    [coding] ACC and overtaking on the right prevention (A6 C7.5)

    Guest-only advertisement. Register or Log In now!
    For all ACC users around here - do you know what is the coding for the ACC module that allows overtaking on the right? Without this ACC in my RS6 is basically useless (unless I feel feisty and I want to stick to left lane only). I got a car from EU market which has this dumb feature turned on -> It's pointless on a highway with more than 3 lanes, so I am looking for options to disable this entirely (or cripple ACC so it works like a normal cruise control).

    I know it's possible to disable this on VW platform (here or here), so I was hoping that Audi coders already figured it out, but when checking latest library files on VCDS I was unable to find adaptation/coding settings that would allow me to have ACC working without overtaking prevention...

    Any help/hints? Or is there anyone with non EU spec car which does allow right lane overtaking, who could share the coding setup for ACC module?

    The car is 2018 RS6.

    (this post is for the right-hand traffic)

    I'll reply to myself:
    13-Auto Dost. Reg -> Coding -> Bit 1 -> set region to 01: North American Region (NAR) OR China (CHN)

    It does not break anymore when approaching slower cars on left lanes (effectively allowing me to overtake using right lanes).

    I just want to add to this, this IS the answer even for left hand drive cars. I am in Australia and this works.

    I was searching for this and for some reason thought setting USA or China, or Canada which is option 1. Would not work or screw up things for the fact that our fast lane is on the right, But it does indeed allow passing on the left now, and passing on the right in the fast line is unaffected.

    Just wanted to add this for future people who may search for this. I would assume this will work in any Audi that does not clearly have the Overtaking prevention as an option like the RS3 does...
