Here's the end result.
The serpentine belt was installed wrong when I had the timing belt
changed. It was rubbing on something causing the engine noise. As far
as the synthetic oil, the 2.7t calls for synthetic 5w40 but I was
unable to get that locally so I was using a heavier synthetic. The car
no longer smokes but it has not gotten as cold since that morning
either. Live and learn I guess. The plus is I have found a local
mechanic who works on Audis and is honest.
