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.

NHTSA's summary

N51 Engine: Service Engine Soon Lamp Illuminated - Loss of Power and Various Faults Stored in the DME. The customer complains that the Service Engine Soon lamp is illuminated. The vehicle has lost power; the engine cranks but will not start; and various faults are stored in the DME for engine misfire and/or mixture adaptations. CAUSE The vehicle has lost fuel system delivery pressure due to a loose or split fuel line inside the fuel tank. The failure is related to an unfavorable stacking of tolerances between the rubber fuel hose and the plastic regulator nipple or deterioration of the rubber hose construction material.

B0107222022-05-31. Service bulletin. Component and Issue Specific Limited Emission Warranty Extension. This bulletin is notice of a limited emission warranty extension. This is NOT a notice of a Recall or Service Action. There is no immediate repair required unless the BMW vehicle is currently experiencing this problem. Customer Notification Letter Even though this is NOT a Recall, BMW NA is sending VIN-specific customer notification letters. The plastic fuel tank has two openings, one at the top right and the other at the top left. The top right opening (passenger's side, serviceable) provides a mounting point and repair access to the intake fuel pump/level sensor assembly. The top left opening (driver's side, non-serviceable) serves as an access point for the installation of the suction jet pump/level sensor assembly during the fuel tank manufacturing process. After these components are installed, the top left side opening is then permanently closed and sealed with the installation of a circular Coex biopolymer plastic cover plate which is welded into place. Over time, the left side opening plastic cover plate weld may become damaged. Should this occur, there is the possibility of fuel leakage. Additionally, your vehicle will store the corresponding fault codes that may also be generated, and the Malfunction Indicator Lamp (MIL) will illuminate.
