Tip & How-To about BMW Vehicle Parts & Accessories
Make sure you hook a battery charger to the posts under the hood before you change out your battery. Otherwise the car loses all data, has to be flashed, recoded for the new aftermarket battery if that's what you bought and re-registered to the car. Believe me, it's much cheaper just to have the dealer install a new one. This is not all BMW's but some of them require this attention.
