If you have a multimeter, place it across the battery terminals and check the voltage. If it's below 10.5V, then there is a drain on it. Pull all auxilery fuses (lights, heaters, windows, wipers....). Measure the voltage all of the time while you do this, and if it jumps up to about 12V, then you may have found the drain. It will need a jump start. Replace fuses once it's up and running, ensuring that all switches are off before doing so... Hope this helps. It worked for me on a Xantia where there owner's lights were left on, but the battery was too low to light them so that we could see them in daylight.
