This video should help you walk through the disable feature on your Vag-com. You need the actual version of vag-com for this to work. I use the VCDS. I find it works great
let me know if your VCDS isn’t able to do auto fix. I can copy the long code for you to put in manually.
I’m sure you can embed this some how, but I don’t know how

This should work on almost all new Audi’s. I know this will work on the S5 and the A5
