INFORMATION

SITUATION

Installing a Telematics Control Unit (TCU) from a known good vehicle into a problem vehicle is acceptable for testing purposes only.

Precautions:

^ [NEW] Swapping TCUs for testing purposes must only be performed when recommended by Technical Support via PuMA.

^ The vehicles must have the same production range, e.g., do not install a pre - 3/08 TCU into a post - 3/08 production vehicle.

^ The vehicle must have the same TCU type, e.g., Code Division Multiple Access (CDMA), Global System for Mobile (GSM), I/K-Bus, etc.

^ The vehicles must be similarly equipped, e.g., if the problem vehicle is equipped with a navigation system, the known good vehicle must be

equipped with a navigation system.

^ [NEW] Do NOT program or code the test TCU to the donor vehicle.

^ NEW] The TCU from the known good vehicle must be reinstalled in the original vehicle after testing has been completed.

[NEW] NOTE: This step is very important and it must be completed!

[NEW] After reinstalling the test TCU in the original vehicle from which it was borrowed, a BMW Assist test call must be performed.

The relationship between the Electronic Serial Number (ESN) or the International Mobile Equipment Identity (IMEI) in the TCU and the Vehicle

Identification Number (VIN) must always be maintained.

BMW of North America LLC deactivates the cellular services for the Network Access Device (NAD) within the TCU when the BMW Assist

subscriber agreement expires.
