I plan to replace the battery in our '06 530Xi in a couple of weeks. Is there any specific step by step I should follow, and will I have to then bring it to a dealer to re-sync the battery, or can I do it myself? Thanx in a advance for any advice anyone can offer. BTW, replacing OME 570 CCA battery with Interstate 770 CCA battery.
It's called BATTERY REGISTRATION and it's explained in the following thread http://bmwcca.org/forum/showthread.php?t=7039&highlight=battery+registration
