Good point on the battery, I had just the front open and everytime I opened/closed the back doors all the lights came on, so I started leaving all of it open and eventually it slept (15 minutes maybe?). I know it is very sensitive to have excess draw while off. The car has complained to me in the past.
I'll just pull the sill. I'm almost 100% positive that I have spare clips from my MINI install. Thus far the door panel clips for BMW and MINI have been identical.
