Wanna know the secret behind the Mercedes-Benz S Class’s smooth rides and knockout performance?
It’s all in those air suspension struts. But let them go faulty, and rough rides and bottoming out at corners become the norm. Restore the luxury drive with AEROSUS front air suspension struts.
Compatible Models
These AEROSUS air suspension struts work for all Mercedes-Benz S Class W221 AIRMATIC models. These are the cars with an ADS solenoid valve and RWD.
Got a car with ABC suspension or 4Matic (AWD)? Not to worry— we’ve got separate air suspension struts for those models as well.
How Do Your Mercedes-Benz S Class’s Struts Work?
With ADS (Adaptive Damping System), the W221’s air suspension struts work by making the damping harder or softer by sending oil through the ADS solenoid valve. This allows your Mercedes-Benz to optimize the drive based on the terrain and the driving mode you select.
Symptoms of Faulty Air Suspension Struts
Not sure if your struts are faulty? Check for these signs:
• Leaking from your struts
• Car lowers and sags to one corner
• Car rides lower than normal
• Loud thumping noises while driving
• Tires wearing more heavy than normal
• Rough rides
The reasons for defective struts vary. Sometimes it’s wear and tear. Other times, your sensors send incorrect values to your AIRMATIC CONTROL system.
Either way, replace your struts when you notice the above issues. Otherwise, you’ll find problems in your air bags and air compressor. And that leads to more replacements.
Installation Tips
After you replace your struts, lower your Mercedes until your back wheels hit the ground. DO NOT fill your air struts with compressed air or lower your car completely.
If you’re new to car repairs, feel free to send your air suspension struts and car to your local garage. This allows for stress-free maintenance.
