Annoying rattle fixed.
Ever since I picked up a cpo 2010 e550, it had this plastic tapping noise coming from rear whenever it sat in the sun for a while. I bought a very good quality felt tape and taped suspected areas with no result. I even tried pulling c-pillar panel a few times but did not have the heart to pull it competely out until today. When I pulled it out all the way (disconnecting it from rear sunshade in the process), it was obvious that white plastic screw that connected the panel to the body was loose. With a little bit of crazy glue, the cabin is finally dead silent for the first time and I am in love with the car all over again.
