It did - it was a 13 plate so that might be a later mark.
I would try removing the fuse from the interior panel if you haven't already.
If you have a multimeter you can connect it between the negative lead and the battery and look for the presence of a draw (there a lots of Youtube vids on doing this) - and then remove/replace the fuses one by one to see if the drain stops. For me it was the 10a red fuse - which was the Blue&Me as well as the radio etc.
