The odometer reading (divided by 10) goes into Adaptation channel 09. Is if you wanted an odometer reading of 123456, you'd put in 12345 (and would then get 123450, or put in 12346 and end up with a reading of 123460. However, as you've noted, the question is: Do you need to enter miles or km, and of this, I'm not certain. Most often we tell people: Code the cluster so the odometer reading is showing km, then you should be safe putting in km, but whether that applies that to your particular cluster, I can't say for sure. Hopefully we'll hear from one of the techs who've actually done a New Beetle, but it is the weekend...
