You may recall that I had that plugged drain under the battery tray of my 240D a while back. I've been cleaning up the area under there, getting ready to POR the rusty areas, and I found this rubber piece mixed in with the rusty chips of the old battery tray. Any idea of what it is?

The small metal pieces on the paper towel are the last remnant of the washer nut that was holding the bottom of the tray to the fender, by the way; when I went to work on it with the Dremel it was just an unrecognizable lump of rust! I'm getting better at dealing with these.
