Description

A shock absorber is a device that controls the spring oscillations when the vehicle goes over various road irregularities, so the vehicle's tires remain in contact with the road. In some cases, shock absorbers have a secondary function as a suspension limiter to prevent the suspension from either over-extending and/or over-compressing.

This shock absorber meets the same technical requirements as the original.
Each air spring strut is inspected according to the test report you received.
That's the big difference to the simple replicas!
Only a 100% tested product and the professional installation of it ensures that your vehicle again offers the same ride comfort as with an original spare part.
.
Each pneumatic damper undergoes a quality inspection.
In addition to the appearance and sealing of the air spring, the function is checked to see if the effectiveness of the shock absorber meets the requirements.
For this purpose, each damper is mounted in a test bench and evaluated.

While an air suspension system is more complex, the advantages are clear. The system is comprised of a central air suspension comrpessor as well as air struts within an air bag at each wheel. The air compressor presssurizes the air struts as needed to control the feel. Other components can be seen in the diagram above, all of which are mainly air lines to transfer pressure and driers (filter) to complete the system.

In this guide, we take a look at the Mercedes Adaptive Damping System or ADS. What it is and how to tell if your Mercedes-Benz has it.

Many Mercedes-Benz vehicles are equipped with Airmatic suspension, including E, S, ML, GL, R, and SL classes.

There is a lot of confusion on the Mercedes Adaptive Damping System or ADS.

Sometimes Mercedes ADS is even confused with Active Body Control (ABC) hydraulic suspension.

A few Mercedes vehicles are equipped with (ADS) in addition to Airmatic. Think of ADS as an add-on to the Airmatic. In fact, even though ML, GL, R class sold in the US have air suspension as standard, not all of them have ADS.

What does ADS mean on a Mercedes-Benz?

On vehicles equipped with an Adaptive Damping System in addition to Airmatic (automatic vehicle height adjustment), the driver can select the suspension stiffness (ride quality) at a push of a button. Mercedes with ADS has a button on the center console that allows them to select the stiffness of the suspension. Typically you have three settings.

Sport - Suspension becomes very stiff.

Normal -

Comfort - Very soft suspension, you feel like driving a Lexus.

If your Mercedes does not have ADS, you can not adjust the stiffness of the suspension. The vehicle adjusts the ride height automatically, or you can raise the vehicle. But that does not change the stiffness of the suspension.

Having used an R500 with ADS, my preferred setting is NORMAL. Sport makes you feel every little bump on the road. Simultaneously, the COMFORT setting feels as the car needs new struts and there is too much bouncing. The soft setting is good if you drive in a city with bad roads, but the downside is that it can shorten the life of the airbags. In Comfort ADS settings, the suspension airbags move up and down the most.

How can I determine if my Mercedes has ADS?

There are two straightforward ways to determine if your Mercedes-Benz has ADS.

First, you have a button on the dashboard to adjust the ride quality. The button shows a shock and has the words "SPORT" and "COMF" written.

A car without ADS will not have this button. Cars with airmatic, but no ADS, still have a button to raise the vehicle.
