I have an XJ x328 2.7D which I love however I am having trouble with my air suspension in that an air suspension fault comes on when a road gets bumpy, My Jag garage changed the air compressor but the fault has come back after a few weeks and occassionally results in vehicle too low warning which resolves itself. Should I change my dampers front and back or should I do something else prior to doing so. Is it possible for the problem to be caused by air escaping from the system on bumps and it being more a problem of ensuring all the air piping and joints being very tight? The air fault goes off every time the engine is restarted.
I am not convinced changing all the dampers (not cheap) will eliminate the problem.
