffic controller of the airmatic system, directing air to various struts as needed. Similarly, the rear axle distribution block manages air supply to the back of the vehicle, ensuring even distribution of pressure and balanced handling, especially on curves and corners. 

Benefits and Drawbacks of Airmatic Suspension Systems

Mercedes-Benz Airmatic Benefits & Features

AIRMATIC Air Compressor Failure and Moisture Issues

One of the most prevalent issues with Airmatic systems is air compressor failure, often due to moisture entering the system and corroding internal components. To prevent this, ensure proper sealing and periodically check for signs of moisture:

  • Listen for unusual compressor noises.
  • Look for error messages related to compressor performance.
  • Inspect the compressor's air dryer; replace it if necessary.

Taking these steps can save considerable time and money, avoiding a full compressor replacement down the line.

Leaking Airmatic Strut and Other Air Leakage Problems

Leaks within the Airmatic strut can lead to a compromised air suspension:

  • Symptoms: Noticeable sagging on one corner, the "sinking" of the vehicle overnight.
  • Solution: A comprehensive check for leaks in the system. Replace faulty struts to prevent further damage.

Other air leakage problems could stem from worn seals or cracked air lines, which also need swift rectification to maintain the integrity of the system.

Slow Ride Height Adjustment and Failure to Adjust

If you experience slow ride height adjustments or the system's failure to adjust, it indicates potential issues with the Airmatic suspension:

  • Possible Causes: Clogged valves, leaking air lines, or an overworked compressor.
  • Troubleshooting: Diagnostic tests can pinpoint the exact cause, often resolved by cleaning or replacing the culprit parts.
