Mercedes is known for producing luxury vehicles and with ultimate performance of its systems. Mercedes introduced the AIRMATIC system suspension to replace the traditional coil spring previously used In their vehicles. AIRMATIC suspension, just like its name suggests, employs bags made of rubber and polyurethane filled with air. The system features an electronic level control, adaptive damping on all four corners, and a compressor that pumps air into the bags.
The system allows the car to remain comfortable regardless of the road conditions. The system absorbs shock by adding or removing air as the air springs move up and down. The suspension is also equipped with a button that enables the driver to switch between driving modes (Comfort or Sport mode). The introduction of the AIRMATIC system suspension didn’t phase out the traditional coil spring but was limited to some models.
Mercedes designed the AIRMATIC system with comfort and stability in mind. The suspension was designed to absorb shock and maintain utmost comfort in the cabin regardless of potholes and bumps the vehicle encounters. Like all working parts, time and constant use are bound to wear out the system. The following are symptoms to look out for to identify a failing or defective AIRMATIC system.
One of the first and most obvious signs of warning is a flashing alert on your dashboard: Air Suspension Failure. Other common signs to look out for include:
One of the main purposes of your Mercedes AIRMATIC system is to reduce the effect of uneven roads to ensure smoother rides. Experiencing bumpier rides than normal is a sign of a defective suspension system, and it could be a failure of the fuses in the system.
You can also get an idea of the health of the suspension system using the bounce test.Push your entire weight down on your car’s hood and release it. If the car bounces more than three times after releasing your weight, then it’s probably time to get your suspension system checked by a professional.
You might also notice that the whole car is lower than usual. More often than not, it’s caused by the AIRMATIC’s compressor failure. The AIRMATIC’s compressor regulates the system pressure, raising or lowering the car as required. Malfunctions of the compressor, such as motor burnout, are what cause the vehicle to sit low. You might also notice loud, unfamiliar sounds coming from the compressor whenever you put heavy loads in your vehicle. A noisy air compressor is a tell-tale sign of defect.
A faulty strut in the AIRMATIC system can often cause your car to sit awkwardly. In cases like this, one side of the vehicle will look lower than other sides, and it would look like the car is leaning towards that particular side. This tilting could mean a failure of one or more air struts, as a leaky air strut is a common problem of the Mercedes AIRMATIC suspension. While a leaking air strut is an easy fix, it is dangerous to drive with one. It is strongly advised to let a specialist handle the problem as soon as possible.
