@jonnieb2018 - Here's my Central Electrics map attached:

I can guess what's happening (something which you might miss):
By changing the 2 channels as per the forum, you are indeed activating the function, but the intensity may still be set to 0, so you will not see any difference.

The below 2 activate the function (for each side):
- Leuchte26NSL LA72-Lichtfunktion C 26 change the value to Blinken links Hellphase (left rear fog light)
- Leuchte27NSL RC6-Lichtfunktion C 27 change the value to Blinken rechts Hellphase (right rear fog light)

While the following 2 control the intensity of the fog light when you signal / hazzard (I have mine set to 40%, as more would again overshine the standard blinkers):
- Leuchte26NSL LA72-Dimmwert CD 26 set this to your prefered percentage (left rear fog light)
- Leuchte27NSL RC6-Dimmwert CD 27 set this to your prefered percentage (right rear fog light)

Good luck!

Ahh I understand now - that is why!

Will give it a go later tonight W4 -great stuff thanks mate for sharing info :p

p.s. Will the fog light still function as normal or not?

One more question if anyone knows -how do you change the front indicator lights from the standard on/off blinking to a sweeping effect - this is what it looks like in photo? (I do have Matrix headlights):-

-Fog lights will still work as normal (even intensities are separate, so fog is still 100% when you press fog, while it goes to whatever you set it to when you signal).
-PM me your number
-Are you sure you have Matrix headlights? I thought the same, but it turns out I only have Full LED headlights (they look the same when turned off), so only blinking is available....if they were Matrix they would swipe by themselves.
P.S - My car is in my signature actually

I tried these adjustments on my 2017 UK TTs but it doesn't appear to have made any changes:

Rear stop blinking (together or opposite) with the turn indicator
Rear turn indicator blinking (together or opposite) with the rear fog light

Has anyone completed this successfully in the UK?

J :)
I have managed to get the left to blink with the indicator in unison but I cannot get the right to work the same. PLEASE WRITE DOWN EVERY CHANGE YOU MADE AND WHERE! I had the left indicator working but the right night light blinked in opposite. So be very careful or there is a world of pain awaiting you. I sorted out the problem eventualy but took me 2 hours of OH SHIT! Every 30 seconds!
 
Ok That did the trick M4, much better look and will be safer too, adjusting the light intensity levels worked! :), leaving them at 0 - the lights wont work so I set to 65% -all good!

I have done so many mods and tweaks over the years in the A5 mainly -got to know the electronics inside out but not the tt in this much depth.

The below 2 activate the function (for each side):
- Leuchte26NSL LA72-Lichtfunktion C 26 change the value to Blinken links Hellphase (left rear fog light)
- Leuchte27NSL RC6-Lichtfunktion C 27 change the value to Blinken rechts Hellphase (right rear fog light)

While the following 2 control the intensity of the fog light when you signal / hazzard (I have mine set to 40%, as more would again overshine the standard blinkers):
- Leuchte26NSL LA72-Dimmwert CD 26 set this to your prefered percentage (left rear fog light) I set to 65
- Leuchte27NSL RC6-Dimmwert CD 27 set this to your prefered percentage (right rear fog light) I set to 65

How do I attach a video? wont let me -what format?

Front headlights are not matrix, just read up on this so cant change them -not to worry!

I tried to have the 3rd brake light ON doing the variation posted under and suggested on this thread, but unlike reported, the brake light didn't go off 20 seconds after the car has been locked (I waited around 3 minutes..)
can somebody post the proper coding to have the 3rd brake light ON when low/high beam are ON with the knob in the AUTO position (and OFF when low/hi beam are off too, and obviously when the car is locked)?
thanks
8 Leuchte22BR MA57 Lichtfunktion C 22 change the value from not active to:
-active 100%, the light will be always on, in any position of the light switch, even if you turn off drl from the menu and it'll remains on about 20 second after locked the car. it's always on and stop!

thanks again!
any idea about how to have 3rd light ON only if low or hi beam is ON?
So what I understand is the first line below (C22) makes the 3rd light active (on), the next line (D22) is what you tell it you want to do eg use them as DRL -so the option must be in here in the menu list? :p

Leuchte22...C22 change from not active to standlicht allgemein
Leuchte22...D22 change to daytime running lights
Leuchte22...CD22 change to the value from 0 to your choice (100 is the max intensity of the third light, my advice is 10)
 
tried to activate Leuchte22...D22 change to daytime running lights, problem was -as I reported before- that the 3rd light remained ON even after having locked the car and waited for 3 minutes... I suppose that car battery would not be so happy... :lol:
 
Her is a short version of how to undo your rear indicator additional functions that you programmed wrong if all else fails. Go into each address and switch off, Niect active on A, B and C FUNCTIONS...IE.. in 20BR LA71YOU WILL FIND A21, B21 and C21, select these off by selecting Niecht active. After you have done this to all addresses you changed that caused the first issues then test indicators, they should work as normal. If again you wish to input new functions then change C21 for example, try indicators and you should see no difference, then activate A21 save. Update function should now work. Do the same for other side. Hope this helps.

strange, so maybe its the setting for C22, i suggest look for another function, not 100% or activ as it sounds like this turns it on permanently?

thanks to both, I will begin testing teh 3rd brake light first...
I disable the coming home low beam so I just have the DRL on at a high intensity -looks great.

I tried the rear indicators set to the reverse light as well - it looked too busy and would confuse drivers so reverted back to what I have and to stay within the law.

So here is the list of possible functions for the 3rd light:

-Enable auto handbrake when shift in P (my cable can't have access at this unit, so not tested)
Unit 53
Security access, code 78713
Adaption
Find "shift p to epb"
Activate it and done.

I dont think Module 53 is in my car or at least I cant access it. Is it only availanle with hillbold?
This would be a really useful feature I think.

Has anyone else done done this one?

J :p
