Are you feeling that your Mercedes is not as high off the ground as it used to be before? Or do you think it is more jiggly than it used to be? If so, you may be confronted with problems in the AirMatic suspension system. The AirMatic system uses air springs along with an electronic compressor to provide safe and variable ride height in Mercedes vehicles. However, like most systems, the AirMatic suspension can encounter troubles. These issues must be addressed by professionals quickly to get your Mercedes ride quality as you expect. Here are the possible reasons for AirMatic issues and how you can fix your Mercedes to have a proper ride.
Possible Reasons for AirMatic System Dysfunction
- Air Leaks: Just like any other rubber product, rubber air springs may sometimes develop leaks due to wear and tear. This causes the air to come out of the system making the ride height to be uneven or making the ride rough. The compressor may also work hard in order to make up for the lost air and this may cause other problems.
- Compressor Failure: The air compressor is the component that actually fills the air spring. If the compressor is faulty the suspension can’t change height effectively to smooth out the ride or keep the car at the right height. Compressor failure may be as a result of mechanical deterioration or increased usage.
- Worn Air Struts: The air struts in the AirMatic system work as both the air spring and shock absorber. These struts are known to degenerate with time and therefore can lead to poor ride comfort, poor handling, and generally poor ride quality.
- Faulty Sensors: AirMatic system uses sensors to determine the height of the car and subsequently adjusts the suspension system of the car. If a sensor fails the system will not operate as intended and may cause the ride height or suspension to be off.
- Electrical Issues: The AirMatic system is fully controlled by electronics, so any problem with the wiring or the control module will cause a problem with the system.
How to Diagnose and Fix AirMatic System Troubles
- Check for Warning Lights: If you observe a suspension warning light on the dashboard then it simply means that there is something wrong with the AirMatic system. It’s possible to use an OBD-II scanner to scan for the codes that would point to the problem in question.
- Inspect for Leaks: Check the air springs for signs of wear, cracks, or leakage by just looking at them. If one side of the car is significantly lower than the other three, this is also a sign of a leak. A mechanic can give the vehicle a good leak test to help identify any leaks that may be present.
- Test the Compressor: If the compressor is always running, or if it is noisy, it is most likely overworked because of a leak or a malfunction. A technician is capable of running a diagnostic check on the compressor to see whether it will require fixing or if it will require replacement.
- Replace Worn Struts or Springs: If the air struts or springs are worn out they will have to be replaced in order to get the suspension back to normal. Replacing the struts may prove to be a complicated affair and so it is recommended that this be done by an expert.
- Reset or Replace Sensors: If the various sensors should fail then this could cause problems or affect the smooth operation of the AirMatic system. Replacing or adjusting these sensors can help with problems with fluctuating ride height.
