Just noticed that there is a rectangular plastic "hole plug" in the heel area of the right rear passenger seat (in the carpeted area). Before my curiosity gets the best of me and I mess with something I shouldn't, what is this for?

Now you've got me wondering, too!
It may be used to access the battery. My '98 E430 has the same plug.
Maybe Benzmac will enlighten us.

The plug covers the attachment point for the battery Ground cable!! Have found several loose & causing strange problems, somewhat a small bolt so don't over tighten!
