Service bulletins for the 2016 BMW 340i

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.

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

B1221142018-11-05. Service bulletin. FUEL SYSTEM, OTHER:STORAGE:FUEL GAUGE SYSTEM; ELECTRICAL SYSTEM:SOFTWARE; FUEL SYSTEM, GASOLINE. Engine Malfunction Warning Illuminated with FC 193208: Fuel Level Plausibility Stored in DME. The customer states that the engine malfunction warning lamp is illuminated, and while filling the fuel tank, the fuel gauge did not show the proper fill level. After the vehicle is driven a short distance, the fuel gauge will update to full. When diagnosed, the following fault is stored in the DME: ? FC 193208 Fuel level, plausibility: deviation between consumption and level change Please proceed to the Procedure section. Vehicles with option 610 (Head-Up Display) are not affected. Please follow the ISTA/D test plan for the applicable faults stored in the DME, including the one listed in this bulletin. CAUSE A software error in the instrument cluster causes the fuel gauge to incorrectly update while refilling. The error occurs when the vehicle is powered up after refilling.
B6103142018-11-05. 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 occur. 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 shutting down certain electrical consumers.
