The owner had taken the vehicle to a Mercedes-Benz mechanic who recommended the air suspension compressor. You don’t need to replace the air suspension compressor to fix this problem.

Possible Solutions

1. Jack up the vehicle and secure it. Remove the wheel by the air compressor suspension. The air suspension compressor is located behind the front bumper. You access it by removing the lower splash shield or the wheel well liner. Depending on the model, it is on the driver’s or passenger’s side.
2. Locate the air suspension release valve.

Here is what you need to do.

1. Check the wire harness to the air release valve (solenoid). The wire harness that connects to the air suspension compressor can get damaged. Once this happens, you will get the Airmatic Failure Visit Workshop on the dashboard.
2. Remove the air release valve and ensure it is not stuck. Cleaning the air release valve can sometimes fix the problem. Especially if the plunger is stuck due to dirt or rust built around the solenoid.
3. Replace the air release valve. Sometimes you may not be able to fix the air release valve. If you find another unit, you can only change the air release valve. It is held in place with two 25 Torx bolts and takes less than 5 minutes to replace.
