I know this isn't exactly T6 related, so apologies in advance...but this is the forum I'm most active on nowadays so thought best to post here...
It's well documented elsewhere on how to enable indirect TPMS, 03-ABS Brakes, coding, then activate byte 12 (for T5.1) or byte 15 (for T6) bit 4. It may also need activating in the instruments coding if it's not already done. VCDS/VCP/Carista can all probably do this.
The issue on T5.1s is, there is no way of resetting it short of using a diagnostic tool as mentioned above on channel 042 on ABS Brakes to do a reset, or wiring a special button in to the ABS module. This doesn't seem to be an issue on any T6s as it always comes up with the menu in the instrument cluster. However I recently did a little job on a late model T5.1 for someone that had got a reset menu enabled in the instrument cluster, all from the factory. I had heard this mentioned in posts in various places, but nobody could confirm for definite that it was real on a T5.1, or what was different to earlier models. Obviously as part of my work I made sure I needed to do a full scan to see what's going on
I can confirm this reset menu will only work on a T5.1 if you have ABS module 7E0907379L (both HW and SW). Unfortunately mine is 7E0907379K (SW) and 7E0907379E (HW), I attempted to update it to the L revision but it was not possible.
