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.

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.

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.
B5115152018-11-05. Service bulletin. STRUCTURE; EQUIPMENT. Removal Process: B-Pillar High Gloss Trim Protective Wrap. INFORMATION ONLY The key for successful wrap removal is to have the body cool (below 60 degrees) and dry. The recommendations are as follows: ? Before removing the B-pillar wrap, make sure the car body is dry and cool. ? Removing the wrap in the early morning hours will provide the best results. ? In warmer climates, it is recommended to keep the cars in an A/C environment at least overnight, and then, in the morning, slowly peel off the wrap. ? If there is still any glue residue left, use masking tape to cover the glue area. Wait for a few minutes, and then pull off the masking tape. Repeat this process until the glue is fully removed.
