Reading Fault Codes on XK8

[jonywishbone]

I have a problem noted as a "suspension error" on my XK8 I have used the AutoEnginuity package but cannot retrieve any fault codes on this issue (does the engine fine) I was just hoping to isolate which shock absorber was causing the problem. Anyone got any experience or know of available packages to allow me to get further information from the ECU since if the warning lights on there must be something stored somewhere??
