    I bought a brand new battery for my S3 on Christmas Eve as the old one had died,I had to do some work on the car last Saturday so it had been stuck on the drive up until last night,I had left it unlocked all week and on Thursday I started it up and it started fine and I left it running for 10mins or so,once I had finished I then locked the car,I went out to the car last night just to finish off the last few bits and it unlocked fine but I went to try and start the car and the battery was flat for some reason,any ideas what might have caused the sudden battery drain

    Just check that none of the lights are ledt on inside or the boot...also check your alarm isnt being triggered.

    Also see if you can check with a multimeter if there is a drain anywhere.
