One of the reasons that people love to purchase a Mercedes is due to the engineering and smooth ride that an air suspension provides to the driver and occupants. Being superior to mechanical suspension on most cars, an air suspension is normally used on high-end manufactured cars.
Although this suspension system is well engineered and gives the best ride, they will sometimes succumb to issues. In this article, we will discuss expert tips for addressing air suspension leaks in Mercedes, along with other issues you may have with your air suspension system and what to look for if you begin to experience problems.
Causes of Air Suspension Leaks
It is important to cover how to know if you have any air suspension leaks in your Mercedes. First though, we will talk about what are some of the reasons your Mercedes could develop these leaks in the first place. Here are a few reasons why:
- Valve Leaks: One component of your car’s air suspension system are the valves that control the system itself. Valves have rubber o-rings inserted to keep any air from leaking. If these o-rings are compromised and allow the air to escape, you will have yourself a leak. This is also the case if the valve block itself is cracked due to impact or a defect in the product.
- Air Lines: Your entire Mercedes air suspension system counts on air lines to carry the air under pressure throughout the car. If any of these lines become damaged, loose, or break from wear, you will have an air leak.
- Strut Seals: Seals within the air strut system can become old and brittle over time. Due to extreme environments this deterioration will be sped up. Once the seals give way to air pressure a leak will develop.
- Air Compressor Failure: The air pressure in your Mercedes’ air suspension is made by using an onboard air compressor. The compressor adds pressure as needed when individual sensors throughout the system request it. If the air compressor fails however, your Mercedes will fail to have a working air suspension.
Signs of An Air Suspension Issue
Understanding some of the possible causes of why your air suspension system is not working allows us to move forward with what to look for when it happens.
- Warning Light: Your Mercedes will no doubt alert you via a warning light displayed to the driver. Some warnings are specific and mention air suspension issues, while others may only warn you that something on your car is wrong. If you have the latter warning light on your Mercedes, you’ll have to take it in to an experienced Mercedes technician to troubleshoot the warning code.
- Whistling Sound: If you hear a whistling or hissing sound while operating your Mercedes, it is more than likely an air leak and could possibly be the air suspension as the culprit.
- Leaning or Sagging Vehicle: If you notice that your Mercedes is lower at one or more wheels, you could have an air suspension issue. Depending on where in the system the leak is at, it will show in the location of all wheels past the leak. This is due to the air not being able to reach any of the system after the discharged air.
- Rough Ride: The air suspension system in your Mercedes gives you one of the smoothest rides of any vehicles sold. When the air system is compromised by an air leak however, you will notice a significant difference in the smoothness of the car on the road. If you have anything but a smooth ride in your Mercedes, have it checked for any leaks or other issues with the air suspension.

Now that we know what to look for in 
air suspension leaks, the next step is how to address it. The first bit of advice is to make sure you are following your Mercedes’s service and preventative maintenance plan.
