In the instrument cluster, the symbol for "12 V battery" and the message "Switch on vehicle" may sporadically be displayed. As a consequence of this, the fault codes B 1 FCB97 (=> N73/3) and U 116000 (=> N73/3*1) are stored in the fault memory. In the subsequent analysis of the 12 Von-board electrical system data, the following parameters are conspicuous (see picture 1 in the attachment): Charge balance negative when stationary. Interior CAN bus is awake for an unusually long time. 12 V battery SOC (state of charge) during subsequent engine start is 45% or less. NOTE: Once the 12 V battery SOC has exceeded 50% for the first time, the symbol and the message in the instrument cluster disappear again. The door control unit (N69/x) may sporadically keep the interior CAN bus awake. NOTE: Exclusively door control units with the HW item numbers A2239019917 and A2239010018 can be affected. Open a TIPS case and include the following: 1. Initial Quick Test 2. N73/3 EZS CUL 3. N73/3*1 EZS CUL 4. Date and time of occurrence

Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
