Product Description


The Mercedes-Benz S-Class has always been the flagship of the Stuttgart automobile manufacturer. In the S-Class C217/A217 RWD series, which rolled off the assembly line in 2014, the high level of driving comfort is primarily due to the standard built-in air suspension and the extra length. The Aerosus Air Spring offered here is installed on the front axle on the left. The Air spring is compatible with all S-Class C217/A217 RWD AIRMATIC models that only have rear-wheel drive. For vehicles with 4Matic (all-wheel drive), we offer separate springs in our shop.

How does the Suspension of the Mercedes S-Class C217/A217 RWD work?

Mercedes-Benz models fitted with an air suspension system are designated as Airmatic. The installed air springs have ADS (Adaptive Damping System) and solenoid valves. Their task is to make the damping harder or softer by diverting the oil through the ADS solenoid valve. Thanks to various sensors, the control unit automatically adapts the suspension set to the driving modes (Sport, Comfort), road conditions, and speed. For example, an initially soft suspension becomes firmer at higher speeds and thus provides significantly more driving stability.

Air-Spring Leakage or Level Control Failed - Reasons for a Defect

The front of your Mercedes lowers unilaterally or stays crooked? As with many other car parts, air springs wear out, so they need to be replaced over the years. The first signs of a problem are leaks of the shock absorbers due to oil loss as well as a reduced resilience due to compressed air loss. Does the vehicle lowers overnight on the front axle or does the compressor run too long? This may be an indication that the affected suspension parts should be replaced. Even if the shock absorbers leak oil and your car lose oil or you hear loud thumping noises while driving, you should not wait too long before repairing the failed parts.
A cable break, faulty solenoid valve on the valve block, or damaged pressure relief valve on the compressor can also cause the vehicle can no longer be lowered or the damping is significantly harder than usual. Furthermore, residual pressure retaining valves, level, or acceleration sensors may also be defective. In such a case, these parts supply the Airmatic control with improper values, which also makes the air suspension shocks quite hard.

Tips on Changing and Correctly Installing Suspension Parts

In any case, it is advisable to leave the installation or assembly of our spare parts to expert workshop staff.

After installing the front shock absorber, connect the diagnostic device to the vehicle and fill the shock absorbers with compressed air according to the instructions of the vehicle manufacturer and initiate the next steps.
After installing the front air-suspension spring, don't immediately fill the air springs with compressed air, as the axles of the lifted vehicle are hanging down and are therefore outside the control range of the Airmatic control unit. For this reason, after installing the new shock absorber, you should lower the vehicle until the wheels are back in contact with the ground and the distance between the wheel center and the fender is approximately 40 cm. Please don't lower the vehicle completely, as the air spring isn't completely filled with compressed air.

Save Costs with Air Suspension springs by Aerosus

To ensure the tightness of the springs, they undergo a tightness and cycle test, conducted by our team of experts in Germany. This ensures a high degree of safety. Since the air springs of an axle usually wear out equally, we always recommend their replacement in pairs. For this purpose, we offer you a 10% discount on pair purchases. In addition, that saves you the second visit to the garage. Furthermore, when buying online, you benefit from the permanently low prices and the two-year warranty.
