This coverage applies to the specific vehicle (VIN), the remaining portion of the ELW is transferrable to each
subsequent owner, and it is subject to the same vehicle eligibility requirements, limitations, and exclusion
criteria that applies to the BMW New Vehicle Limited Warranty for Passenger Cars and Light Trucks.
Note: This bulletin is notice of a limited 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.

CAUSE
The vehicle’s Telematics Control Unit’s Internal Emergency (Backup) Battery may not meet BMW’s operational
standards because it may have faulty cells and/or its overall performance in varying outside temperature
conditions may be less than what is optimally required.
Should a situation like this occur, it may affect the operation of the vehicle’s Telematics system. If that should
happen, the vehicle’s monitoring system will generate and show the corresponding Check Control Messages
(CCM) in the vehicle’s display, for example:
Emergency system fault

CORRECTION
Follow the instructions in the PROCEDURE section.

PROCEDURE

(Backup) battery.
