The 2014-2017 Mercedes Benz S550 is built with the following suspension components:
2014-2017 Mercedes-Benz S550 Coupe AWD AIRMATIC Struts (x4)- a plastic and rubber bag that is fitted onto a strut that uses air as a cushion instead of a metal coil spring to hold a vehicle off of the ground and off of its wheels. These struts are controlled by the suspension control module, which is also responsible for redistributing air to the struts as a means of weight distribution while cornering. All air springs all go bad at about the same rate. If one is leaking, the others will not be far behind. For a proper repair, all of them need to be replaced at the same time.
2014-2017 Mercedes-Benz S550 Coupe AWD Height Sensors (x4) - a linkage located near each wheel of a vehicle with any electronic suspension that, either mechanically or electronically, constantly measures the height of the vehicle, and reports this information back to the control module so that the computer can identify if changes in height need to be adjusted accordingly. The ride height sensor is a moving part, and like all moving parts, they will eventually wear out.
2014-2017 Mercedes-Benz S550 Coupe AWD Air Lines- tubes that run from an air pump to the AIRMATIC struts, which carry pressurized hydraulic fluid to hydraulic struts in order to adjust the height of the vehicle, respectively.
2014-2017 Mercedes-Benz S550 Coupe AWD Compressor- if your suspension is leaking down, that means the compressor is working overtime and has likely already burned out.
2014-2017 Mercedes-Benz S550 Coupe AWD Dryer- prevents moisture build-up inside of hydraulic suspension parts.
2014-2017 Mercedes-Benz S550 Coupe AWD Suspension Control Module- a computer which is responsible for the operations of the AIRMATIC suspension system and maintaining the vehicles correct ride height.
2014-2017 Mercedes-Benz S550 Coupe AWD O-rings- Although they are the least expensive parts of the AIRMATIC suspension, they are responsible for maintaining the seal where all of the air lines connect. Be sure to replace the O-rings when repairing any air suspension system.
Suspension Failure Signs
There are classic symptoms of a failed or leaking air suspension system in the 2014-2017 Mercedes-Benz S550 Coupe AWD. Early detection of a bad suspension is the key to maintaining the vehicle's overall health. Look for an inability of the S550 to reach and maintain its proper ride height. A sudden height variance between different sides of the S550 is also a red flag. This may look like one sagging end, one inflated end, a squatting appearance, or a shifting lean from side to side. A bad suspension will wear out the air compressor; if the compressor is running too often or has already ceased working then suspension failure is advanced. At this stage, a suspension warning light will illuminate on the dash.
