The suspension system in your Mercedes S-Class is meant to provide you with a smooth and enjoyable ride. But what happens when your smooth ride becomes a bumpy nightmare? Do you want to know how you can resolve a faulty air suspension system? One of the differences between air suspension and traditional suspension is that it uses air springs to stabilize your car instead of the usual coil springs. These air springs enhance ride comfort and quality by adjusting the height of the vehicle and stabilizing it. When the air suspension starts to fail, you will notice it immediately because your driving experience will not be as smooth as before. Let’s see how you can know when an air suspension is failing and what you should do to fix the problem.
Symptoms of Air Suspension Failure
- Sagging: The most apparent symptom of air suspension failure is when one part of your Mercedes is lower than the other. This sagging suggests there could be a problem with the air spring or strut on that particular side of the car. If the problem is not fixed, then it results in the wearing out of tires on one side and more damage to the suspension system.
- Rough Ride: If you are driving your Mercedes S-Class and find that it has become less comfortable and the roads feel rougher than before, then your vehicle could be suffering from a faulty air suspension system. This system is supposed to help in shock absorption to ensure a smooth ride. So whenever you experience a highly bumpy ride, it means that the air struts or other parts of the air suspension are faulty.
Diagnosis and Repair of Air Suspension Systems
- Fix Air Leaks: One of the problems that can be encountered when diagnosing air suspension failures is that of leakage. These leaks may be in the air springs, air lines, or connection, and must be sealed to prevent the loss of air pressure. To rectify this, you need to determine the root of the problem, which is figuring out the exact spot the leak is happening. This can often be achieved by listening to hissing noises or by applying a mixture of soap and water to the area in order to see bubbles around the area that are leaking. Once the leakage is identified, the part that is leaking should be fixed or, as it is most often the case, replaced. Even though sealants could help to seal up some minor leaks, it is always recommended to replace the faulty components to avoid future leaks and have a long-lasting solution.
- Install New Air Struts: Air springs are used as shock absorbers and help bear the weight of the car. If they become worn out or damaged, the suspension system will not work as expected, and this leads to a bumpy ride. Even though it is sometimes costly to replace an air strut, you still need to have it done to restore the comfort of your Mercedes. When replacing the air struts, make sure you use quality ones.
- Replace Compressor: The air compressor works to ensure that there is good pressure within the air suspension system of the automobile. If it is damaged, it cannot create the necessary pressure, and there will be suspension issues. The most common solution is to replace a faulty compressor with a new one. When selecting a replacement, it is crucial to go for a high-quality compressor that fits your Mercedes S-Class model. This makes sure that the suspension system gives its best performance and also has a long life span.
