Ok, I am going to read it now, BUT are you sure you did as I listed, you have 34 modules in which 20 still have faults, and going by you post times it would seem that you scanned and tried to clear 20 plus modules individually in 13 minutes.....

TERMINAL 15
Still looking, but quick question, did you put that tiny red wire back on the positive terminal of battery ?
You have many that show terminal "15" short to +, or to -, and even "open", I am searching for where terminal 15 is located.
OK,
If you look at all the items that are on terminal 15 in the PDF Audi A8 fuse layout attached below, you can see that almost all of you faults are tied to terminal 15, terminal 15 is a relay (J329) located below the instrument cluster behind knee panel, J329 is located in slot #3 of drawing A97-1226 in the same fuse layout PDF, just a note terminal 30 is live all the time, BUT terminal 15 is switched, terminal 15 also comes out of J518 access/start module (KESSY) located under drivers side carpet, The J518 allows the continued use of terminal 15, see links for information, I would start with the relay, it may be numbered "460" or "370", but try to verify that the circuit has power to supply terminal 15 first.
I am going to bed, it is 2:57 AM
Zzzzzzz

I went in order and cleared the codes from the individual modules, moved to the next one, some wouldn't clear, and did a full auto scan after complete. Should I have done an autoscan between modules?

That relay is in the same block as the air compressor relay?
I should note that my mechanical apptitudes are much higher than my electrical ones. I can easily pull the trim panels and access this area, but am fuzzy on how to make sure 15 has power. Do I need to have the key in start position since its switched? And just bridge the standard terminals with a meter? (Where 37 & 80 would be)
And yes, the little red wire is still attached to the neg terminal on the battery post.
The previous owner used a huge battery, I don't think it is OEM size, however.

Response in red.

Yes, right below the orange 40 AMP compressor fuse.
This video will help as far as removing the needed dash pieces for access to relay, it is a guy doing his air suspension, but shows what you need to do.

Just with the key in the on position, I think, but try it either way, or just get the relay and try it out, Also maybe pull the cover of said relay to inspect for proper operation.
I will look at would pins to test and will be right back.
Do NOT "bridge" the terminals, put the black wire of your tester to the body of the vehicle for good ground, and then with the red wire of tester probe both of the big blade sockets for power, then just to be sure that the circuit that engages the relay is also in working order, take both the red and black leads of your tester and insert each probe into the small blade sockets while turning the key on and off to test for power.

IS THIS A TYPO ???
The little red wire belongs on the POSITIVE cable/post of the battery.
The OEM battery is very large, post model number of the battery you have installed, bigger is better......

Little red wire is on the red terminal, Yeah- I'm that much of an electrical idiot that I don't know which side is pos or neg, I generally just go by red or black.
