WARNING: This page does not describe the selected car, but rather 333 other vehicles, including the 2007 BMW Z4, 2007 BMW X5, 2007 BMW X3, 2007 BMW M6, and 2007 BMW M5. However, it is still accessible from the selected car via links, so may be relevant.
The program and or data of an engine or transmission control module only needs to be updated or replaced if:
- The control module is replaced with a non programmed/basic module.
- A Service Action, Recall or customer concerns have resulted in the release of a new/updated program or revised operational data.
The programming procedure of the diagnostic equipment will identify if:
- a DME EPROM needs to be replaced or can be updated
- a control module (DME or Transmission) can still be programmed or needs to be replaced if the reprogramming limit of 13 times has been reached
