8402142018-11-13. Service bulletin. ELECTRICAL SYSTEM:SOFTWARE. ConnectedDrive/BMW Assist System Diagnosis Information. ConnectedDrive/BMW Assist features are partially or completely inoperative. This Service Information bulletin is being published because vehicles are down for an extended period of time when researching system failures with ConnectedDrive or BMW Assist. This Service Information bulletin will assist you both in identifying the issue and providing technical support. CAUSE Not enough information is available for BMW NA engineers to assist the technician in diagnosing the root cause.
6606142018-11-13. Service bulletin. BACK OVER PREVENTION. Rear View Camera Does Not Display Image on CID. After engaging the reverse gear, the reversing camera does not display a picture in the CID (Central Information Display). CAUSE The drive mechanism for the roundel actuation in the boot lid is faulty.
6604142018-11-13. Service bulletin. FORWARD COLLISION AVOIDANCE. Front Collision Warning Check Control Message Displayed in CID. Occasionally while driving, a check control message (CCM) for Front Collision Warning is displayed in the Central Information Display (CID). This message is cleared from the CID by clicking on "OK" using the iDrive controller. CAUSE The KAFAS (camera-based driver support system) camera is affected by environmental conditions such as: * Direct sunlight (sunrise or sunset) * Rain * Fog * Dirt * Snow * Ice * High interior temperatures (may also cause a CCM to be displayed upon starting the vehicle) ?? Fault code 0x800AC0 - KAFAS camera switch off due to over temperature The pictures below show the direct sunlight causing the CCM: INFORMATION This is the current text in the Owner's Manual for the Front Collision Warning (FCW): The system may not be fully functional in the following situations: * In heavy fog, rain, sprayed with water or snowfall * In tight curves * If the driving stability control systems are limited or deactivated: for example, the DSC is off. * If the camera view field of the front windshield is dirty or covered. * Up to 10 seconds after the start of the engine, via the Start/Stop knob. Direct sunlight will be added as one of the causes for the FCW CCM.
6521132018-11-13. Service bulletin. ELECTRICAL SYSTEM; SEATS. When Unlocking with Comfort Access the Outside Door Mirrors Are in the Wrong Position. The vehicle is locked with one remote key and then enters sleep mode. The vehicle is then unlocked using one of the outside door handles with the second remote key. The outside door mirrors do not move to the correct position. The seats do move into the correct position. CAUSE Software error in driver's seat module
6502142018-11-13. Service bulletin. EQUIPMENT. Headunit High Is Constantly Resetting. After connecting a mobile device via Bluetooth, the Headunit High (HU-H) constantly resets. This is because the mobile device paired/connected to the vehicle contains one or more emails with 30 or more recipients. Note: In this situation, a reset is when the HU-H shuts down and then turns back on. CAUSE Software error in the HU-H.
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 15°F, 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: * 213901 - Power management: Reduction or shutdown of individual electrical consumer * 8040BD - Reset or deactivation of Terminal 30F * 8040B9 - De-activation of terminal 30B: Top start capability limit reached * 8020E8 - Reset or deactivation of terminal 30F * 800E89 - FRM: start capability limit reached with lights active during stationary mode * 93076B - Deactivation of terminal 30B: upper start capability limit reached * 93076A - Deactivation of terminal 15: upper start capability limit reached, but deactivation preventer active * 93076C - Deactivation of terminal 30B: upper start capability limit reached, but deactivation preventer or legal loads active * 930769 - Deactivation of terminal 15: upper start capability limit reached Note: When the outside temperatures drop below 46°F, the charging system is switch to full charge. CAUSE * The check control message (ID 229) is caused by a heavily discharged battery. * 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). * 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. * 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. * 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 shut
8403142018-11-13. Service bulletin. ELECTRICAL SYSTEM. iPhone: Connection Failures with iOS 7. There are various connectivity failures with the iPhone using iOS 7.

When there is a low tire pressure warning, in some cases the position of the affected tire may be incorrectly displayed in the instrument cluster and CD (Control Display). Software error in the RDC (tire pressure control) module in conjunction with wheel electronics part number 4 078 787 or 4 079 152.
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.
