THE FAULT The piston seals within your vehicles EAS air compressor are likely worn, filters saturated and the dryer end cap failing reducing output significantly. The likely cause of the faults noted above and most common cause is a worn piston and glide ring within the air suspensions compressor unit. Coupled with saturation of the filters in the compressors drier unit. This results in reduction of compressor output and triggers vehicle faults as well as extending the time taken to lift the vehicle. The original design for the dryer end cap was poor and cracks can develop around the air line collets causing leaks and vehicle faults. However, whilst refurbishing the compressor, the components within the non-return valve (also known as the delivery valve) get lost or break. The plunger within the valve commonly deteriorates and leak, causing the compressor to leak internally. Also, the screw itself often becomes damaged upon removal.
