For that exercise you will need to flash it to standard, Vw have asked dealers not to do it now as they have corrupted a couple whilst doing so. They will do it with bended arm and a disclaimer. Other software makes it hard to read and redo when other tune is on there. When stock i would be having a chat to Gavin(h100VW) , Custom code can cater for the out of the box tunes.
Good luck with it
