Air Suspension
Air suspension replaces conventional coil springs with air springs fed by an onboard compressor, letting the car hold a set ride height whatever the load. This collection covers Bilstein air suspension modules and the compressors that feed them.

An air suspension module is the complete corner assembly — the air spring and damper supplied as one serviceable unit. It is the part that normally fails, because the flexible air spring perishes with age and road salt long before the rest of the system does. The compressor is the other common failure point: once a leaking module makes it work harder, the compressor wears out too.
Coverage is concentrated on the platforms that used air suspension most widely. Mercedes-Benz accounts for the largest share, followed by Jaguar, with BMW, Land Rover, Porsche and a smaller group of Volkswagen, Citroën, Peugeot, Renault, Fiat, Nissan and Opel applications also listed.
How to choose: the usual signs of a failed module are the car sitting low on one corner after standing overnight, a ride height warning, or the compressor running far longer than it used to. Replace the module that has failed, and check the compressor before assuming it survived — a compressor that has been running against a leak often needs replacing at the same time. Air suspension parts are strictly vehicle-specific, so use the vehicle selector to confirm fitment for your exact model and build.
