how to spot a faulty air suspension compressor

Many SUVs and luxury cars come with air suspension systems. The purpose of the air suspension is the same as standard, coil-cover springs or gas-filled shocks and struts. They raise the chassis off the axle and cushion the vehicle against bumps and jarring movements.

Air suspension uses a system of inflatable air bags which swell up with compressed air to raise the vehicle off the ground. And just like a standard suspension can develop faults or sustain damage that require repairs or replacement, an air suspension system can also get damaged.

The air compression system is a more advanced suspension system. As such, it comes with certain complexities, such as a more diverse range of components, which are missing in standard suspension systems.

One such critical component is the air compressor. Any damage to the air compressor can lead your car to develop certain problems like the compressor not starting or making abnormal sounds. And without the required suspension support, you may find your car is riding low.

Air Compressor Issues

If the air compressor develops a fault, the chassis might not lift, or only partially lift, off the axle. This could then lead to the above-mentioned problems. The important thing is to identify the symptoms of a faulty air compressor so that a replacement can be initiated as soon as possible.

Here are three questions you should ask to help diagnose a faulty air suspension compressor:

Is Your Car Suspension Sagging?

If there is a problem with the air suspension compressor, one of the first aspects you will notice is that your car’s suspension is sagging.

Is the Air Compressor Generating Abnormal Noises While Operating?

The generation of abnormal noises, while the air compressor is operating, is another indication of a faulty air compressor. Here’s what you need to know:

Is Your Car Air Compressor Not Functioning at All?

The air compressor turns on and off based on the requirements of the suspension system. The suspension itself is designed to self-regulate the compressor.

Key Concepts

As mentioned above, air suspension systems are not simple. It is not uncommon for these systems to give way without any kind of warning signs. However, if you notice any of the symptoms mentioned above, it is best to have your car checked up by a professional mechanic right away.
