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."

0703142018-11-26. Service bulletin. EQUIPMENT. Diagnosing Stored Fault Codes to Help Avoid Repeat Repair Visits. Analysis of FASTA data and repeat repair visit reports indicates that there are many fault codes that are stored in the above vehicles, but they are not diagnosed to identify their root cause. Fault codes that are not diagnosed to find their root cause can lead to a repeat repair visit to the workshop by the customer. Where diagnosis (vehicle or short test) with ISTA has already started, it is important to diagnose the fault code(s) listed below (when they are stored in the vehicle) during the current workshop visit. This will help lead to a reduction in workshop repeat repair visits and higher customer satisfaction.
6103142018-11-13. Service bulletin. ELECTRICAL SYSTEM. Check Control Messages Related to Battery Charge During Cold Ambient Temperatures. On cold days with an outside ambient temperature of less than 15F, customers may notice a check control message related to the battery that is displayed on the instrument cluster and the control information display. Under these conditions, the vehicle starts. Various power management faults can be stored: z 213901 - Power management: Reduction or shutdown of individual electrical consumer z 8040BD - Reset or deactivation of Terminal 30F z 8040B9 - De-activation of terminal 30B: Top start capability limit reached z 8020E8 - Reset or deactivation of terminal 30F z 800E89 - FRM: start capability limit reached with lights active during stationary mode z 93076B - Deactivation of terminal 30B: upper start capability limit reached z 93076A - Deactivation of terminal 15: upper start capability limit reached, but deactivation preventer active z 93076C - Deactivation of terminal 30B: upper start capability limit reached, but deactivation preventer or legal loads active z 930769 - Deactivation of terminal 15: upper start capability limit reached Note: When the outside temperatures drop below 46F, the charging system is switch to full charge. CAUSE z The check control message (ID 229) is caused by a heavily discharged battery. z The check control message is triggered when the current state of charge (SoC) of the battery approaches the minimum SoC that is required to start the vehicle (start capability limit). z In low outside ambient temperatures, the start capability limit of the vehicle is higher. Therefore it takes more energy from the battery to start a cold engine. z Without the early warning of the check control message, the current state of charge would drop below the start capability limit and the vehicle would not start. z The vehicle's intelligent power management system actively takes measures to increase the charge of the battery, such as increasing idle speed and reducing or shutting
