Air Suspension Compressor Pump to fit Jaguar XJ8 2004-2009. Most Air Suspension Compressor failures are caused by a compressor being overworked or running more than it's supposed to. Leaking Air Struts and Springs are often the cause of a compressor overworking, but there can be leaks elsewhere in the system and all leaks must be located and fixed before replacing the Air Compressor.
