SITUATION BMW AG is conducting a Voluntary Emissions Recall (effective April 23, 2021) on a certain Model Year 2020 - 2021 BMW vehicles that were produced between August 13, 2019 and December 11, 2020. Do not deliver to a customer, a New, Certified Pre-Owned or Used vehicle subject to an emissions recall, until the vehicle is repaired. Do not use or sell replacement equipment/parts subject to an emissions recall. The 12 V batteryâÂÂs dual storage system (DSS) may contain a software error which intermittently causes a continuous resetting of the microcontroller and communication failure. The error is displayed by a red Check Control message.

An interference noise (groaning noise) can be heard from within the heating and air-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.

The 3G network in the US has been shut down. This means that only the 4G network will be available. In the 4G network, voice calls will be transferred via the Voice over LTE (VoLTE) function. For this purpose, the SIM card must perform an IMS registration in the mobile communication network. Due to a production error, the telematics control units were delivered without an IMS configuration. The Connected Drive voice services (Concierge Call, BMW Assistance, and emergency call voice) can no longer be used regionally in the US in vehicle with telematics control units ATM-1 and TCB-4G. Voice control of the vehicle and all other telephone (paired mobile devices) functions are not affected. Emergency call location data is unaffected.

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.
