I'm doing a timing belt job on my '01 TT using BlueTTop's guide. I'm to the point of lining up top dead center. (TDC)
TDC is lined up perfect just like in the photo below, but the TDC is not exactly in the center of the fly wheel (unlike picture 2) The mark on my fly wheel is rotated back toward the firewall just a bit. I've not yet removed the timing belt, and to my knowledge its never been done on this car (58k miles). Aside from counting the teeth, is there anything else I should do? Should I be concerned that the TDC mark isn't exactly in the center of the sight hole to the fly wheel?

If it's less than one tooth I wouldn't worry about it.
The belts stretch and the tensioner gets weak over time. It's rarely perfect and once the new belt and tensioner go on it may be slightly different again.
