Explanation: I am trying to know if any type of BCM coding for DCLs would not even be necessary. (to differentiate the DCLs from the SCLs)
I guess you're inside a garage and you're looking on the wall if the light patterns projected by the headlights move when you turn the steering wheel.

Output tests with VCDS suggest that steering wheel angles (data) do not reach the 55 unit in normal conditions.
Do the G85 Basic setting (03 Address) again.
Hello Fernando, you have absolutely right about the procedure that I follow !

I did G85 basic setting the result above

Then I put the new coding in bcm and the result was to have 2 false as previous

According to the video (Roomster)...

... the DCLs and SCLs move/ON from a steering angle of very few degrees, I would even say that from 0->1 degrees of steering angle.

If someone remembers this discovery ... viewtopic.php?f=56&t=58703&p=517482#p517482

BCM adaptation (PQ25):
Channel 33 Angle required to activate the static cornering lights. Factory setting = 80º
Channel 34 Angle required to deactivate the static cornering lights. Factory setting = 30º

What would happen if you set the value of these two channels to 0 or 1?
Then I made exactly what you told me in channels 33-34 the results from the beginning to the end .

I want to add something in our conversation , the function of corner light (fog lights) it is impossible in my case, because in position of fog lights , I have day lights .

If it had been possible the SCLs from the beginning surely you would not be doing this retrofitting (DCLs). :)

We are trying to understand the operation of the AFS unit for DCLs in the Skoda PQ25 and how the other units are involved. There is no kind of info about it in any Skoda forum, or rather in any forum.
The video provides a series of clues. The SCLs in the 6R have steering wheel angles determined from the factory for their operation, as you have seen, however for Skoda Roomster/Fabia its operation is practically since the steering wheel starts to turn.
I thought that these angles (data) is the correct information for the operation of both the SCLs and the DCLs in the Sk Roomster. Just that.

I guess it is not necessary to tell you that if you do a test and it does not work you must return to the original state.
Never leave the tested values ​​or bytes/bits that did not work.
Therefore, return to BCM coding without faults and re-enters the previous values ​​of the adaptation channels, ... according to your tests, we already know that they have had no effect in the AFS unit.

If the VCDS output tests run your DCLs correctly, they should work in normal conditions ...

Hello my friend Fernando, i returned to the original state bytes/bits , channels 33-34 everything as it was .
No error and afs module works with no problem only when I am doing with vag com out put tests .
When I am starting the engine with lights open they made auto correction on starting position .
Tell me what else can you imagine to do ?

Talking just as an observer

What do byte's 21 bits translate two in VCDS? (I don't have access to my Skoda or VCDS to check it myself).
I compare the two autoscans from two cars that have DCLs (Vasilis' post #214)

And I can see that both cars have the same value

exantas, Byte 21, you will have to translate from Spanish to Greek or English.

;LC,21,0,Combinación de las luces de circulación diurna (0 = 20 W, 1 = LED) instalado.
;LC,21,1,Sin regulador de intensidad de las luces interiores (valor fijo).
;LC,21,2,Activación de la luz estática de giro mediante la palanca de los intermitentes.
;LC,21,3,Activación de las luces estáticas de giro al poner la marcha atrás.
;LC,21,4,Intermitentes de techo instalados (supongo que para aumentar el consumo y evitar error de diagnóstico).
;LC,21,5,Desactivar las luces de niebla delanteras al poner las luces de carretera
;LC,21,6,Luces de estacionamiento en ambos lados. Instaladas.?
;LC,21,7,Luces antinieblas delanteras con función de luz estática de giro (via BCM) instaladas.



Vasilis, the problem is that the steering wheel angle data does not reach the AFS unit. The AFS unit works properly.
Coding ? Adaptation ? Parameterization ? I don't know ... it would be necessary to find a Fabia or Roomster with DCLs and make these readings of the units involved.

Thank you Fernando. For the record

;LC,21,0,Combination of daytime running lights (0 = 20 W, 1 = LED) installed.
;LC,21,1,Without dimmer of the interior lights (fixed value).
;LC,21,2,Activation of the static turning light by means of the turn signal lever.
;LC,21,3,Activation of static turning lights when reversing.
;LC,21,4,Ceiling flashers installed (I suppose to increase consumption and avoid diagnostic error).
;LC,21,5,Turn off the front fog lights when setting the road lights
;LC,21,6,Parking lights on both sides. Installed.?
;LC,21,7,Front fog lights with static turn function (via BCM) installed.

(is what I would have done before changing the BCM)

The warning/error light in the IC is because the cornering lights installation in the BCM was activated. Byte12 Bit6.

Another observation. On vasilis coding byte 12 is
3E = 0011 1110

Both cars with the ACL have
Car 1: 7E = 0111 1110
Car 2: 7C = 0111 1100

No matter how that Bit is setted, I think the Byte12 Bit1 is for some MY Jetta-Instrument Clusters (PQ25) of that part of the world that is not the rest of the world... :lol:

Sometimes I think, sometimes only...
I remember the bixenon headlights of one of my ex-Audi A3 (2.0 TDI BKD 140HP, ...the king of the road :lol:), among other functions, they had dynamic cornering lights, which turned on/were available when a certain speed was exceeded.

It may be that the Roomster video is cheating us slightly ... and as the diagnosis with VCDS tells us that everything is correct for your DCLs, it could be that they work from a certain speed.

Test your DCLs at various speeds. Remember that driving safety is the first thing to consider for you and other drivers.
They should be available from low speeds.

If the test is successful, it would be very interesting to know the speed at which your DCLs are available/work.

Good luck!
