The little clicks are normal when the battery is low, but I think what is happening is the car is no going into "sleep mode" because of a bad BCM which is common but to be sure let's do a CAN scan which is easy to do. You can get a CAN scanner from Amazon for about $30.00.
Here is a video to show you how:
Here is how to replace the BCM in case you need it in the images below. You can find a rebuilt BCM if you search Google, have your VIN number ready for reprogramming. The export (euro) is one the left side btw. Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.
