Expert Tips for Maintaining Your Mercedes S-Class Air Suspension

Have you ever noticed that your Mercedes S-Class has a lower stance than before? The Mercedes S-Class is an exquisite car to ride and handle because of its sophisticated air suspension system. Unlike conventional vehicles with coil springs, the Mercedes S-Class uses an air suspension system that comprises air springs (air struts), an air compressor, and control sensors. This system controls the height of your Mercedes and also cushions the car against the shocks from the road, making the ride very stable.

However, if it does not work as it should, you may experience a bumpy ride, the car may sit unevenly, and you may hear strange noises from the suspension. If you are having air suspension failure in your Mercedes S-Class, then it should not be overlooked. A bad suspension system will compromise handling and safety and may cause expensive damages if not fixed.

Signs of Mercedes S-Class Air Suspension Failure

• Uneven Ride Height: If your car is sitting lower on one side than the other, it may be due to a leak in the air spring or a bad air strut. This can cause problems in terms of handling and comfort of the car.
• Ride Lower Than Usual: Another obvious sign of faulty air suspension is when the car sits lower than it usually does. This occurs when the air springs deflate and can no longer bear the weight of the car as it is supposed to.
• Loud Hissing or Air Leaks: When an air suspension system is leaking, there will be a hissing sound emanating from the suspension parts.

Solving the Mercedes S-Class Air Suspension Issues

• Check the Air Springs for any Leakage: The air springs are known to get compromised in the course of service and may start leaking, leading to either a sagging or an uneven suspension system. One of the signs that indicate the presence of a leak is when a particular corner of the car is lower than the other corners. To check for leaks, one has to apply soapy water and see if bubbles begin to form at the site of the air springs. If a leak is detected, then the damaged air spring needs to be replaced so that the suspension can work properly again.
• Check the Ride Height Sensors: Damaged ride height sensors may cause the suspension to malfunction improperly or turn on warning lights on the dashboard. These sensors aid in maintaining a level ride by sending signals to the control module. If the car is too high or too low, the sensors may be damaged or incorrectly calibrated. Replacing or recalibrating them can solve height adjustment issues.
• Check the Suspension Control Module: The air suspension system is managed by an electronic module that interprets data from sensors. Flaws and bugs in the software of this module can result in unstable suspension patterns. It is possible to run a diagnostic scan in order to check for codes that are associated with the module. If needed, the module may have to be reprogrammed or replaced completely.
• Check the Air Lines and Valves: Most air lines and valves can be disconnected, and if they are disconnected, there will be no airflow to the suspension components, causing uneven or stiff rides. Another cause of pressure loss is leakage through valves. Check the airlines and ensure that there are no cracked or disconnected sections; if any are found, replace them. Proper sealing of the air system will go a long way in maintaining the suspension system without any hitches.
