Air Leaks in the AirMatic System
The AirMatic System is only going to continue to work properly if air is able to flow through all of the components. Once the air is no longer flowing as it should, the AirMatic System is going to begin to fail. This failure will become evident if you are all of a sudden feeling the bumps along the road. You may also notice that your Mercedes sits lower to the ground.
These problems may be caused by a leak in the AirMatic system. As each of the parts begin to age, they could experience cracks that result from general wear and tear or debris damage. If you suspect that an air leak is the issue then you are able to diagnose this at home. In order to do so, you can use soap and water, covering the part and watching for bubbles.
However, if you want a more definitive result then you will want to purchase a solution that is actually meant for flushing the system. Once you decide on the solution, you are going to spray it at the air suspension compressor fitting, air lines, the fitting of the valve block, and along the air hose. Next you will want to wait between 5 and 15 minutes to see if any of these parts has a leak. If the crack is small it may take a little longer for the solution to find its way out.
