Remove the black plastic panel under the engine. There may be as many as 3 panels under the car. You need to remove the first panel right after the front bumper. Once you remove the panel, you will see the air compressor right behind the front bumper, underneath the headlight on the passenger side. For demonstration purposes, we are showing pictures with the bumper removed. You do not need to remove the front bumper.



Remove the plastic airline that goes into the air compressor. Using a 10 mm wrench, turn the bolt counterclockwise. Once the bolt is loose, pull out the airline. There is a small rubber gasket on the metal connector at the end of the threads; make sure not to damage it. MERCEDES-BENZ_air_matic_air_compresor_repair_how_to_replace_09

Remove three nuts that hold the air compressor in place using a 10 mm wrench. You may want to spray some anti-seize such as WD-40 on the nuts before you remove them. The bolts can easily break if they are rusted.


Remove the hose that connects to the intake air filter. Using your pliers, slide the clamp over, then pull on the rubber hose. MERCEDES-BENZ_air_matic_air_compresor_repair_how_to_replace_26
