I'm taking it in in a few days to work a separate issue and I'll report back if BMW has any fixes (although I'm sure they're going to align with the notion of it being within "within spec").
Any luck with the dealer, Kaneda215?

As a side note, I have noticed that the knocking has somewhat lessened in intensity now that I've driven the car about 2,500 miles. It will still knock as the tank gets below 1/8 of a tank but it's not very loud and will sometimes not happened at all. I'm not sure it is because of the colder weather her in the Northeast.
