Hi,
i'm new to this forum, so sorry if this Project is not actual anymore.
Have you already tried activating in ?
I own a 1.2l TSI MK6 and i want to retrofit too.
So i have started - done an Autoscan - gone into coding - shows me to possibility to activate GRA but not .
I began thinking this one would not be possible, but i looked over a lot of Scans from other MK6. When i activate GRA the value of this byte was "20" other cars with had "40" coded. Manually changing it to "40" and apply did the trick for me.
After that i had 2 errors about missing messages from front-radar and another one i don't remember atm.
Please try it and post your Scan after that change. If that change isn't possible won't do it AFAIK.
cya
