Service bulletins for the 2012 BMW 528i

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

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.

FC 193208 Fuel level, plausibility: deviation between consumption and level change Vehicles with option 610 (Head-Up Display) are not affected. Follow the ISTA/D test plan for the applicable faults stored in the DME. CAUSE A software error in the instrument cluster causes the fuel gauge to incorrectly update while refilling.
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.

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

1224132018-11-13. Service bulletin. ELECTRICAL SYSTEM; ENGINE. "PERFORM THE PROCEDURE OUTLINED IN THIS SERVICE INFORMATION ON ALL AFFECTED VEHICLES BEFORE CUSTOMER DELIVERY OR THE NEXT TIME THEY ARE IN THE SHOP FOR MAINTENANCE OR REPAIRS. BMW centers must ensure Recalls are completed after having been notified by BMW of North America, LLC (BMWNA) that a safety-related defect or noncompliance exists in any motor vehicle or item of replacement equipment in the center's possession at the time of notification. In BMW NA's case, this notification would typically be made by the issuance of a Recall notification in the form of a Service Information bulletin (SIB) or transmission of a Dealer Communication System (DCS) Recall message. Under the National Traffic and Motor Vehicle Safety Act of 1966, as amended, if a Recall Campaign is announced by BMW NA, centers must ensure that all Recalls on new vehicles and new items of replacement equipment are completed BEFORE delivery to the consumer. This means that centers may not legally deliver new motor vehicles or new items of replacement equipment to consumers with an open Recall. The Safety Act also prohibits centers from selling or leasing the motor vehicle or item of replacement equipment, unless and until the open Recall has been completed BEFORE delivery. This also pertains to vehicles in the Certified Pre-Owned program, and to items of replacement equipment. Finally, BMW centers should not sell or use parts that have been recalled by BMW NA. Please follow the specific instructions provided by BMW NA on the return or disposition of the parts. designates changes to this revision SUBJECT Voluntary Emissions Recall Campaign 13E-A03: Program Control Units (OBD).
