The Simple DIY Guide On How To Replace Air Suspension Compressor Mercedes S500

First, read this disclaimer;

Although the designs for air suspension compressors vary from one Benz to another. Nonetheless, it’s the exact procedure for replacing the air suspension compressor in the Mercedes S class that would guide you when it’s a GL class, E class, or CL-class.

With that in mind, let’s check out this simplified approach.

The Step-By-Step Procedure For Replacing Air Suspension Compressor

Step 1; Power on the ignition, straighten the wheel of the car and then switch it off.

Step 2; raise the car at the front end. Do this with aid of a car ramp or hydraulic jacks. When using hydraulic jacks, ensure you place chocks at the rear tires so the car doesn’t shift position when you’re working on it.

Step 3; Pull away the black plastic panel away from the front end of the car. Usually, you will find three layers of the panel and yeah, you guessed right you have to pull away all three to access the air compressor but not in this case.

Step 4; In this case, you have to remove the first layer of the black panel right after the fender and you’ll find the air compressor of your Mercedes Benz S500 sitting underneath the headlight of the passenger seat.

Step 5; With the aid of an appropriately sized wrench (12mm precisely), disconnect the airline from the air compressor. You also have to ensure that you do not cause damage to the rubber gasket on the metal connector at the end of these air threads.

Step 7; Unplug the pair of electrical connectors linked to the Mercedes S500 air compressor. One of these pair controls the air compressor while the other controls the air outlet valves. Disconnect the electrical connectors carefully by pressing the release tab on the connector.

Step 8; To remove the air compressor, you first have to loosen the three nuts holding the air compressor in position. If these nuts prove stubborn you can first spray with a rust breaker or use an electric nut remover instead of a wrench.

Step 9; With the aid of nose clip pliers, disconnect the air intake valve from the compressor.

Step 10; Now you can remove the air compressor and prepare for the installation of its replacement.

Step 11; In reverse order, reconnect all connections and tighten all nuts you’ve earlier disconnected.
