Bmw e46 330d battery replacement using only the cars own tool kit Same process for other BMWs (E39/E38/E46) Same process for newer models too such as E90, but they can require the battery resetting in diagnostics.
do you need to tell the car you have fitted a new battery to prevent the '' smart charge system '' from overcharging the battery and destroying the new one in a few weeks or less ??
