Airmatic shocks are often located on the other side of the vehicle, usually at the rear. The airmatic system can be set to one of two pre-programmed settings “high riding” for normal driving conditions and “low riding” for use when encountering bumps or uneven surfaces.
When Airmatic is engaged, air is pumped into each shock chamber at a constant pressure until all chambers nearest to the bottom surface have expanded upwards to press against it. This provides extra clearance (up to 10mm) between bumpers, suspension beams and chassis components like exhausts and side skirts. When started up, this means that Airmatic automatically raises height by height depending on speed setting used; ie high ride height will only be utilised.
How To Reset AIRmatic Suspension? – [Explained]
AIRmatic air suspension systems are designed to provide a comfortable ride for drivers and passengers. However, if the system becomes overloaded or experiences an internal failure, it may need to be reset. This article will show you how to reset the AIRmatic suspension on your car. Keep in mind that this procedure should only be used as a last resort, as it may cause additional damage to the system.
AIRmatic Suspension in Mercedes
The AIRmatic Suspension in Mercedes-Benz cars was introduced in 1977.
The AIRmatic offers constant damping power to keep the car on an even keel, with no rebound of movements – even if they are large. This makes it easier for drivers to maintain contact with the road and make transient maneuvers like changing lanes or accelerating, while also offering passengers a smoother ride experience.
It is a self-adjusting hydraulic system which reacts to every ripple and hump in a roadway before they can produce a seat level jolt through your spine. It also helps cuts down on tire wear by regulating the shocks’ compression, so you have longer use from your tires before needing new ones if you own a Mercedes-Benz car.
Air Suspension Problems in Mercedes
Apparently the few things that could cause this are.
1) Air suspension advisory sensor failure
Air suspension advisory sensor failure can cause your car to lose air, which will make it difficult for the tires and wheels.
2) Compressor failure
Compressor failure is usually part of a system with a single-stage compressor and an auxillary electric unit to condense the refrigerant when the ambient temperature exceeds the freezer’s temperature setting.
3) Electronic control module malfunction in the vehicle
A vehicle’s control module can be the cause of many malfunctions, such as an electronic problem.
Sometimes if you disconnect your battery for a bit then reconnect it will reset it and fix whatever was wrong with it. I am not sure but, if there is a sensor or anything else hooked up to the air suspension pressure gauge within your vehicles instrument cluster then disconnecting the battery might also reset something internally as well.
But nonetheless without further digital diagnostics from a Mercedes Mechanic I am not sure what more to say about given these 3 possible solutions any one of them can be at fault here too.
How To Reset AIRmatic Suspension in w211, w220, w221?
Before reseting AIRmatic suspension, check that the problem isn’t with the height adjustment lever. Resetting AIRmatic can make height adjustment levers unusable. Open valve before starting work, only vent (do not open). Be very careful; high-pressure air can damage eyes or kill people if mishandled.
Bleed any pressure after service by cycling through all levels to release pressure and remove residual air. Clean fluid while bleeding for debris removal. Change filter while bleeding for performance improvement (replace every 15k miles).
When done turn knob to ON then RESET button then GATE button in that order; last step is locking pin back into place before opening valve again and pumping vigorously ten times into each wheel well/tower to clean.
How Do I Calibrate my Air Suspension?
If you need to calibrate your air suspension, you’ll need to use a special calibration tool.
First, you’ll have to turn the steering wheel all the way so one tire is at maximum lowered down to the ground while another tire is off of the ground completely.
Then have somebody hold the ratchet upwards while figuring out where on your car’s scale should be calibrated for that tire. Turn it back, then do this for each car wheel to calibrate it properly.
We hope this guide helps you through some of the most common problems associated with Airmatic suspension systems so you feel confident when dealing with any future issues.
