Suspension air bag deflated
The rear left suspension air bag is deflated.
Experienced mechanics share their insights in answering this question :
Hi. It’s not uncommon for the rubber in suspension airbags to get brittle and crack over time. Eventually, these cracks permeate through to the air supply and must be replaced. Usually, the compressor will re-inflate the airbag if its a relatively small leak. If you need further assistance, I recommend you have a mechanic, like one from YourMechanic, inspect for possible air leaks on your vehicle and replace the suspension air bag if the problem persists.

From time to time after installation it is not uncommon for the air suspension modules to be leaking and irreparably damaged. Usually, this is due to errors during the repair. If air suspensions do not appear to be completely tight after a repair or are apparently quite leaky, this can have very simple reasons.
No. It is not recommended. A damaged or collapsed spring can cause sagging and noise and affect alignment angles. While you can still drive, the ride will be rough and the car will be difficult to control in an emergency.
When air suspension fails, you`ll know it. The most likely first symptoms are a lower, sagging ride height, or the selectable ride settings that no longer function. Other symptoms include a rougher, noisier ride, and sloppy handling through corners and over bumps.
Press and hold both the “air down” and “air up” buttons on the dash for 5 seconds at the same time. Start your vehicle`s engine and enjoy your newly reset AIRmatic suspension.
Common signs include the rear feeling loose or spongy, a bouncy or rough ride, the air compressor running frequently, and sagging on one side.
Air Struts/Air Bags – 80,000-100,000 Miles
Air springs normally last 80,000 to 100,000 miles.
Damage to Shocks and Struts
In addition to obvious tire damage like a blowout, repeatedly running over potholes can cause damage to many other parts of your vehicle as well, including suspension system components like shocks and struts.
Lowering the suspension too low can lead to a variety of negative impacts on your Mercedes that include but aren`t limited to: Bottoming out- with your vehicle lower to the road, it`s easier for it to hit the road and also have trouble going over speed bumps or going through dips.
One of the most common Mercedes air suspension problems is a leaking air strut. As AIRMATIC systems start to age, the rubber around the strut can become brittle, cracked, or punctured. The seals and gaskets around the struts and the air lines can also wear out and cause a leak.
If you think you have a leak in your air suspension, you`ll want to get it looked at. Waiting to get an issue fixed with your air suspension can cause further damage to the system. However, getting your air suspension repaired can be expensive, especially if you take your car to get serviced at the dealer.
Failure of the air suspension tubing connecting the air struts or bags to the air system. Air fitting failure resulting from initial fitting or infrequent use. Compressor burn out due to air leaks in the springs or air struts from the compressor constantly engaging to maintain the proper air pressure.
Poor wheel alignment – this can cause damage to your tires and the suspension system, and make it hard to control your vehicle. A symptom of this includes your vehicle pulling to one side while driving. Bad shocks or struts – shocks and struts can break down and leak over time, which can decrease their efficiency.
If the vehicle sags at one corner or side, the easiest way to diagnose the air suspension problem is to put the vehicle on a lift and do a visual inspection of the air struts and springs, the ride height sensors, air lines and connections and the compressor (Figure 5).
The most common cause for failure in air bags is running them without the minimum air pressure. This causes them to bottom out, tear, etc. You should always keep 5 lbs. of air pressure in your air bags to prevent any damage.
The airbags and air struts in your air suspension kit are responsible for keeping your rides cushioned and adjusting the ride height. But like all air suspension parts, they break down and deteriorate as they get older, leading to air suspension failure. Rust can also damage the air struts.
It is not recommended. A damaged or collapsed spring can cause sagging and noise and affect alignment angles. While you can still drive, the ride will be rough and the car will be difficult to control in an emergency.
Yes. You can go fast on air suspension, but it will have limitations regarding extreme motorsport events. Many enthusiasts and professional racers use air suspension on their race cars with great success.
Most new Mercedes-Benz vehicles usually come standard with steel-spring suspension. It is the most common type of suspension in passenger and commercial vehicles because it is inexpensive, simple, and has been known to outlive the cars it is put in.
More often than not, it`s caused by the AIRMATIC`s compressor failure. The AIRMATIC`s compressor regulates the system pressure, raising or lowering the car as required. Malfunctions of the compressor, such as motor burnout, are what cause the vehicle to sit low.
While most AIRMATIC systems can go 120,000 miles without any service or repair, sooner or later a failure will occur.
Ride Comfort
If you`re experiencing a bouncy vehicle, it`s most likely the result of a weak suspension. If your vehicle is bouncing up and down slowly because the load is too heavy for what the suspension can handle. If this is the case, you want to increase the air pressure in your air springs.
The short answer is no – you should not drive a car with broken suspension. Regardless of whether it`s a broken coil spring or a broken shock absorber, you cannot drive a vehicle which has any element of the suspension that is broken.
The airbag of a car cannot be fixed after an accident. Even though it can be costly, you must have it replaced. Manufacturers design modern airbags for a single use. When they were first introduced, mechanics could reset some airbags.

What do the air bag On and air bag Off lights mean on the dash?
ANSWER : Depending on whether the front passenger occupant classification system detects that the passenger front seat is empty, detects a child, or determines the passenger is an adult, it will turn on or off different lights, as well as controlling the air bags. Here’s what you should know:
Adult
If the system detects that an adult is present in the seat, the air bag On light will light up. The supplemental restraint system (SRS) warning light will be off. The front air bag, the side air bag and the curtain shield air bag will all be active. The Seat Belt light will flash if the seat belt isn’t buckled.
Child
If the system detects the presence of a child in the seat, the air bag Off light will be turned on. The SRS light will be off. The front and side air bags will be turned off, but the side curtain air bag will stay on.
Empty
If the seat is empty, the air bag Off light will be on, the SRS light will be off, and the front and side air bags will be turned off. The side curtain air bag will still be active, though.
Tip
If the air bag Off light is on and the SRS light is on, it means there’s a malfunction in the system. Have the car inspected.

Air compressors and air suspension fail
ANSWER : This is a common fault that is found with vehicles that have air suspension. Though the compressors were most likely bad the first time, there is another problem causing them to fail. The most common would be a leak in the system or a failed air strut.
When the strut fails or a leak is present, it can cause the air compressors to never shut off as they try to compensate for the leak which causes them to fail prematurely. A qualified technician, such as one from YourMechanic, will be able to inspect your suspension system and make a proper diagnosis on the issue.

the left front air suspension dropped, No codes, compressor works. Bag fills but not enogu to lift
ANSWER : You have great diagnostic skills! In addition to the components you have listed, it’s also possible the air line to that corner has a leak, or the solenoid itself has a leak. Unfortunately, this is a chronic problem with model – causing many to abandon the air suspension, and revert to traditional spring/strut packages. If you’d like, YourMechanic can dispatch a certified professional mechanic to your location to perform a Suspension system inspection and repairs.

’08 Nav Needing Air Suspension Help
ANSWER : It is possible that you could have a restriction in the line that goes from the compressor to the rear air spring. This resriction would prevent the air from reaching the air spring. I would recommend dis connecting the line at the compressor and at the air bag and shooting compressed air through the line to make sure it is not restricted. If something comes out of the line, you should be able to reconnect the lines and the air suspension system should work properly again.

Hot air mixed with cold blows from air conditioning
ANSWER : Hey there. You will most likely have to have a mechanic bypass the heater coolant lines to have this resolved. Your A/C may not be controlling the air flow inside the evaporator correctly out of the vents and may be the blend door actuator stuck in the heat position. Have the AC system diagnosed first before bypassing the heater.

Cold mist/smoke like air comes out of the air vents when cold air is on.
ANSWER : If you are using regular outside air a/c instead of recirculated air you may be getting a large amount of outside air humidity and can cause a mist to come out of the a/c vents. You should make sure the a/c evaporator drain is cleared and drains freely or the water in the a/c cannot drain fast enough and the blower will pick up the water and blow it out the vents.

I am wanting to know if Air shocks or air lft suspension kits are better for pulling a trailer or heavier load ?
ANSWER : Any type of lift (whether air, air adjustable load leveling shock, automatic or manual, or helper springs) is going to give you basically the same effect. Leveling the load, due to the tongue weight, will not keep the transmission and clutch from wearing out prematurely if you go over the 2,500 pound limit. I presume you are contemplating using trailer brakes but at 4,000 pounds that raises control issues if the tow vehicle is rated for 2,500 pounds. Another issue you might consider is whether the rear sub-frame of that model can accommodate the tongue weight likely to be encountered with a 4,000 pound trailer. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you. And, please continue to keep us in mind for maintenance and repairs.
