Battery Drain Even After Seats Unplugged

I, like many others, have the faulty seat modules in my C320 Wagon. I've unplugged both seats (as inconvenient as it is not to have operable seats)...yet I am still having a battery drain if the car isn't started up after a few days.
Is unplugging the seats not enough to stop the drain...or could it be something else that's now draining. What is another common reason for battery drain?
Thanks in advance for your reply..this is my first post.
