Service bulletins for the 2014 BMW 328i

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.

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

6502132018-11-26. Service bulletin. EQUIPMENT; EQUIPMENT:ELECTRICAL:RADIO/TAPE DECK/CD ETC.. Headunit-Basic Does Not Start Up and "BMW" Is Permanently Displayed. The Headunit-Basic (HU-B), also called Radio Professional or the ENTRY head unit, does not start up and "BMW" is permanently displayed on the CID (Central Information Display). No fault code is stored in the head unit. Hardware issue in the HU-B
6201132018-11-26. Service bulletin. ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL. All Gauges and Displays in Instrument Cluster Inoperative. All gauges and displays in the instrument cluster are inoperative, including the following: * Speedometer * Revolution counter * Fuel gauge * Engine oil temperature * No check control messages displayed ??No board computer information displayed Note: A power cycle does NOT rectify the issue. Software error in the instrument cluster
3401132018-11-26. Service bulletin. SERVICE BRAKES. MErroneous "Service due" Message Though Brake Lining Thickness Sufficient. The CBS data calculated for the remaining distance of the front and/or rear brake pads does not agree with the actual brake pad thickness. The yellow brake lining service due indicator illuminates even though the pad thickness is greater than the minimum wear limit (approximately 3.7 mm); the brake wear sensor has not yet been activated (from a thickness of approx. 4.2 mm). In some cases, the red warning message may already be active. The CBS front/rear brake display is based on a mathematical calculation. Various influences are incorporated into this calculation (for example, vehicle speed, brake pressure, and rotor temperature). Due to changing driving characteristics and/or unfavorable environmental conditions, the calculated remaining distance may differ from actual pad thickness.

After programming the vehicle with ISTA/P 2.47.1, unlocking the trunk with the remote changes to unlocking all the doors. An application error occurred after programming the vehicle to the Personal Profile Setting (PIA) in the Front Electronic Module (FEM).
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
5131142018-11-13. Service bulletin. EXTERIOR LIGHTING:HEADLIGHTS. Headlight Cleaning System: Functional Operation Change. The customer complains that the headlight cleaning system is not working properly and only works after several actuating attempts. CAUSE The "functional" operation of the headlight cleaning system was changed with integration level F020-14-07-500. The functional changes to the headlight cleaning system's operation will occur only after programming the vehicle with ISTA/P 2.53.0 or higher. INFORMATION The headlight cleaning system is no longer activated with the first stalk activation when the lights are on. The functional programming change now requires the stalk to be activated four times before headlight cleaning is activated. The change prevents automatic activation of headlight cleaning when the customer only wants to clean his/her windshield. This is normal operation and no parts should be changed.
7102142018-11-13. Service bulletin. ENGINE AND ENGINE COOLING:ENGINE:DIESEL; EQUIPMENT:OTHER:LABELS. Service Action: Replace Emission Label. Certain 2015 model year vehicles with N47T and N57T diesel engines were produced with an "emissions" label which contains incorrect information pertaining to the 2015 model year. Affected vehicles in dealer inventory must not be retailed or delivered until this issue is corrected. Vehicles at VDCs will be repaired prior to dealer delivery.
6516142018-11-13. Service bulletin. EQUIPMENT:ELECTRICAL. Central Information Display Intermittently Dimming or Flashing Off/On. Intermittently the Central Information Display (CID) dims and/or flashes off/on. There are two possible root causes for this issue. Cause 1: 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 Cause 2: Calibration data for dimming the Central Information Display (CID) at high temperatures or bright sunlight is set incorrectly internally in the CID.
6406132018-11-13. Service bulletin. EQUIPMENT:APPLIANCE:AIR CONDITIONER. A/C Cooling: Intermittent Reduction of Air Flow. The customer may complain of reduced air flow when the air conditioning system is operated for an extended time, usually longer than one hour. The complaint can vary due to one or more of the following variables: * High outside ambient temperature * Too much humidity * A/C temperature and fan settings set too low for too long Note: It is very difficult to duplicate this issue due the required outdoor weather conditions and length of driving time needed. CAUSE Evaporator starts to freeze up due to the position of the evaporator temperature sensor.
