Do you plan to buy a Mercedes W211, or do you already own the model? No matter, in both cases you should know details about the vehicles’ main part – suspension. You might wonder why I consider it as the most important, but since the detail determines our comfortable rides, I guess it deserves our attention. Below I’ll share with you detailed information about suspension developments, their types and you will better understand why a pneumatic system is outstanding.
It’s notable that one certain model might have the pneumatic suspension, and the other one doesn’t… Do you know whether you own a W211 airmatic or not? Below you can find a list of automobile models that work on the system. Also, I’ll explain how to check if your “best buddy” works on a pneumatic system. Besides, I’ll introduce you to an amazing device that helps you to adjust automobile level in seconds! Does it sound exciting? Let’s start exploring.
W211 airmatic suspension development
I guess you have researched before getting an automobile. Purchasing a car is not just exciting, but also a time-consuming process. You have to find the model that meets the best on your requirements, budget, hobby, location, etc. I’d say that by choosing a W211 air suspension you’ve made a good decision, especially since it works with the air system. Did you know that Mercedes has started manufacturing models with airmatic suspension since the 2000s?
Another interesting fact about the model is that Mercedes has manufactured it with two different types of air suspension, the standard four corner Airmatic, and the rear air leveling. To find out which airlift suspension model your automobile has, check the shifter console for a button that you can use to manually raise your vehicle’s height. That feature is available only in the four corner Airmatic models.
After reviewing details about the suspension, you’ll better understand why riding is so comfortable with the pneumatic system. So, let’s review how we’ve got the modern airlift suspension. In simple words, the suspension is a system of springs, tires, shock absorbers, tire air, and linkages that combines a vehicle to its wheels. It is the main part of the car which determines the comfort of your ride. It protects any cargo and vehicle itself from damage and wear. The earliest form of suspension was used for carriages in the 18th century and since then continued development over the years and centuries. As a result of the long development, we have got three different systems: Hydro-gas; Hydrolastic; and an Airmatic. Each of them has its’ own specification and differs from each other. In order to better understand the advantage of an air suspension, let’s review all three systems.
Three types of suspension systems
- Hydrolastic – In this system, the liquid functions as a damping medium under high-pressure, and shifting rubber works as a spring. The liquid’s movement is determined by two valves, which are located at right angles to one another. The upper valve is opened upon liquids’ pressure increase. And the lower valve opening the same way, allows the liquid to flow downwards.
- Hydrogas – There are two main parts in the system: a damper unit and an internal spring. They are located at each wheel. The feature was created for amending the previous hydrolastic system in England.
- Airmatic – The system works with the following sequence. Firstly, incoming air passes through the filter, where the dust is filtered. After this, the air passes into the compressor. Here, the air pressure increases up to about 250 MPa from the atmospheric pressure and is sustained in the accumulator tank. The accumulator tank opens when the air pressure increases above 250 MPa.
I know, on the one hand, all the above-mentioned information might seem confusing… To sum up, the advantage of W211 airlift suspension compared to others is that it uses air and shock absorbers as a working fluid. Air springs are located on the front and rare axles, which automatically adjust to the driving conditions, speed and load. Hence, you don’t have to worry if your car is crowded or the road condition is not perfect. You get comfortable rides on both good and bad roads with the Mercedes air suspension.
Which Mercedes models have air suspension besides W211 airmatic?
As you already know Mercedes has started releasing models with air suspension since the 2000s. In the beginning, only C-class models had such system, but later the variety has increased. Nowadays, the following models work on the airmatic system:
- GLE Coupe
- CLS Coupe
- GLS SUV
- S-Class Maybach
Since there are some cases when the same model cars don’t work with the same suspension system, I’ll explain how to check W211 pneumatic suspension. If you see a black “bladder” from the front axle, then it’s airmatic. But in case you see steel springs there, then your car isn’t equipped with the pneumatic suspension system. Besides, there is another way to check the issue, you should look for a button with a car icon and an upwards arrow. A message appears on display showing those details, in case your car is upgraded.
How to change the level of Mercedes W211 airmatic suspension?
Now, since you already know all the needed information about W211 air ride suspension, let me introduce the must-have device for your automobile –Mercedes lowering tool . I’m sure you’ve thought about changing the car level many times, but all the operations cost a lot… You have to visit the service center, waste time and money, but the device solves the issue. It is designed specifically for Mercedes air ride suspension and adjusts car level in seconds! It works via OBD II diagnostic port. For using the tool, you don’t have to cut or solder any wires. You should simply plug in the module at diagnosis. Activation takes only seconds! After attachment, you can choose the desired mode by using the steering wheel or the combination of additional buttons. You can switch between the below-mentioned modes in 10 seconds.
- Factory – By choosing the mode, an automobile level goes back to factory settings. If you change your mind, you can reset it at any time;
- Low – The Low option gives you the possibility to lower your car with -32mm in the front and rear parts.
- Custom – By selecting this feature you can select preferable height upon your wish for the front and rear parts separately (Min -70mm; Max +40mm;)
Using the tool on your W211 air matic suspension, helps you to improve responsiveness, change the look, and get faster acceleration and quick stops. The cool thing is that you can decrease or increase height upon your wish and needs at any time. The module is untraceable, as you can always choose factory mode and set the automobile on the factory height. Hence, there are no drawbacks to refrain from using the kit.
All in all, after reviewing all the details about the suspension system, its development and its differences, we’ve learned what distinguishes the air system from others. I guess now you know why is so comfortable the Mercedes Benz W211 airmatic and how to differentiate pneumatic systems on your automobile. Now you know how to adjust vehicle height in seconds and I’m sure can’t wait to test it on your “best buddy”. So, let’s try and share your feedback. Good luck!
