Start up sound
Just noticed an odd sound that I only hear on initial start up..... best way to describe it is if you threw a small pebble at a tin can. I hear 2 or 3 of these sounds and from there it sounds fine... any ideas?

It's the valves in the exhaust rattling. Did it on both of our F80s and does it on my F87 as well.
