Bulletin Summary
F30 AND G12 PHEV FUEL TANK PRESSURE SENSOR LTD WTY EXT TO 15 YEARS/150000 MILES. PHEV Special Requirement and Operation The PHEV fuel tanks are designed for the special requirements that arise from the hybrid operation for example operation of the vehicle alternates between the combustion engine and the electric motor. As a result excess pressure can build up due to the gasoline vapors this excess tank pressure must be dissipated before the fuel filler cap is opened. As outlined in the Refueling Procedure attachments the vehicle's operator performs a pressure equalization procedure to address the above situation. After this procedure is completed only then can the fuel filler flap (door) be opened to access and remove the fuel cap for refueling. Possible Concerns Even though the pressure equalization procedure has been performed/completed the fuel filler flap (door) still cannot be opened and/or related fuel tank readiness indicator (code) does not reset. The fuel tank pressure sensor may have failed and this could be the cause.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
