The instructions, tips and procedures come from trying myself, trail-and-error, from car forums in all countries and languages, from Ross-tech and VCDS distributors.


I don’t accept any responsibility for things going wrong when changing codes to your car or using procedures written here.
Usage of this information is at your own risk.



Take precautions

  • Make sure your laptop operating Vagcom / VCDS has a full battery or is powered enough. (when the laptop is powered down during a procedure you could damage the cars hard- or software for good.

  • Before changing codes, write down the original value.

  • Always start with an AUTOSCAN. In the newer versions of Vagcom / VCDS (version 9 or higher) all long codes are saved to a file on your laptop.
