Don't want to scare you but hears the story on my 04 W900. Cat said I needed to update software or my warranty would be void so I did, truck ran like crap so I talked my mechanic into putting old software back in but he told me if I ever changed batteries truck may not start. Couple years down the road I forgot what he told me and changed the batteries, truck would not start cuz it fried the computer when it lost power. Very expensive lesson.
