B0109192023-01-30. Service bulletin. FUEL SYSTEM, GASOLINE. For the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the vehicle's Fuel Injectors to 10 years/120,000 miles as determined by the vehicle's original in-service date.
B1701212022-06-21. Service bulletin. ENGINE AND ENGINE COOLING; FUEL SYSTEM, GASOLINE. The quick disconnect coupling on the cylinder head coolant vent line could break at the cylinder head. This would lead to loss of coolant from the engine.
B1701212022-05-31. Service bulletin. FUEL SYSTEM, GASOLINE; ENGINE AND ENGINE COOLING. The quick disconnect coupling on the cylinder head coolant vent line could break at the cylinder head. This would lead to loss of coolant from the engine.
B0107222022-05-31. Service bulletin. FUEL SYSTEM, GASOLINE; EXTERIOR LIGHTING. 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.
B1603192019-06-24. Service bulletin. FUEL SYSTEM, GASOLINE. NOISES FROM THE FUEL TANK AT IDLE AND WITH LOW FUEL LEVEL. While driving slowly with low RPM or while idling a faint knocking or fluttering noise can be heard from inside the fuel tank. The customer may describe this noise as a "helicopter" noise from the rear of the vehicle.
B1601192019-02-25. Service bulletin. ENGINE AND ENGINE COOLING:EXHAUST SYSTEM; FUEL SYSTEM, GASOLINE:DELIVERY:FUEL PUMP. ENGINE STALLS AFTER STARTING OR WILL NOT START. The engine stalls right after starting (when stationary).

1304092018-11-26. Service bulletin. ENGINE; FUEL SYSTEM, GASOLINE. "N54 Engine: Diagnosis of Cold Start Rough Running with Misfire Faults. The customer may complain that during the cold start in the morning, the engine runs very roughly and the Service Engine Soon lamp is illuminated. Various misfire fault codes (e.g., 29CC, 29D2, 29D1, 29D0, 29C0, 29CF) may be stored in the DME control module. The engine rough running complaint can be reproduced on a cold start in the workshop. During the course of diagnosis, the spark plugs, removed from the misfiring cylinders after the problem was reproduced, are found to be soaked (""wet"") with fuel, while the injector tips are covered with a layer of carbon deposit. Possible cause: high-pressure injector failure (leakage or incorrect spraying pattern) due to internal wear or unfavorable stock of tolerances IMPORTANT: For comprehensive N54 drivability diagnostics, always refer to the ""N54 Engine Diagnostic Fault Tree"" file (the current version ""02_14_13"" is found as a PDF attachment to SI B12 55 06)."
