Charge the battery, get a meter, set it to amps, then disconnect the negative battery terminal. Put one probe on the battery terminal, and one on your negative cable. Anything more than .5 amps and you'll kill the battery after that amount of time. Leave the meter hooked up and start pulling fuses one by one, checking each time until your amp draw comes down to an acceptable level. Look at which fuse you pulled, and start checking the components on that circuit. I'd get a wiring diagram too, because sometimes they put more things on a circuit than just what is listed on the fuse panel.

This is all with the key off... The half amp or so will be the memory for the computer and your radio...

If it checks out, you maybe left the hatch open or the dome light on or something.

Oh yeah, security system too... so as long as its below 1 amp, you're probably fine. Two weeks IS a long time, as you do have all those things running with the key off... If you leave it sit for that long, you should probably get one of those batttery tenders. I had a Jaguar that would kill the battery if you let it sit for a week. If you drove it every day, you never had a problem...
