7 Series - E65 / E66 (2002 - 2008)
Discussion of BMW's 4th generation E65/E66 7 Series flagship. The E65 generated much controversy, due to its radical styling and iDrive user difficulties. Nonetheless, the E65 broke records to become the best-selling 7-series iteration ever, especially after its 2005 facelift.

Reprogram power module so it supports 90AGM.

I'm looking for some information on an easy way to reprogram my power module so it supports 90AGM. I have a 2002 E65 and have been doing research and found this.
This article seams to apply to my vehicle, I replaced the battery with a 90ah and need to reprogram the control module, has anyone done this and if so got any pointers on how I can possible successfully perform the reprogram? Any help will do, thanks in advance!

You need to use NCSExpert, ISTA/D or ISTA/P to reprogram the car to recognize the 90ahm AGM battery.
