Is your Mercedes riding low or struggling to maintain its ride height? This may be a sign that your AirMatic system is having problems. The AirMatic system is found in most Mercedes-Benz models and it delivers the comfortable and adaptable suspension that is expected by Mercedes users. However, like any other auto system, it may malfunction and this will cause some shifts in your car’s performance.

What is the AirMatic System?

The AirMatic system is an advanced air suspension system by Mercedes-Benz that is intended to control and adapt the ride height depending on the current driving scenario. It uses air springs, electronic dampers, and height sensors to offer a smooth and safe ride to the passengers. This system makes your Mercedes move closer to the ground at high speed for better aerodynamics or move higher off the ground when on bumpy grounds. Even though the AirMatic system is very advanced, some of the components can degrade over time and may require replacements. When some of these components begin to go bad, you are likely to experience several problems that may influence your Mercedes’s comfort and safety.

How Can You Tell That Your AirMatic System Has Failed?

• Uneven Ride Height: The first and probably the most evident symptom of a failed AirMatic system is when the ride heights are not consistent. If you find that one of the car’s corners is lower than the other it is high time to check whether the air suspension is faulty. This problem is usually a result of a leakage in one of the air springs that hinders the system from expanding fully.
• Vehicle Sagging Overnight: If you leave your car for the night and return to it in the morning only to discover that it looks as if it has a deflated tire, then this could be a sign that the air springs are leaking. This problem is common in older AirMatic systems where the rubber in the air springs gets worn out or has small holes. These leaks lead to a gradual loss of pressure in the air springs and cause sagging after some time.
• Rough Ride: The AirMatic system is meant for leveling out the irregularities on the road. If you find out that your Mercedes is not hugging the road as it used to before and it feels more rough or bumpy, then it may be time to check the air suspension. This can be attributed to a faulty air compressor or the air springs may have worn out and are unable to achieve the right pressure.
• Warning Light: Modern automobiles have sensors that track the AirMatic system’s functioning. In case of a failure, a light on the dashboard will normally blink and this most of the time is associated with the suspension. If you have this, it is advisable to seek the service of a mechanic as soon as possible to have your car serviced.
• Hissing Sounds from Suspension: If you hear a hissing sound coming from the suspension area then it means that there is air leaking from one of the air springs. This sound is usually more audible when the car is idle or when the suspension is working.
• Compressor Running Frequently: The AirMatic system has an air compressor that is charged with the task of supplying air to the air springs. If the compressor is frequently running or running for long durations, it is an indication that the system is low on pressure. This could be attributed to a leakage in the air springs which forces the compressor to pump more air to keep the system inflated.
