@Barry Harkin : Thanks for posting the information.
To add to
@PetrolDave comment, I must preface my response with the admission that I'm not familiar with your Audi A8 - nevertheless, based purely on your CodingLog information, it's clear from a quick glance that except for address hex61,
none of the other records made actual changes to the modules.
In respect of the
Address 61: Battery Regul module - here's a more readable version of the record in your table:
hex61 module | From | From | To | To |
Byte | Hex | Binary | Hex | Binary |
0 | 30 | 00110000 | 30 | 00110000 |
1 | 30 | 00110000 | 30 | 00110000 |
2 | 30 | 00110000 | 30 | 00110000 |
3 | 39 | 00111001 | 39 | 00111001 |
4 | 31 | 00110001 | 31 | 00110001 |
5 | 35 | 00110101 | 35 | 00110101 |
6 | 31 | 00110001 | 31 | 00110001 |
7 | 30 | 00110000 | 30 | 00110000 |
8 | 35 | 00110101 | 35 | 00110101 |
9 | 41 | 01000001 | 41 | 01000001 |
10 | 4B | 01001011 | 4B | 01001011 |
11 | 56 | 01010110 | 56 | 01010110 |
12 | 41 | 01000001 | 41 | 01000001 |
13 | 30 | 00110000 | 30 | 00110000 |
14 | 33 | 00110011 | 33 | 00110011 |
15 | 33 | 00110011 | 33 | 00110011 |
16 | 31 | 00110001 | 31 | 00110001 |
17 | 30 | 00110000 | 30 | 00110000 |
18 | 31 | 00110001 | 31 | 00110001 |
19 | 33 | 00110011 | 33 | 00110011 |
20 | 44 | 01000100 | 44 | 01000100 |
21 | 31 | 00110001 | 31 | 00110001 |
22 | 4D | 01001101 | 4D | 01001101 |
23 | 38 | 00111000 | 37 | 00110111 |
So - bottom line (and to address your original question - which related to the changes that were made) - specifically from the data provided by the history file, it appears that the ONLY effective change that was successfully implemented from your records is
Byte 23, Bits 0-3 (i.e. the "lower nibble") on the
hex61 module.
Now, I don't have any information about this car that identifies the purpose of the 4 x software switches that were altered (perhaps someone else can help), but if the symptoms that you describe resulted from changes made to the car on 29/12/2020 -by force of the brutal logic from my analysis, maybe try reverting
Byte 23 to it's original setting?

PS: And, in respect of the hex07 question - if the search-vector "Interfacebox" is entered into the forum's search facilities, it's clear from the hits, that the Coding value
0000002 is not unusual for the hex07 module. Which of course doesn't mean that it's necessarily the correct value for this car - but it does suggest from a diagnostic perspective that this is perhaps a lower-order hypothesis to solving the riddle in this case (no offense intended to Dave)
