122-K8T6V-102018-10-15. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. Subject: Instrument cluster Information: Due to a faulty Timer function for the internal clock in the instrument cluster, there is a possibility that the control unit system will be activated cyclically by the instrument cluster after stopping the vehicle. As a result, the control unit system will not be switched to energy-saving mode, resulting in increased closed-circuit current consumption. This can deplete the vehicle battery if the vehicle is idle for a long time.
