I changed out the pollen filters and dropped a round metal nut that holds the pollen filter cover in place, it is on the opposite side of the clip and about the size and shape of a nickel. I've searched but I cannot locate the part number. Thanks for the help.

Here is the part number I believe: 900 241 003 02 -- knurled nut -- quantity needed 2 (1 each side)

I had an extra one, but already gave it to a rennlister who did exactly what you did!
Sorry I couldn't be of any help.

That's it!! Thanks linen gray ghost and nine9six!

Depending on where you dropped the nut (i.e. not into the HVAC ducting), it might be worth crawling under the car and removing the fuel pump cover, dropped fasteners have a habit of ending up there!
