Lighting Channels - Seat Leon KL

Hello, I noticed a lot of people were struggling with getting the lighting channels for the Seat Leon KL to code lights to do special features, etc.

I played around with my car today and I have figured out what most of the channels do, not as such which specific light they control, but what it actually does, although finding out which one would be pretty easy as you can just do an output test on it and see what does what (I can't do this at the moment)

Please find below attached a google sheets page & a directly pasted paragraph of the lighting channels I have currently figured out, this may be different on different models, I'm not sure, and I'm also not responsible for any problems or issues caused by you changing these light codings.

(I will be updating the google sheets page with new findings, I will not be updating this thread with findings as I won't remember to haha)

I would imagine that things like "HR C27" etc shows the location of the light, but I'm not sure how to find out what these codes mean.
