OK, here's the cliff notes as it's late.
I set out to tackle replacing the distributor, saving myself a 2.5hr
round trip to my local Audi specialist.
I set the engine at TDC, indicated by the 0 in the (tiny) window above
the transmission. I did this by having the car on a slight downhill, in
5th gear, and a helper on/off the brake as I literally hovered over the
hood trying to see in.
Once at 0, I removed the distributor by first chiseling off the
protective cover and bolt, removed the 13mm nut and "yoke" holding the
dist on. I then verified that the gear was only slightly worn, but the
dist had considerable play in it, compared to new.
I lined up the rotor, hash mark on the round piece below it, and the

I'm not sure what all this means. Could it be that the engine was
already 180 degrees off, and my rotation just compensated for this? Or,
am I the one who is off? I'm not sure if I should leave it like this or
have it checked out, you tell me.
I didn't even tighten the nut yet, but will do so tomorrow.
