Greetings! I'm a new member and hope this question can be asked here. I have a 2009 S60. I've noticed that the outside trim over the rear doors has a section missing and there's a weird piece of metal there (which appears to have started to rust). What is that?

Sorry. I moved this question to the S60 section, so disregard unless you want to answer from here. In the S60 area I added a photo. My apologies. Anyway, I appreciate the forum being here for assistance.
