General notes

WARNING: This page is about a different car, the 2013 BMW X5, 2012 BMW X5, and 2011 BMW X5. However, it is still accessible from the selected car via links, so may be relevant.

If the TCB control unit is programmed or the control unit has to be replaced, the online services have to be subsequently updated. This generally happens automatically via the programming system. It is possible to check this by selecting online services from the menu in the central information display.

A service function is available for updating the online services. This can be found as follows:

Service functions > 03 Body > Telecommunications or headunit > Online service update
