Air Suspension Problems and Solutions for the Mercedes W212

Air suspension mercedes w212 is a system that uses air bags in the rear of the vehicle and a control module to adjust ride height and damping characteristics.air suspension mercedes w212 It is an excellent option for anyone wanting to customize their Mercedes’ ride height and handling capabilities. However, it is important to understand that these systems are not fail-safe and that they require routine maintenance and repair. Here are some common issues and solutions:

Air Suspension Maintenance

The rear air springs on these vehicles are prone to leaks due to age, vibrations, and general wear and tear.air suspension mercedes w212 A small amount of air loss is normal, but if the air pressure gets too low or the compressor starts cycling on and off excessively it is time to replace the air springs. The rubber bladders can also deteriorate and start to crack. If this happens it is often best to replace the entire air suspension system (compressor, valve body, and rear struts).

Another area that has seen a lot of failure is the sensor that reads the height and sends that information to the control unit. This sensor can be prone to getting dirty, which can cause false readings and lead to the system not responding properly to commands from the control unit. A faulty sensor can also cause the rear level control module to turn on and off constantly, which can cause it to overheat and burn out.

If your car has the optional adaptive damping, it is worth mentioning that this system is also prone to failure. This is primarily because it uses the same shock absorber as the regular Mercedes suspension, and that shock can be prone to failure over time. The adaptive damping system works by adjusting the shock’s damping settings in response to acceleration, deceleration, and steering angle. This allows it to reduce axle-lift under hard acceleration and nosedive under heavy braking, which helps the vehicle maintain a more neutral handling feel and provides an overall better driving experience.

Air Suspension Repair

The air suspension mercedes w212 system is also prone to a lot of other problems including the compressor and the valve block, which can both burn out due to the constant cycling on and off of the system. It is also common for the rear air springs to deflate on their own which can be dangerous. If the rear springs are leaking but there is no warning light on the instrument cluster, you can test the level sensors by raising the car to its highest setting and measuring the height at each wheel location. Then, after allowing the vehicle to sit overnight and measure again, if one side is lower than the other it may be time to replace the level sensor or its linkage.

Each of our custom kits comes with a VIAIR 444C compressor which is rated to run at high pressures, and will help you get the most out of your suspension system. We also offer various management options to suit any budget, from our entry level bluetooth controlled 3S to the top selling 3P air management.
