The W220 Mercedes-Benz S Class is still symbolic of the strengths of the luxury Mercedes brand. It is especially well-known for its smoothness and the associated driving comfort. The main reason for this is the air suspension on the front and rear axles, as fitted standard for the first time in this model, and which is connected to the adaptive damper system (ADS). Hence, the ride comfort has been improved.
The brand new Aerosus air-suspension strut for the W220 S-Class, which we offer, is compatible with all models that have air suspension. On the front axle, this includes the years of production from 1998 till 2006, provided that the vehicles were delivered with rear-wheel drive. Vehicles with four-wheel drive, which are named 4Matic by Mercedes, require different air-suspension struts. We also offer the strut for the 4Matic.
Owners of W220 S-Class cars pay special attention to comfort and luxury. These values also represent the vehicle to the outside. Such attributes can be demonstrated by the original Aerosus air-suspension struts. The air suspension shocks undergo continuous quality inspection by our team of experts in Germany. With this quality standard, we ensure the Aerosus air-suspension struts for the W220 Mercedes-Benz with a long service life and a precise fit are practically identical to the original Mercedes-Benz parts. The tightness of the air suspension shocks is ensured by an additional leak and cycle test.
The Construction of the Air Suspension Strut
The W220 S-Class has an air-suspension strut, which consists of the actual air spring and the shock absorber. In addition, there is the residual pressure retaining valve, which is installed in the strut. This ensures that the vehicle is exactly balanced even when the wheels are at a standstill. These two components together form the finished air-suspension strut.
If your air-suspension strut only has a broken air-spring bellow and the shock absorber is still in order, we can offer you our original Aerosus front air-spring bellow for S-Class W220 at OEM quality. The air-spring bellow can be replaced independently of the shock absorber. In this way you can save costs. These can be bought separately in our shop. At Mercedes, you can’t get the air-spring bellow separately but must purchase a costly, complete air-suspension strut.
Early Detection of Defects in the Air Suspension
Air suspension struts are also exposed to wear and must be replaced after some time. A broken air-suspension strut can be recognised if one side of the vehicle drops after a few hours of standstill. Increased compressor activity while driving also indicates a problem with an air-suspension strut. Other symptoms include thumping noises or a gradual loss of oil. These signs can be easily recognised by non-specialists as well. It is particularly important to remedy these leaks quickly. The compressor works continuously, trying to compensate for the loss of air, and can thereby overheat and even suffer water damage. This allows the problem to cause greater damage, which could otherwise be halted at the start.
A widespread malfunction is evident in the S-class. The vehicle can no longer be lowered or the damping is suddenly too hard. The causes of this problem are numerous. Both a faulty solenoid valve on the valve block and a cable break may be responsible. If this problem occurs, then it’s urgently necessary to inspect the Airmatic system.
During operation, the components of the air suspension system are exposed to the same loads. Therefore, we recommend the pair-wise change of parts. You benefit from our discount of 10 percent on a pair purchase. All our Aerosus air-suspension struts are offered with a two-year warranty. In addition, you’ll receive a 30-day money-back guarantee for your purchase. That allows you to be completely carefree when buying the car parts.
