How to Install Aerosus W211 Rear Air Springs

When your w211 rear air suspension starts to leak, it can cause the ride quality on your Mercedes-Benz to suffer.w211 rear air suspension It will become less comfortable and it may be harder to control your vehicle, especially when you are driving over potholes. Fortunately, you can fix this issue with a new set of rear air springs from Aerosus. These are an aftermarket replacement for your OE shock absorbers, which eliminate the need for the OE air reservoir and make installation much easier. This replacement can help you get back to enjoying the luxury and performance that your car is known for.

Getting the air springs on your w211 rear air suspension to work properly requires the following steps. First, you need to locate the air compressor. This is usually located in the trunk of the vehicle. It is a metal pressure vessel that is filled with compressed air at 13-16 bar. It is designed to control the height of your vehicle by sending a signal to the car’s air suspension system.

Next, you need to locate the valve that controls the struts and the pressure sensor. This is located on the left side of the vehicle, near the trunk floor. It is a black cap with a rubber valve that needs to be opened in order to change the air pressure. It also allows the air to flow in and out of the system.

You should also locate the air hose that connects the valve to the suspension compressor. This air hose is the one most prone to leaks. The reason is because the aluminum strut towers where the air hose is connected can corrode and pit from exposure to moisture. This will create a poor seal that can allow water to seep in and damage the compressor and other parts.

The rear struts are another part of the w211 rear air suspension that is prone to leaks. The air struts are monotube shock absorbers with electromagnetic damping valves that change setting based on commands from the suspension control module. They are also fitted with an air spring assembly that is responsible for adjusting the height of the struts. The air springs use two chambers, which can be filled with air for a firmer or softer spring rate.

One of the most common causes of a leaking air-suspension strut is when it becomes saturated with fresh asphalt. This can create a frozen layer of bitumen on the piston guide, which can accelerate wear and tear and shorten the life of the shock absorber. Another common problem is a puncture in the rubber air-spring bladder. This can happen if it is punctured while installing the strut or from a road debris.

Arnott has developed an aftermarket and remanufactured OE rear shock SK-3039 that fits the 2003-2009 E-Class (W211 chassis) and 2005-2011 CLS-Class (W219 chassis) including AMG models with AIRMATIC and ADS and without 4MATIC. This replacement will eliminate the OE rear load leveling and the need for the OE air reservoir, making it simpler and more affordable to install than the original Mercedes-Benz parts. These Arnott shocks are also backed by an exclusive 2-year limited warranty.
