Same with my 2001 - The dealer charges something like $100+ to reset it. You can buy a resetting device to plug-and-play (there's a port under the driver's side dash to connect with) for $150 or so. I just left the damn thing on. I don't know why it's on but I'm not going to pay to fix it. Since it's only a few days since purchase I think you should bring it back to the seller and insist they fix it. Good luck!
