B6103142018-11-05. Service bulletin. ELECTRICAL SYSTEM. Check Control Messages Related to Battery Charge During Cold Ambient Temperatures. On cold days with an outside ambient temperature of less than 15°F, customers may notice a check control message related to the battery that is displayed on the instrument cluster and the control information display. Under these conditions, the vehicle starts. Various power management faults can occur. The check control message (ID 229) is caused by a heavily discharged battery. ? The check control message is triggered when the current state of charge (SoC) of the battery approaches the minimum SoC that is required to start the vehicle (start capability limit). ? In low outside ambient temperatures, the start capability limit of the vehicle is higher. Therefore it takes more energy from the battery to start a cold engine. ? Without the early warning of the check control message, the current state of charge would drop below the start capability limit and the vehicle would not start. ? The vehicle's intelligent power management system actively takes measures to increase the charge of the battery, such as increasing idle speed and reducing or shutting down certain electrical consumers.
B3602152018-11-05. Service bulletin. TIRES:VALVE; WHEELS. Valve Stem Replacement with Wheel Electronics. INFORMATION The valve stems are single-use only, and must be replaced every time the wheel electronics are replaced. If you loosen the nut (1), you must replace the valve stem.

They should be completed only based on parts availability, workshop capacity, and the customer's schedule. Performing the test plans identified in the procedure below will detect wear at an early stage and, if necessary, provide a repair solution. To avoid future valvetrain wear, the vehicle must be reprogrammed and a shorter oil service interval must be retrofitted via ISTA/P. Finally, drain and replace the engine's oil and filter. After completing all necessary repairs included in the N63 Customer Care Package and the Timing Chain Check, the vehicle must be test driven for up to 30 minutes to ensure that the repairs were performed to the highest standard."
