6113052018-12-03. Service bulletin. ELECTRICAL SYSTEM. "Discharged Battery: Energy Diagnosis Must Be Performed. The electrical system of BMW vehicles has been subject to an ongoing development process over the last few years. This has led to increased demands being placed on the battery. This document covers important information for the dealer on how to handle ""discharged battery"" complaints. A discharged battery can have various causes, most of which do not concern the battery itself. A failed battery is often the symptom and not the cause. A fully serviceable battery fails when an electrical component causes the battery to discharge; the battery becomes internally damaged and must be replaced. For more information, refer to www.batteryuniversity.com/parttwo-42B.htm For this reason, replacing the battery is not usually a permanent repair. The cause of the discharged battery must be analyzed in order to guarantee a proper repair. In order to properly repair the vehicle the first time in the workshop, it is very important that the diagnostic test plans are performed to completion with all results taken into to consideration. The procedure as outlined below contains information that will guide the technician into properly repairing the vehicle and getting paid for a warranty claim. CAUSE Refer to the ""Procedure"" section of this Service Information for details."

6522142018-11-13. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM(GLOBAL POSITIONING SYSTEM). Automated Activation of Navigation System During PDI/QC1. INFORMATION Important: The INITIAL NAV enabling code no longer needs to be pre-ordered through the Parts department! When the vehicle is connected to the diagnostic system ISTA to perform PDI/QC1, the step to activate the navigation system (part of Delete Transport Mode) will automatically request the INITIAL NAV enabling code (VIN-specific) without pre-ordering the enabling code. This enabling code will be automatically delivered through ISTA and it then activates the navigation system. Note: This VIN-specific NAV enabling code is then also automatically stored in the Repair Kit in the Aftersales Assistance Portal (ASAP). The automated INITIAL NAV enabling code request and activation of the navigation system will take no longer than 1 minute. After finishing "Delete Transport Mode," the navigation system in the vehicle will be active without entering the 20-digit INITIAL NAV enabling code manually or in ISTA. If the navigation system is not active and asking for the enabling code, turn off the ignition and wait for the head unit to enter sleep mode (approx. 3 minutes). After that, turn on the ignition again. The head unit will start up and the navigation system is activated. If the INITIAL NAV enabling code for first-time activation of the navigation system is not requested or delivered automatically, it still can be ordered manually through the Parts department and activated in the vehicle through the iDrive controller, by entering the 20-digit enabling code manually.

6117142018-11-13. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. "Intelligent Battery Sensor Diagnosis Hints. The vehicle enters the workshop with one or more of the following complaints: * Check Control Message related to battery discharge * No-start condition * Consumer power reduction (reduced blower speed, heated seats operation, etc.) * The following fault codes may be stored in the DME a. 2E8B - Intelligent battery sensor, signal b. 2E8C - Intelligent battery sensor, function c. 2E8D - Intelligent battery sensor, signal transmission d. 2E8E - Intelligent battery sensor, communication CAUSE A faulty battery or IBS sensor (not both) The power management system and IBS in the vehicle cannot determine if the battery needs to be replaced. This is normal operation for all E-Series vehicles because they do not have the Advanced IBS sensor that the F-Series vehicles do. An external battery tester (Midtronics EXP-1000) must be used to determine if the battery needs to be replaced. Energy Diagnosis will not prompt for a battery replacement unless the battery is ""aged."" When energy diagnosis identifies the battery as ""aged,"" it means the amount of energy discharge over the course of the life of the battery has reached its maximum (worn out). In most cases, energy diagnosis states that the battery is OK. This is typically an indication of the current State of Charge (SoC), not the State of Health (SoH). The SoC is defined as the current amount of energy left in the battery (displayed as a percentage). The SoH is defined as an evaluation of the condition of the battery over a period of time (displayed as a percentage). For more information about batteries, refer to Training Manual ST051, ""07 Battery Basics."""
