Ok ive been sorting through problems with my cars EAS. The fault message is "air susp inactive". Ive changed all four height sensors as two were broken. Ive reset all codes and suspension worked fine. Then it failed again the fault was "reservoir pressure static when filling". I read an interesting web site that said if i remove the pressure relief valve an replace it with the plastic valve thats attached to the compressor plug this could fix the problem. I did this cleared the fault suspension worked fine (really quickly tbh heard compressor working perfectly). Then the fault came back the pressure in the compressor was 11.1bar which this website said was fine. When driving above 60mph for a length of time the ABS HDC DTC warning lights come on but im putting this down to the fact the cars suspension should drop slightly on a motorway an it cant as suspension is locked in ride height an the fact that NO other faults for any of these systems are logged. Now ive been told of a pressure switch ???anyone know about these ??? TBH im NOT really convinced my problem is the compressor ! I know they are unreliable but how can it work perfectly AND really quickly AND have the correct pressure BUT still be faulty ? Im sure this is some other problem electrical, sensor, switch etc ? £350 is alot of money to throw away on a wim of it being the compressor ? Sorry to waffle on but its doing my head in now so any more advice would be gratefully welcome ! PS look at this http://quarterlogic.autologic-diagnostics.com/newsletter/2010/issue5/technical.htm
