How to Replace Your Citroen C4 Picasso Air Suspension Compressor

It’s hard to go wrong when you ride in the Citroen C4 Picasso and Grand Picasso. After all, with such a unique and trendy design, there’s no mistaking this head-turner for anything else on the road—even by today’s standards. Plus, you’ve got the air suspension delivering such a stellar and smooth drive that even potholes and raised curbs seem virtually unnoticeable when you cruise over them. Not to mention, this system also allows you to take tight turns and corners at a quick pace while still remaining in control for a sporty touch to your cruises.

What You’ll Need for the Repair:

• Basic Toolbox with essentials inside (i.e. Socket wrench, flat screwdriver, etc.)
• Car Jack
• Anti-Seize Spray to loosen up any stiff parts

How to Replace Your Citroen C4’s Air Compressor in Less Than 45 Minutes

2. Use a Socket wrench to unscrew the nuts on the protective shield over your air suspension compressor. You’ll find three different nuts to unscrew before you can remove this piece.

3. Unfasten your air line. This piece is a white-colored tube—you can remove it with your hands.

4. Unplug the two electrical components. The wires of these pieces are protected by black tubing—you don’t need to remove the tubing; just take out the plug-in part. If these plugs feel stuck, consider using a flat screwdriver to help you pry the pieces apart.

5. Unscrew the nuts on the holding plate above your air suspension compressor. You’ll start by unscrewing the three nuts with a socket wrench. You’ll also see where the black tubing protecting the wiring from step 4 is hooked onto the connected plate—unhook this piece; you can now remove your air suspension compressor from your car with the above plate still attached.

6. Remove the bolts from the top side of the connecting plate. A socket wrench is all you’ll need to remove the three bolts. Once removed, you can disconnect this plate from your old air suspension compressor.

7. Install your new AEROSUS air compressor. From here, you’ll essentially complete the above steps in reverse order. This includes reconnecting the top plate by inserting the three bolts. Reinsert your plate to your Citroen C4 and insert the appropriate three nuts. Reconnect the electrical prongs from step 4. Then, reconnect your air hose and re-insert the protective shield that goes over your air compressor.

8. Lower your car to the floor.

9. Install your relay switch.

10. Start your car. Let your Citroen Picasso run a few minutes to give your vehicle a chance to adjust to the fixes you just made.
