Mercedes Air Suspension Valve Block Replacement

Mercedes Air Suspension Valve Block Replacement

When your Mercedes has an air suspension system it allows you to raise or lower the vehicle at the push of a button, giving the car more ground clearance or a smoother ride quality depending on driving conditions.mercedes air suspension valve block However, just like other components on your Mercedes, the valve block that controls the air flow can fail and cause a number of problems.

The Airmatic valve block is responsible for distributing air pressure from the air suspension compressor to the air struts and air springs based on commands sent by the suspension control module.mercedes air suspension valve block The valve block also connects to the air reservoir and level sensors that collect information on the height of each axle. If any of these components are faulty it can result in a loss of ride height, suspension problems or a warning light on the dashboard.

One of the most common issues with this part is a leaking air line connecting to it. This is caused by o-rings drying out over time, and moisture can damage the electrical solenoids inside of the valve block. The best way to check for this issue is to remove the short air hose from the valve block and place it under running water. If there are bubbles forming, it is likely that the air is leaking back through the valve block instead of to the air strut.

Another potential problem is a loss of ride height due to the valve block not receiving enough commands from the suspension control module. If this is the case, it can be a simple solution to replace the air suspension control module. Another option is to replace the valve block itself, as this can typically be done without replacing the air suspension compressor or removing the air tank.

The main air reservoir is a metal pressure vessel that stores compressed air at 13-16 bar. This is a safety feature to reduce the amount of work needed by the air suspension compressor and prevent overworking it and overheating. The main air reservoir also stores excess air to provide a buffer in the event of an emergency when the vehicle needs to be raised quickly or the compressor isn't working properly.

If you're looking to replace your Mercedes E-Class W212 2010-2016 air suspension control valve block, look no further than RMT's M212-A225-AD4U. Each of these new OE design valve blocks is tested electrically and pneumatically to ensure that they meet or exceed the quality and performance of your original Mercedes-Benz parts.

The valve block unit (Y36/6) is located near the air suspension compressor and contains a series of solenoids that open and close to direct the airflow to each air strut or to the air reservoir. It can also be controlled by the onboard suspension computer via a set of sensor signals and is connected to both the air suspension compressor and the pressure reservoir.

The fuse and relay for the air suspension system are located in the engine compartment's right front passenger footwell behind the passenger headlight. Check the 40 AMP fuse F32 to make sure it is not blown. It may be difficult to access this fuse box as the passenger side carpet and floor panels must be removed.
