Well, unfortunately i think they are both "016" but I may be wrong.
This should be lightly embossed in the top of the flywheel housing area,
try cleaning it up a bit to find it.

You can always check the old fashioned way... count input turns versus
output turns.  This works best when you have one of each on hand to
compare, of course.  These are what I have in a spreadsheet for the
higher geared, 85-87 box (I think Audi tried to keep the lower gear
ratios secret?  it might just be a different FD ratio):

R 3.50
1 3.60
2 2.13
3 1.46
4 1.07
5 0.830

FD 4.11

all subject to further correction by those who know what they're talking
about, of course!
