Traction Control - ESC/ASR & HDA switch retrofit

ABS
byte 18 bit 0 ==> "1"byte 18 bit 1 ==> "1"

Thanks for your help!

Ok so I’ve set these, and also reset that Gateway setting back to the original value.

No errors this time, so I’m going to wire into the ABS connector next.

Signal wire to the ABS module is now in pin 9, with the little sealing plug installed. No lights on the dash so far, so my van still has working brakes!

Next I touched the other end of the wire on ignition live (still need to get the actual switch) and SUCCESS!

Many thanks indeed to @mmi for the code discovery, and also @Bundy88 for sharing data. T6.1 hill descent appears to be cracked!

Also huge thanks goes to @Pauly for providing behind the scenes quite a few build sheets with full VCDS data packages. Wouldn't have been possible without all the data as every T6.1 ABS coding is unique
And of course @drinfinity thanks for experimenting.
