You should hear a beep from your alarm sounder (either a horn sound or a alarm tone if you have the BBUS alarm system when you lock the car as it's alerting you that it thinks either the boot or tailgate is open.
Annoyingly the IPK doesn't specify if it is the bonnet or the tailgate it thinks is open, but normally it's the bonnet as the bonnet switch gets water in it and stops working.
The only common cause of battery drain I can think of is if you have the highline sat nav head unit system the satnav drive in the boot not powering down when you switch off the car is a common issue. The drive will just stay on permanently spinning the disk, which is enough to drain the battery in a few days. I've come across electrics getting wet causing battery drain before as well.
Also check the condition of your battery, as I had one once that would no longer hold a charge very well, so although it would show 12v after charging, it would dump all the charge out overnight.

thanks Rick-sta for your reply if i disconnect the battery it lasts for a few weeks but left connected it only lasts a few days i had been leaving the bonnet just closed in the first position without fully closing which i thought could be the drain but when closing fully it is still draining i will certainly be looking into the sat nav thanks again
