David,

My daily driver is the slower cousin of your M3 - I have a 328Ci. One wonderful day while dodging potholes on I10 in Louisiana I happened to not miss the lovely remains of one rather dead semi truck tire (I am from Lousiana originally, it is my right to clearly state that their interstates stink). It tore up the under body plastic covers on my car rather nicely. I had a vibration similar to what you describe. Have BMW make sure all your underbody pins are installed and have them lock tite them all. Another possibility is something like an acorn or something may have made its way onto and/or around your front shock towers or on top of the lower pans.

While awaiting my car to be fixed a family of squirrels moved into my engine bay and stored their summer stash behind the shock towers. Talk about make some noise (the nuts...not the squirrels).

When I had the car fixed all the nuts were knocked out and fell onto the lower cover. The car sounded like a chinese checkers board in flight. It was quite comical now that I think about it...at the time it was quite frustrating.
