Understanding Common Issues with Airmatic Level Links in Mercedes-Benz Vehicles

Mercedes-Benz vehicles are renowned for their luxury, performance, and advanced engineering. One of the standout features in many Mercedes-Benz models is the Airmatic air suspension system. This sophisticated system provides a smooth, comfortable ride by automatically adjusting the vehicle’s suspension to varying road conditions. Central to this system are the Airmatic level links, which play a crucial role in maintaining the correct ride height and balance. However, like any advanced automotive component, they can encounter issues. Here, we’ll explore the common problems associated with Airmatic level links and offer insights into how to address them.

What Are Airmatic Level Links?

Airmatic level links are small, yet vital components that connect the suspension height sensors to the suspension control arms. These links help the Airmatic system monitor and adjust the height of the vehicle. When functioning correctly, they ensure that the vehicle maintains the optimal ride height, enhancing comfort and performance.

Common Issues with Airmatic Level Links

  • Wear and Tear: Over time, Airmatic level links can wear out due to constant movement and exposure to the elements. This wear and tear can lead to looseness or play in the links, resulting in inaccurate height adjustments by the suspension system.

  • Corrosion: Since Airmatic level links are located under the vehicle, they are susceptible to corrosion from water, salt, and road debris. Corroded links can seize or break, compromising the function of the Airmatic system.

  • Sensor Malfunctions: The level links are directly connected to sensors that relay information to the Airmatic control unit. If the sensors become faulty due to damaged level links, the system may not receive accurate data, leading to incorrect adjustments.

  • Physical Damage: Airmatic level links can be damaged by road debris or during off-road driving. Physical damage can result in broken or bent links, which can severely affect the suspension system's ability to maintain proper ride height.

Symptoms of Failing Airmatic Level LinkS

  • Uneven Ride Height: One of the most common signs is an uneven ride height, where one corner of the vehicle sits higher or lower than the others.

  • Warning Lights: The vehicle’s dashboard may display suspension-related warning lights indicating a problem with the Airmatic system.

  • Rough Ride: A noticeable decline in ride comfort, such as increased harshness over bumps, may indicate issues with the suspension components.

  • Unusual Noises: Clunking or rattling noises from the suspension area can be a sign of loose or damaged level links.

Addressing Airmatic Level Link Issues

  • Regular Inspections Regular inspections of the suspension system, including the Airmatic level links, can help identify and address issues before they become severe.

  • Timely Replacement If wear or damage is detected, timely replacement of the Airmatic level links is crucial. Using OEM (Original Equipment Manufacturer) parts ensures compatibility and longevity.

  • Professional Service Given the complexity of the Airmatic system, it is advisable to seek professional service from a specialized auto shop. Experienced technicians can accurately diagnose and repair issues, ensuring the system functions correctly.


Airmatic level links are essential for maintaining the superior ride quality of Mercedes-Benz vehicles.
