Hello everyone, I am the owner of a Leon 2021 with software version 1940. On Instagram I discovered this page which managed to put the purple LED on the dashboard with Obd. I wrote to him and it is possible to do it but he would need a car, I come from Italy, let's see if I can get him to tell me how and if so I will let you know. View attachment 39846
hi, I contacted the page but unfortunately it doesn't want to tell me how it did it.. have you been luckier?

To answer nikolas7203, unit 09 is the central eletric unit in obd eleven in which we can modify, to an extent, the coding for ambient light.
Also, for attaczz, you still didn't share what you've done, it would be nice

To continue our search for the purple color,

I need your help:

My problem is to access more colors for the interior led lighting of my Leon 4 (the changes of the leon 3 do not apply to the 4, the menus, submenus, long coding and adaptations are different)

It would seem that these 4 lines of code (this is the factory coding, 10 choices, 10 different colors) in unit 09, under "interior light hmi config"' determine how many choices are possible (2, 10 , 12, 17 , 20 etc..) and what colors are available (redundant or new):

interior_light_hmi_config
Hmi ambient colors bitmask
3FF
Hmi contour colors bitmask
3FF
Hmi ambient colors fod bitmask
3FF
Hmi outline colors fod bitmask
3FF

The problem is that it is a hexadecimal code and it determines both the number of color choices and the different colors that can be accessed.
For example:

8b00ff gives 12 color choices and all are different.
7fffffff gives 20 color choices but these are 2x the same 10.

Not having the technical level, I cannot understand the correlation between a hexadecimal code and its consequences on 2 aspects: number of choices and number of different colors.

Does someone have an idea ?
I do wonder if it's being held off by another setting somewhere in OBDeleven, or even if it's like trying to retrofit something where you can't activate something that the car cannot detect. One example is Travel Assist, you can't activate the capacitive steering wheel in OBSeleven without one actively being connected to the car, it seems.

I hope it isn't something like that, but just brainstorming a new idea I haven't seen mentioned anywhere.
