I have a 2000 323ci; when I leave the car unlocked, the interior lights remain on--if i don't lock the car. This seems strange to me (and caused the battery to die yesterday). I can turn off all the interior lights by pressing/holding the main interior light button for 3 seconds, but that seems drastic. Also, when I got the car jumped, the digital odometer read 5k miles less! Any experience with this? Suggestions? Thanks.
