After retrieving the pin, I cleaned it off, pushed it back into the flap, and reinstalled the DISA unit.

Since the DISA unit slides into a channel between the two halves of the intake manifold, I have my doubts that the pin would even be able to get loose in there and do a tap-dance inside one of the cylinders - but I'd like to hear from someone who has studied the system more thoroughly.
someone posted that exact thing happening to him. I don't remember if it was here or e46fantatics. my pin slide in and out fairly easily so I'm sure given enough vibration and time it could have come out completely.

in my case I had to replace the disa as it was completely worn.
