If anyone finds thos topic still actual, I had the same problem. Thing is, you need to match sw version (or higher) of clockspring.
As I tried to replace my spring on kodiaq
Which had the sw code 235. I tryed genuine valeo spring with sw code 195 and it didin’t worked. I had coding problem same as mentioned at this thread before where first coding number which was responsible for cruise control fuctions gave me an headache. Lucky me, at workshop we found one spare from 2021 octavia, which had same sw235 code and it took 6414 code I needed. Older sw versions just doesn’t support coding of cruise control by separate handle behind the wheel. They support vags who have autopilot controls on steering wheel. As on newer sw versions, vag included both steering wheel and separate handle autopilot coding.
