CAN YOU DRIVE WITH BAD PNEUMATIC SUSPENSION?

Owning a car is so exciting, enjoying rides with your “best buddy” and spending time pleasantly. Your rides must be much comfortable if your Mercedes has a pneumatic suspension. It’s a well-known fact that vehicles working on airmatic suspension system offer enjoyable rides, as the system adapts accordingly to the surface of a road. Nonetheless, of the systems’ reliability, things can still go wrong.

There are cases when airlift suspension is out of order. On the one hand, the damage can’t be visible, but it might define further issues. For that reason, if your car has an air suspension, you should definitely know issues related to the system, how to identify signs of damage for avoiding further complications. Besides all the needed information, I’ll also introduce you an amazing lowering tool, that totally changes your experience.

I guess it sounds interesting, so let’s start our journey in exploring all the needed information about the suspension system!

The pneumatic suspension system and related issues

Owning a car is enjoyable until we face some technical issues. It’s the same attitude almost for any car-owner. Dealing with vehicle-related problems isn’t what we expect while purchasing a car. But no matter our expectations, sometimes even high-quality and reliable parts are out of order.

“Knowledge is power”, so let’s learn some useful information about our “best buddies”, for avoiding any bad experiences. I know it might sound boring to talk about parts of an automobile, but Air matic suspension is an exception. It’s the part about which you should know all details. So, let me describe what determines the importance of the tool.

Description of a suspension system

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 automobile itself from damage and wears.

The earliest form of a suspension in the 18th century was used for carriages and since then it has 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.

How does the airmatic suspension system work?

How to use airmatic suspension?

So, what distinguishes the airmatic suspension from others? In this system, air springs are located on the front and rare axles, and it works with the following sequence.

  1. Firstly, incoming air passes through the filter, where the dust is filtered. After this, the air passes into the compressor.
  2. Here, the air pressure increases up to about 250 MPa from the atmospheric pressure and is sustained in the accumulator tank.
  3. The accumulator tank opens when the air pressure increases above 250 MPa.

In simple words, it uses air and shock absorbers as a working fluid. The air suspension system isolates the vehicle’s body from the vibration derived from the road inconsistency.

Issues related to the air suspension

Now we know how sophisticated and perfected is the suspension system, but there are still some issues related to the system. I’d emphasize two main issues, compressor malfunctioning, and leaking air.

As we already know, the airbags are filled with air through the air compressor. Hence, if the air compressor stops working, then bags won’t fill with air, and that might affect other critical parts. As a result of the compressor malfunctioning, you might mention the change in a vehicle height, it must be lowered and hear strange noises related to the compressor issues.

And the second main issue is an air leaking. Since the pneumatic suspension, uses air and shock absorber as a working fluid, it is typical for air leaks to occur when there’s some technical problem. There are several components of an airmatic suspension that can be the source of leaking air.

For that reason, issues related to suspension should be addressed to a professional technician. Costs related to air suspension system can be quite high.

Signs of a bad pneumatic suspension system

I assume now you have some knowledge about the part, which determines your comfortable rides. In order to keep the enjoyable experience, let’s review signs of a bad airlift suspension. Knowing those details avoids further complications. So let’s review signs which we should alert.

Strange noises while driving

Hearing strange, unusual noises while driving is the most noticeable sign if something goes wrong. Such noises might be a sign of a problem with the compressor’s motor or fan. If you continue driving, as usual, no matter the voice, the compressor might fail. As a result of the compressor failure, airmatic suspension will be disabled.

Lowered automobile

Another noticeable sign is a lowered vehicle. If you notice that your automobile is lowered than normally while in motion, that might be a sign of an air ride suspension issue. As you already know the system works by using pressurized air from the compressor. Hence, if the compressor is out of order, it can’t inflate the airbags. As a result of the issue, we get lowered automobile.

Disabled compressor

Most suspensions are auto-regulated and the compressor automatically is enabled or disabled as needed. But, in case the compressor doesn’t turn on when required, it indicates it’s malfunctioning.

All the above-mentioned signs are the most important and if you face any of them, you should alert and address them to a specialist.

Importance of Mercedes lowering pneumatic suspension tool

Pneumatic suspension for Mercedes

I know reading all the technical details about the suspension system might be boring, but let me introduce you to the amazing lowering tool. By using the tool, you will explore how cool it is to have an automobile with an air matic suspension system. You can change the height of a car at any time in seconds upon your wish!

All about the Mercedes lowering tool

The Mercedes lowering tool is designed specifically for the airmatic system and works via OBD II diagnostic port. Don’t be afraid if you don’t have any knowledge of a vehicle. It’s easily attached by using the DIY manual and doesn’t require cutting or soldering wires. For using the feature, you should simply plug in the module at diagnosis. Activation takes only seconds! After attaching the tool at diagnosis, you can choose the desired mode by using the steering wheel or the combination of additional buttons. It takes only 10 seconds to switch from mode to mode.

The module has 3 different modes:

  1. Factory – By choosing the mode, car level goes back to factory settings;
  2. Low – The Low option gives you the possibility to lower your car with -32mm in the front and rear parts.
  3. Custom – By selecting this feature you can select preferable height upon your wish for the front and rear parts separately (Min -70mm; Max +40mm;)

Note, you should close all doors and start the engine, once the adjustment is finished.

Advantages of the Mercedes lowering device

  • Lowering and increasing car level in one tool – You can use the tool not just for lowering, but also for increasing the height of your car;
  • Faster acceleration and quicker stops – There are stiffer springs in lowered suspension vehicle, that means less weight transfer, hence when you hit the gas or brake, you get a faster response;
  • Higher safety, less rollover risk – It’s well-known that lowered suspension decreases the center of gravity and we get less rollover risk while cornering;
  • Changing the look – Everyone agrees that lowered suspension cars are more attractive and attention-grabber;
  • Useful for a person with a disability – Lowered car makes it much comfortable to enter and exit; The tool is irreplaceable for a person with disabilities;
  • Better aerodynamicsIt’s a well-known fact that there’s less air movement underneath the lowered vehicle;
  • Space issue – If you have a roof rack on the car and garage with a low ceiling, you certainly need the tool.

Conclusion

All in all, I guess all the above-mentioned information was informative. Now you know how the air suspension system works, what is its main specification, what signs should be alerted and how to identify them. After reading all the information, I’m sure you know the answer about the main topic, whether you should drive with a bad pneumatic suspension or not. Of course, the answer is No. Also, we’ve got detailed information about the Mercedes lowering tool, which we can use on many occasions.
