How to Replace your Faulty Mercedes S Class W221 Compressor?

If you own a Mercedes S Class W221, you know how important having a properly functioning air suspension system is. Unfortunately, like any other vehicle, your air suspension may eventually need to be replaced, and the compressor can be the first component to go. Replacing the compressor in your W221 can be a difficult task, so here’s a guide to help you get the job done.

First, you will need to locate the compressor. The compressor for the W221 is located under the hood and is typically found on the passenger side of the vehicle. You may need to remove some components to access the compressor, such as the air filter housing, air intake hose, or the air box.

Once you have located the compressor, you will need to disconnect the air lines from the compressor. There should be two lines, one for the intake and one for the output. Carefully disconnect the lines and be sure to keep track of which line is which.

Next, you will need to remove the bolts that secure the compressor to the engine. Depending on the type of compressor your vehicle has, there may be several bolts that need to be removed. After all of the bolts have been removed, the compressor should be free to pull out.

Once the old compressor is out, you can install the new one. Be sure to install it in the same place as the old one and make sure that all of the bolts are tight. After the new compressor is in place and the bolts are tightened, you can re-attach the air lines. Double-check that all of the connections are secure before you start the engine.

Finally, you will need to add air pressure to the air suspension system. You can do this by using a hand pump or a pressure gauge.

Make sure that the pressure is within the manufacturer’s recommended range.

Replacing the compressor in your Mercedes S Class W221 can be a difficult task, but with the right tools and a bit of patience, it can be done. If you have any questions about the process, contact a professional for assistance.
