Adjust Kilometer Reading | Odometer Correction

Hello...

I have a car with 0 km on the odometer (brand new). Is there a way to change this value to 120,000 km using VAG-COM or another program?

"Regarding the alarm system, do I need to have it re-programmed, or does it work automatically?"

I would really appreciate a response.

Please do us all a favor and read the forum posts. The VAG-COM user manual from Ross-Tech also explains how to do this clearly. If you don't have a manual, you can download one from your distributor's website.
