Do you need to retrofit an Auto-Hold button to use this? My A3 e-tron has no button, just a blank space in front of the armrest:

2021 Jetta 6M. Byte 25, bit 0 and 1 checked, Hill Hold Assist 3 seconds. Bit 1 checked HHA 2 seconds. Bit 0 checked HHA 1 second. Neither checked, no Hill Hold. In the 1.4 that equates to 23, 22, 21 or 20. In the GLI it's 43, 42, 41, or 40.

GOOD NEWS EVERYONE! (although I'm sure this isn't exactly new information)

Thanks to the contribution of two comments left by Vasia on the google sheet, we now know that Bytes 1 and 3 are the 7th and 8th digits of the VIN respectively.

Yes, but you can not put Every Number there.
Only the ones by the ABS Supported "Car Type" or how it is called, which is saved in VIN 7&8 can be put there ....

Hi,

Ref T6 & Caddy 2K Sheet.
lt's BRILLIANT.

While checking my 2K vs another 2K with the upgrade I am doing I spotted a couple of possible minor things ...

Byte6 - OPTIONS (INVERSE IN BYTE 14)
Should read - OPTIONS (Mirrored in Byte 14 with lsb -> msb switch)


Also, from a sample of 2 Caddy Autoscans, so not exactly proof
Sheet info - Byte 15 - bit 7 Always 0
but in both the scans I have Byte 15=D3 so bit 7 is 1
May not matter ?

Thanks everybody,
Pete

We have some info but I'm not extremely confident building those from scratch. I'd post a link to the thread and complete scan in question here to see if anyone can assist.

I actually only need to change it from RHD to LHD.

OK, with any luck that may be limited to 3 Bytes but the Auto-Scan prior to modifications would be very helpful.

Byte 1 & 3 for RS3 and Caddy/T6 MK100-ABS coding is also the 7th & 8th digit of the VIN (like MK60EC1).
The coding uses the standard ASCII-Table for character sequence. You can see the table if you look inside the bin-files.
There are most of the ASCII characters available, but it seems to compare it with the Chassis Code(Vin7&8) and the allowed ones(2K,7H,...) are also stored in the bin-file, if I interpret it correctly.
The reason for the 7 character gap between "9" and "A" are the ASCII ": ; < = > ? @".


Code:
...
77=0  80=0
...
79=2  9B=K  2K  Caddy
7E=7  98=H  7H  T6
88=A  83=3  A3  Passat-NMS
...
A2=Z  AB=Z
...
------------------------------
...
94=0  66=0
...
9C=8  8D=V  8V  RS3(rdw)
AA=F  7D=F  FF  RS3(nar)
...
BF=Z  91=Z
...

Hi,

autohold enabling in Audi TT 2019: ABS Pump 8S0 907 379 K

Old coding : 32AAE08D2A9915AD41960066C2999706334C0754A8820043E960CC
New coding : 32AAE08D2A9915AD41960066C299970EB34C0754A8820043E970CD

No SA needed for coding. But 20103 needed for adaption.

Byte 15 (mirror Byte 25)
06 --> No autohold
0E--> Authold

Byte 16 (mirror with Byte 26)
33 --> No autohold
B3 --> Autohold
