i mean has anyone actually tried replacing their battery and documented a failure because they did not re-program their battery?
i would think that the system cant be so failure prone because if it is, wont this be a major liability issue? i am sure there are tons of people out there with regular 1,3 or 5 series that are already out of warranty and just go to a plain old indy shop or canadian tire, etc to replace the battery. i am sure canadian tire doesnt have the 'speciality' tool needed to reset BMWs.
Every which way you look at this coding thing, it is simply dumb/stupid if indeed it is required. Injectors perhaps (even then) but batteries?
