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:

Yes, button retrofit and wiring plugued on the ABS pump needed + Coding

I wish you would have the same solution for a T6 MK100 unit.

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.

 

[dnoermann]

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

Does anyone got same info for 47 byte abs modules?

Does anyone got same info for 47 byte abs modules?

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.

 

[Dana]

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

Sure, il get it tomorrow. Thanks

@Somnus
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 ": ; < = > ? @".

...
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

We have two Audi TT 8S Race Cars - https://www.darksidedevelopments.co.uk/audi-tt-cup-8s-2-0-tfsi-dsg/

I need to try and recode the ABS to help with the bigger brakes. It really does not allow you to trail brake at the moment. The factory servo is removed and a Tilton Pedal Box installed.

I checked the coding against the Google Sheet, and it seems everything is completely different

Address 03: ABS Brakes Labels: 5Q0-907-379-IPB-V1.clb
Control Module Part Number: 8S0 907 379 F HW: 8S0 907 379 F
Component and/or Version: ESC H42 0530
Software Coding: 32AA208D1A9915B1419A0068C2959706334C0458A8820043E960CC
Work Shop Code: WSC 34262 001 1048576
ASAM Dataset: EV_Brake1UDSContiMK100IPB 060017 (AU37)
ROD: EV_Brake1UDSContiMK100IPB_060.rod
VCID: 44D14A6AAE1086DB83B-8010

Byte4 and Byte17 are not mirrors

Neither are Byte14 and Byte22

The pump is a 8S0 907 379 F / 8S0907379F - https://www.ebay.co.uk/itm/223837020662

Any ideas?

Thanks

I would urge you to log your deceleration rates to determine if you are running to the problem that we have been struggling with for years on this platform. I've been trying to resolve this issue myself on multiple TTRS and RS3 track cars. Several competitive racers I know were forced to sell their vehicles due to this limitation as it was not permitting them to be competitive in their classes.

The ABS system on these cars is limited to roughly 1.1 G in braking (as logged, not as displayed in the dash), we have been able to address this on the golf platform by adjusting brake bias and adding more rear brake pressure but these settings are not available on the TTRS/RS3.

I started a thread here to try and get the issue resolved:

Adjust brake bias or abs pump coding

I have a 2018 TTRS (8S) that I actively track and am looking for a what to change the brake bias to allow for more rear brake pressure. On other VW/Audi cars I could adjust the "Brake Boost" and "Hydraulic Brake Booster" values which allows for more rear bias. Unfortunately on the 8S TTRS these...

Byte4 and Byte17 are not mirrors

No, it is:

Byte 02 <> Byte 18
Byte 04 <> Byte 19

Byte 14 <> Byte 24
Byte 15 <> Byte 25
Byte 16 <> Byte 26

We run Racelogic VBOXs in 2 identical cars. The only difference is one does not have the factory ABS. Please see below

Red is Factory ABS, Blue is without. Both are maxing out ~-1.1 (this is the same track, fastest lap of 2 different drivers)

I've got a Golf Mk5 without the factory ABS and that will still only do ~-1.1. We run Yokohama A052 Tyres (amazing road legal race tyres)

What else did you do before throwing the towel in?

No, it is:
Byte 00 <> Byte 17
Byte 02 <> Byte 18
Byte 04 <> Byte 19
....
Byte 14 <> Byte 24
Byte 15 <> Byte 25
Byte 16 <> Byte 26

Thanks for that, how did you figure that, just calculated it?

How do I figure out which Bytes correspond to the brake sizes so I can try to play with those?

Appreciate the help, I can post whatever is required to assist increasing the knowledge on these pumps

Cheers
