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.

0104142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING. External Engine Oil Leaks and Repairs. During the vehicle's operational life, normal engine oil seepage or sweating, in addition to accumulated road dust, dirt and grime in the engine compartment can cause the appearance of a more severe oil leak. This is further exaggerated by residual oil that remains on the engine assembly after maintenance services are performed, e.g., oil filter changes, "engine oil top-offs," etc. If this visual appearance of accumulated oil on the engine assembly as an "active leak" is misinterpreted, unnecessary gasket repairs/replacements will result. Specifically, our analysis of the claim-related data for vehicles equipped with the engines noted in this bulletin is showing an above-average number of engine gasket repair/replacement claim submissions. The purpose of this bulletin is to provide your workshop with information and a procedure that will help in identifying engine oils leaks that do and do not require a repair.
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."""

This Service Information bulletin supersedes SI B65 05 09 dated July 2009. designates changes to this revision SUBJECT CIC Headunit: Navigation System Road Map Usage. INFORMATION The Car Information Computer (CIC) began replacing the Car Communication Computer (CCC) on vehicles with option 609 in September of 2008. This change affected the navigation system road map data support process and the warranty spare parts processes for the CIC. For the US market, all vehicles come pre-loaded from the factory with the latest navigation system road map database version that was available at the time of vehicle production. Therefore, no physical copy of the navigation system road map data media DVD set or USB stick is placed in these vehicles at the Vehicle Distribution Center (VDC). NOTE: Additionally, all replacement CIC parts come with a pre-loaded version of the current available navigation system road map database installed. A set of DVD copies of the navigation system road map database, CIC NAVI Road Map North America PREMIUM, is shipped to all BMW centers through the automatic tool shipment program with each release of a navigation system road map database. IMPORTANT: Additional copies or earlier NAV road map database versions cannot be ordered individually! Therefore, please take special care to archive the CIC NAV road map DVD sets! The NAV road map data on the DVD set can also be installed into the Network Attached Storage (NAS). From there, it can then be installed onto the CIC in the vehicle, using the Integrated Service Technical Application for Programming (ISTA/P). For installation of the navigation system road map data media DVD set onto the Network Attached Storage (NAS), please contact your ISPI Next Administrator. In addition to this procedure, it is also possible to download the NAV road map data on the DVD set directly to the hard disc drive (HDD) integrated in the CIC by inserting the DVDs one by one into the CIC internal DVD drive. It will take approxim
