    2008 328i has developed an Active Steering Fault. The indy says it needs an active steering control module by process of elimination of other faults. Are bench tests of this module not available?
    Thanks in advance for any thoughts.
    Error codes are :
    CAS [CAS] | A0B4: Engine start, starter operation
    DSC [DSC_87] | 5E52: Active steering: interface
    KOMBI [KOMB87] | A559: Dashboard: Voltage supply has been switched off (standby current cutoff relay)
    AFS [AFS_70] | 6140: Redundancy comparison, driver's steering angle
    AFS [AFS_70] | 614A: Motor position angle: not initialized
    AFS [AFS_70] | 6146: Control unit cannot change to active mode, undervoltage
    AFS [AFS_70] | 6144: Monitoring, self-locking
