SummaryComponent 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.
