SI B01 18 24 (RC 84 10 90 03 00): For this vehicle, the Telematics Control Units (TCU)
Internal Emergency (Backup) Battery for defects in materials and/or workmanship has been
extended to 6 years without mileage limitation, as determined from the vehicles original first
in-service / delivery date. This coverage is subject to the same vehicle eligibility
requirements, limitations, and exclusions that apply to the BMW New Vehicle Limited
Warranty.
Note: Before performing a repair and submitting a claim, first confirm that the vehicle has the above Notice of
Extended Limited Warranty coverage in the WVI “Vehicle Comments” section.
If you have ELW eligibility and/or coverage questions, please contact the Warranty department through IDS by
selecting Coverage, Policy, Coding Questions and Mileage Corrections prior to performing any repair.

SITUATION
Component-Specific Extended Limited Warranty (ELW)
For the eligible vehicles, BMW of North
America, LLC (BMW NA) is extending the
coverage for the vehicle’s Telematics Control
Unit’s (TCU) Emergency (Backup)
Battery (Item # 1) to:
6 years without mileage limitation, as
determined from the vehicle’s original inservice / first delivery date.
This component-specific extended limited warranty
coverage applies to defects in materials or
workmanship.

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.
