    Replacing battery in '03 530i

    I have a new OEM battery for my wife's '03 530i sitting in the trunk of my car. Are there any special gotchas when I repalce it tonight. After 7.5 years,the present battery is just barely alive and won't start the car more that once after a drive, recharge, or if it has been sitting for a day or so.

    I assume I'll have to reset the clock & other OBC stuff. Anything else?

    Clock and your trip miles are about the only (m)

    things that will be gone. Before you disconnect the old battery open the trunk and wait for the trunk light to go out, 16 min. This will ensure that all of the modules have "gone to sleep." Then disconnect your old battery.
    Now if your old battery is dead and the trunk light doesn't come on then it really doesn't matter.

    make sure you hook up vent tube

    you can't see it from top of better. but as you remove old battery you will see connection at end of the battery facing forward.
