One of the last nagging issues I have with this otherwise dam near perfect car is the hill assist. I can't turn it off, and I feel like its just in one of the German setting in another module.
Has anyone figured this out yet? Thanks!

stun4000 : is your Brake module (@ address hex03) a MK100 series unit, does it have a 30 x Byte long-code string and if so - What is the value of Byte 25? Don

Hey Don!
EV_Brake1UDSContiMK100ESP
Looks like a 46 byte code. 25th byte is 43.
I myself am not a coder but im looking to learn what I can. Any help thanks!

^^^^phil: Hi -So, Byte 25=hex43 means Binary = 0100 0011. Each of the digits in the Binary number is called a "Bit" and for the purposes of coding, you can think of each Bit as a separate software switch. The right-most digit is Bit 0 and the left-most is Bit 7. Your Brake module has Bits 0, 1 and 6 set high.
According to my information (which I've sourced from various places on the web), when Bit 0 & Bit 1 is set low (i.e. value=0), it means that Hill Hold is not active. Unfortunately, I didn't record the source of the information, but there is dialogue here that suggests that the tweak works. When you have made the change, Byte 25 = hex40 (or Binary 0100 0000)

DON!!! it worked! that's amazing. Hill assist is a bummer to begin with, but I live on a steep city block where I have to parallel park 50 times a week. The incline was my dear friend, and now we are reunited!
Is there any evidence of the new coding having other effects on the car? Its very vague and seems too good to be true, I feel like there must be some downside...what are your thoughts?

stun4000 : "too good to be true"? Why? There's no magic to this stuff and it ain't rocket science!!  I don't believe that there is any down-side to the change (other than no hill-hold) - but it's not a popular tweak. Anyway - if you observe any ill-effects, post on this forum and I'm sure someone will help Don
