Service bulletins for the 2014 BMW 328d

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.

501 on file from NHTSA, as of 2026-10-19.

B6130172018-11-26. Service bulletin. ELECTRICAL SYSTEM. RAIN/LIGHT SENSOR (RLS): OIL LEAKAGE FROM GEL PAD. ??Oil leaking from the Rain/Light Sensor (RLS). Note: This oil serves as a separation medium between the RLS mounting gel pad and the windscreen. The oil ensures damage free disassembly in case of repair. CAUSE The oil that serves as the separation medium of the Rain/Light Sensor (RLS) gel pad and the windscreen leaks out. Expose the Rain/Light Sensor (RLS) and properly clean the area of all oily residue. Note: The separating oil usually leaks only once from the pad at the RLS. Due to the small oil quantity in the gel pad, additional oil leakage is not plausible. Leaking oil does not impair the function of the RLS.
6602132018-11-26. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT:ELECTRICAL. Rear-view Camera Does Not Turn On Automatically. When the reverse gear is selected, the rear-view camera does not turn on automatically. The driver must activate the rear-view camera using the iDrive controller or the camera button. CAUSE Software error in the Front Electronics Module (FEM)
6102112018-11-26. Service bulletin. ELECTRICAL SYSTEM. Advanced Onboard Battery Diagnostics. Starting with the introduction of the F10 (5 Series), an advanced intelligent battery sensor has been used. This now makes it possible for the vehicle to monitor the condition of the battery in order to determine if the battery needs to be recharged or replaced, along with the remaining capacity of the battery. The analysis and testing of the battery's SoC (Stateof Charge) and SoH (State of Health) is now performed using ISTA (Integrated Service Technical Application) diagnosis. A separate test using a battery tester is no longer needed.

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

6523142018-11-13. Service bulletin. ELECTRICAL SYSTEM; EQUIPMENT ADAPTIVE/MOBILITY. Central Information Display Intermittently Flashes Off/On. Intermittently, the Central Information Display (CID) flashes off/on. Voltage supply error from the Headunit-high (HU-H) to the Central Information Display (CID) when the display brightness is set to 60% or higher.
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.
