Vehicle Dynamic Suspension: Compressor

The air compressor is located in the left-hand front wheel arch behind the bumper beam assembly. It contains an air filter, an integral regenerative air drier element plus an air exhaust solenoid valve. The compressor is isolated from the main body structure by 3 mounts, each incorporating a rubber bush and metal spring. The maximum pressure developed by the system is 15 bar (218 psi) with a compressor pressure relief valve fitted, set to relieve pressures above 17 Bar (247 psi). The compressor only operates while the engine is running. To guard against the compressor overheating the ASM may shut down the compressor to allow cooling to take place. Re-activation of the compressor depends on vehicle activity and is generally no longer than 120 seconds.
