JR: arrhh......... that's better - thanks for shifting your questions to the forum proper!!
OK- interesting project!
First point, I can't access your admap - when I try your link, it tells me that it's converting something! I just need the raw .CSV file from VCDS - nothing fancy!
Second point - I'm more familiar with Golf mk7/mk7.5, but your Superb shares the same MQB platform build - so much of the DNA in both models is similar
So - let's talk about BCMs! Since this car is MY17, I assume that the hex09 module doesn't have an active long-code (VCDS often reports this as a long-code value with a zero-string). If so, the critical aspect of the module's coding for your purpose (I think) is the channel below:
- ENG141650-ENG141973-Fernlicht_assistent-Erweiterte_Fernlichtsteuerung
This channel tells the BCM whether the car has HID, or incandescent headlamps and therefore how to manage the high-beam function and other stuff like AFS etc.
In this case - I suspect the setting for the channel above is something like "AFS: FLA: BCM-Fernlicht", or similar - which means that the SHUTTER Leuchte-sets are activated on this car. And importantly, it also means that the normal High-beam Leuchte-sets for incandescent headlights are NOT activated. That's why your intended Leuchte8FL LB39 is factory disabled on your BCM - it's because this would have controlled the left-side high-beam lamp had this car been factory built with Halogen headlight fittings!!
As an overall response to the matters in your post - I reckon that your general approach should work. That said, care should be exercised in choosing the Leuchte-set that will be used to power the LED strip because not ALL deactivated Leuchte-sets have their appropriate pins populated on the housing socket. In fact most factory deactivated Leuchte-sets are missing both the physical pin on the BCM motherboard and the associated electronic components. However I suspect that this is not the case for B39 and B2. If you intend to use any other Leuchte-set - I suggest that you physically sight the appropriate motherboard pin before proceeding with the project.
As for your proposed programming of Leuchte8FL LB39 - a few observations for your consideration:
- As you will doubtless be aware, the factory DRLs have a facility called "DRL wink" - which switches-OFF/dims the DRL on one car-side when the turn-signal is activated during day-light conditions. I assume that there is only ONE LED-strip in this project. I note that your proposed programming of Leuchte8 includes DRL wink - but it only uses the left-side Leuchte-command. If you want DRL wink to work properly on the LED - strip, you will need to also add the right-side Leuchte-command - which is Blinken rechts aktiv (beide Phasen). Also, you need to change the Dimming Direction channel value for DRL wink to minimize.
- Fehlerort mittleres Byte DTC-DFCC and Lampendefektbitposition channels are used by the Leuchte-set for diagnostics. These channels point-to memory locations (I think)- which means that it's important that the values only appear ONCE on the 35 total Leuchte-sets in any single BCM. I'm not sure what settings to apply in this case - but it might be easier to simply not use the diagnostic function at all. If you agree with this approach -I suggest that you set the value for both channels to zero
- I note that you have also included just the left-side part of the Single-Side-Parking-Light function in your proposal. Why - where will the new LED strip be positioned on this car? If you want to keep SSPL in the design - is it appropriate to also add the right-side Leuchte command (which is Parklicht rechts)?
Finally - from my past experience with these type of "more-innovative" projects, I have found that it often helps to "bread-board" as much of the design in the first instance before actually installing the various components in a permanent manner. Of course it's entirely your decision - but I suggest that you consider a temporary set-up as an initial proof-of-concept before you purchase and fit the LED strip.
If this was my project - I would first experiment with the new Leuchte-set values using a test LED connected to pin B39 (as a temporary set-up). You only need a single LED connected in series with a 390ohm resistor for this purpose which can be purchased at your local hobby shop. When you have correctly driven the test load with no BCM errors - buy the LED strip and the remaining project paraphernalia.

PS: As for your final question - given that you will only need ONE BCM socket pin - I suggest that you buy from a dealer. Yes, it will be over-priced - but it shouldn't be a large component of cost in the overall project budget!!

Please don't PM to ask questions about coding, or vehicle repairs. The better place to deal with these matters is on-line, in the forum proper. That way you get the benefit of the expertise of the wider forum! Thank you.

parameter file, which was sourced from a Skoda Superb overseas that had SLA headlights fitted from factory.
