the 9v battery "memory holder" does work for the clock settings, and is extremely important in volkswagons as they don't keep the memory in the engine computer.... go volkswagon! But as many batteries as I have changed over the years, I've NEVER had one lose key remote function, and also never had a vehicle go back into transport mode... weird. And transport mode is what the vehicle is put in for shipping overseas and transport to the individual dealer when spanking new with no miles, and is turned off during the pre-delivery check. What it is is all the unnecessary computers and functions are turned off to keep the battery from going down during transport.

But that is not what needs to be done with a new control module. The control modules in BMW's are encoded with vehicle information like vin# etc, and are programmed with updated software versions to fix small bugs and adjust how certain things work. So they are not plug and play, and you have to go in the programming computer, which is a different beast from the diagnostic computer, and mark the control module as replaced. Then the SSS (software service station) will create a "measures plan" and perform all necessary encoding and software adjustments.
