Citroen C4 Picasso/Grand Picasso Air Suspension Compressor

It isn't easy to produce spare parts for air suspension at the same level as Citroen, as the French manufacturer has been using air suspension systems since the 1950s. Nevertheless, we have done it and we offer our compressor for the highly successful Picasso. Our brand new Aerosus compressor is designed for all models of Citroen C4 Picasso and Grand Picasso from 2006 to 2013. It is delivered assembled and ready for installation. A solid-state relay (semiconductor relay) is already installed in the controller of our spare part. An exchange of the relay can therefore be omitted. In addition, the valve block for the controller is integrated into the compressor. The compressor can be found in the lower rear part of the vehicle, within a black box found almost in the middle.

Reputation as a Safe Mid-Range Vehicle
Since the start of production, the Picasso has earned a good reputation as a middle-range vehicle. The built-in air suspension for the rear axle has contributed greatly to this, as it offers advanced and quite unexpected road handling. At the heart of the air suspension system is the compressor, which supplies the air springs of the level control system with sufficient dry compressed air, thus contributing to greater safety and comfort.

Components of the Aerosus Compressor
Our self-levelling compressor consists of four main parts: the air is compressed in the compressed air housing. The necessary drive is provided by the strong electric motor. The air dryer provides the system with dried compressed air. Finally, the integrated solenoid valve block distributes the compressed air to the air springs on the right and left of the rear axle. Compact and modular, our compressors provide safety and stability with minimal noise. In addition, our spare part impresses with its simple installation.

Why is the Level Control defective?
If the level control has failed, this is almost always due to leakage of the air suspension. When an air spring is leaking, the vehicle lowers on the rear axle overnight. The compressor runs for too long, lets humid air go through, and the vehicle tilts. If the compressor makes loud banging noises, you should quickly think about an exchange. A defective level control doesn't pump up, and then, as a result, the compressor fails to generate enough compressed air and overheats. The vehicle lowers on one side at the back and remains in this position.

Simple and Comfortable Installation
The Solid-state relay, a solid-state relay required for the operation, performs its service immediately after the installation of the compressor. When performing the replacement, note that the air ducts are produced in the same colours as the compressor inputs. Our engineering teams, who along with the development are also responsible for ongoing quality tests, have done a great job in making the exchange as easy as possible. At the end of the day, expert control in Germany pays off.

Our Compressor's Warranty
If the new car part has found its place in the vehicle, it's necessary to carry out an overall test of the air suspension. Our Aerosus compressor in original equipment manufacturer quality is equal to the original part. Enjoy long-term stability, quality and thus safety whilst driving. You will get low prices for our compressor if you buy it online. If you are not satisfied, we offer a 30-day money-back guarantee in addition to our 2-year limited warranty. With our Aerosus compressor, you can enjoy a maintenance-free spare part that secures the functionality of your air suspension for a long time and therefore contributes greatly to safety and driving pleasure.
