Hi there papperbear
I think you need stronger glasses; D No only joking
The screws are hard to find, but they are inside the handles where you can pull the boot lid down. (I can't remember if there are normal screws or the funny star shaped ones)
Then in order to pull the panel out you need to pull hard (Don't be scared to do this they are on some strong clips)
Then you can root around for that annoying rattling sound (I had the same problem)
