Just to make sure, the types of pins for the BCM connector (the one with the 73 pins) are
000979009 for the small "holes"
000979151 for the medium "holes"
000979242 for the big "holes"

Come to think about it, the one that your arrow is pointing to is likely an MCP 1.5, to the left of that is an MCP 2.8 and the far right corner is an MCP 6.3

I have started the installation
First step the wiring.
I found some pins on the BCM that are associated with the "leuchte" description on the adaptmap and have no wires attached. I decided to wire 3 so I can try other ideas in the future
The BCM T73c
Removing the BCM and find the connectors
Opening the connector T73c
Wiring 3 cables to pins 35, 36, 37
Next step is adaptation.
I bought a one-year VAG PRO subscription to OBDeleven to be able to unlock the SFD of locked modules (such as the BCM) and now I'm looking a little at how to program the "leuchte" lines.
I'm a bit familiar with the "Leuchte" board adaptation method, but I still have a lot to learn.
For example those are the lines for the pin C35
I don't know how to deal with those 2 lines
ENG263449-ENG116482-Leuchte 32 AMBL 2 C35-Fehlerort mittleres Byte DTC-DFCC 32,00 ,20

I think you can ignore the error detection for now, if you install the correct type of load. Are you familiar with the writings of DV52 about the light channels?
Re: Skoda Octavia MK4 2023, 2.0TDi DSG Ambition
Posted: Fri Dec 15, 2023 9:46 am
Yes, I read DV52's writings about light channels. Excellent work and understandable.
The only thing that is not clear to me is the error detection lines. If I can leave them at 0 for now, that's fine. I don't want to mess with something I don't know.
But I don't know if it will work without fixing these lines. if you know that then it's fine.

well, first attempt for adaptation the "leuchte" lines
I unlocked the SFD with the ODBeleven and i did the adaptation with VCDS.
I tried several combinations but no one worked so far.
I tried with VCDS, then with ODBeleven. The adaptations changed but there is no change at the end of the wire C35.
Any ideas ?

set to different function like terminal 15, terminal 58 to try that first
Re: Skoda Octavia MK4 2023, 2.0TDi DSG Ambition

I went to my car again to try what you suggested iichel.
Without doing anything I checked to see if the cable from pin C35 was getting power and.... yes it was. It worked simultaneously with the position lights, exactly as it was in the adaptation. Immediately there was an error to the dash, something like error to light system, i don't remember exactly.
So made some other adaptations, changed to
C35
C36
C37
to check the response of each one. Nothing happened.
I finished the SFD unlock and made a fault scan.
An error appeared
So i wondering about the correct way of changing the adaptation with the SFD lock. It may take some time for the new settings to work or something similar.

Two hours after the second attempt, the C35 working fine (i changed the "Lasttyp 32" from to "allgemaine_LED_met_Open_Load_Diagnose12W" to "LED_Kleinleistung_ohne_Open_Load_diagnose".
The error gone. But the C36 and C37 not corresponding to any change.
Possibly not working even though the Pins are present in the BCM.
I searched and found that in Golf8, pin C35 and C61 are responsible for the front LED bar on the mask. The BCM is the same in GOLF8 and OCTAVIA. Pins C36 and C37 are not used there either.

is there a physical pin present in the BCM?
