// Battery. Electrostatic discharge at standstill / start engine. Energy management" The results of the Energy Diagnosis test plan identifies the Controller as the root cause of the CCM. The Controller delays the vehicle going to sleep by up to 6 minutes. In some cases this will cause the CCM 415 to be displayed when starting the vehicle. Replacing the Controller in this case will not correct this situation.

ConnectedDrive/BMW Assist features are partially or completely inoperative. This Service Information Bulletin: Is being published because vehicles are down for an extended period of time when researching system failures with ConnectedDrive or BMW Assist. Will assist you both in identifying the issue and providing technical support. CAUSE Not enough information is available for BMW NA engineers to assist the technician in diagnosing the root cause.

The vehicle will run rough or hesitate when accelerating from a stationary position.

The Service Engine Soon light is on. There may also be a complaint of low heat output with lower outside temperatures. CAUSE During the engine warm-up the engine coolant does not reach operating temperature within the DME's allowable time limits. This is caused by either a faulty thermostat inside the transmission oil heat exchanger or a faulty engine characteristic map thermostat.

On rare occasions during an engine oil service the BMW Original (Genuine) engine oil filter insert is either difficult to remove or breaks apart in the oil filter housing. The engine oil filter is broken. The paper is torn and the lower plastic section is stuck in the engine oil filter housing (1).

The INITIAL NAV enabling code no longer needs to be pre-ordered through the Parts department! When the vehicle is connected to the diagnostic system ISTA to perform PDI/QC1 the step to activate the navigation system (part of Delete Transport Mode) will automatically request the INITIAL NAV enabling code (VIN-specific) without pre-ordering the enabling code. This enabling code will be automatically delivered through ISTA and it then activates the navigation system.

For the eligible vehicles, BMW of North America, LLC (BMW NA) is extending the limited warranty for the vehicle Nitrogen Oxide (NOx) Sensor(s) to: 10 years/120,000 miles as determined by the vehicle original in-service date.

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.

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.
