Is this what your looking for Ex http://www.golfgtiforum.co.uk/index.php?topic=260248.345;wap2;wap2
Im on my phone so not sure it will link properly. But here's the coding:
STG09 (Central Electronics)> Access Authorisation: 31347 > Adaptation Channels> Channel (8 )-Leuchte27 NSL RC6-Lichtfunktion C27" > "Brake light on" set (default: nicht aktiv)
STG09 (Central Electronics)> Access Authorisation: 31347 > Adaptation Channels > Channel (10)-Leuchte27 NSL RC6-Dimming CD27" > on 100 Set(default: 0)
Auto coming home is also a good tweak.

P3ssa very helpfully posted this up in my "I blame you lot" thread.
I spent ages trying to get the car to accept the code for the full width rear brake lights today ably supervised by James75, we tried it in both his car and my own.
In both cars it would let us get so far then decide it wasn't possible and locked us out.
James has got several mods to work so it's not a cable problem (his Scanvinavian DRL's were activated easily enough whilst we were in the middle of being kicked out of the full brake light coding).
Anybody have any ideas on what I was doing wrong?
Exonian : Hi.
I apologise if you already know this, but each exterior light on a mk7 is controlled by a group of 19 x adaptation channels. In a paper that I wrote to explain how these channels work, I termed the group a
Leuchte channel set .
Without going into a deep explanation of the structure of these channel sets, they must be defined correctly in the first adaptation channel (i.e. the adaptation channel in parenthesis (1)) and the correct memory location must be allocated in the adaptation channels with parentheses (2) and (3).
From then-on, each remaining bank of 16 x channels is sub-grouped into 4 x 4 channels. Each 4 channels controls what the light actually does and the order in which these functions are programmed determines the priority of the function when there is a clash.
In a number of adaptation maps that I have seen, there are some Leuchte channel sets that are not active. In my own car for example, the channel set
Leuchte27 NSL RC6 (which does control the two inner tail lights and which you used in your tweak attempt) is not active.
Here's how the first three channels for this Leuchte-set looks on my car
(1)-Leuchte27NSL RC6-Lasttyp 27 = not active
(2)-Leuchte27NSL RC6-Lampendefektbitposition 27 = 0
(3)-Leuchte27NSL RC6-Fehlerort mittleres Byte DTC-DFCC 27 = 0
As a brief explanation of how these 3 channels work, the
lasttyp setting determines what type of light is installed whilst
Lampendefektbitposition and
Fehlerort mittleres Byte are memory locations for fault monitoring (I think)
If your car has the same settings, making the changes that you have described in your post will do nothing because the first three Leuchte channels have not been properly defined. It might be prudent to check how these adaptation channels are set in your car because it might explain what you have experienced.
So, the other way to program the two inner tail lights to act as a brake function is to modify the Leuchte channel sets:
Leuchte23SL HLC10 (left inner tail light)
Leuchte24SL HRA65 (right inner tail light)
However, because of the different ways that these channel sets can be factory programmed by VW, there is no universal set of instructions that will work for all models. It really depends on how VW programmed your particular model as to where in the 19 x adaptation channels to place the "Brake Light" and the "100" setting.
