SITUATION
The Non-Volatile Memory (NVM) within the Network Access Device (NAD) may have been corrupted. This may cause the manual and automatic emergency call and roadside call (BMW Assist(R)) to malfunction. This Service Action checks the integrity of the NAD and if found to be corrupted, corrects it by a special programming repair or by TCU replacement.
Copies of the customer notification letter and Q&A are in this bulletin.
To minimize the customer's inconvenience caused by this service action, pick up (and deliver after repair) the affected vehicle from the customer's home or provide appropriate alternative transportation.
Customers will be impressed when you return their cars cleaned inside and out and with a full tank of gas. Reimbursement information for the vehicle fueling and valet costs may be found in the Warranty portion of this bulletin.
