EDIT 01/12/2023 - ID7 has been updated and I believe this method is outdated. I will update as soon as my IDrive has updated and I can test this again.
I thought I would post my method for coding ambient lighting since a lot of these instructions are spread out over the bimmercode thread. Here it is, all of it in once place, my step by step instructions. Please, if you find any discrepancies, let me know and I will update it.
You can use expert mode in bimmercode to code any hexadecimal color, almost 16777216 different colors.
What is described in this thread is changing the colors that will display in the three sectors of the interior when you select a color in the iDrive menu. These three sectors are:
1. DOOR and DASH
2. FOOTWELL
3. MAP LIGHT
I've done it to my G82, but it's the same process in pretty much all the G-series BMWs.
Disclaimer: Do this at your own risk. While changing colors will not likely brick your car, if you poke around enough and don't follow these directions, you might change something inadvertently with unforeseen consequences.
I HIGHLY recommend getting a ENET cable for any EXPERT coding simply because it's FASTER and more stable.
Trust me, the cable is 10 times faster than any OBDII wifi or bluetooth dongle. I got mine
here and it works perfectly. You just need a ethernet to lightning adapter for the iPhone or whatever smartphone you are using.
Here's how to do it.
In bimmercode:
Go into expert mode
Select
BDC_BODY3 ECU
Select
360A/LIC_LCI_COLOR_LIBRARY_DATA
Select
360D/LIC_LCI_COLOR_PROFILES_DATA
Then choose
G20G21G26G28G80_Lichpacket_code1 - this is your car, the G20, G21, G26, G28, and G80 generations)
Then you need to find the 9 bites by number that represent the menu item you want to choose. Here are the BRONZE bites:
Bronze bytes:
18,19,20 - (These three represent the color in the DOORS and DASH)
23,24,25 - (These three represent the color in the FOOTWELL)
28,29,30 - (These three represent the color in the MAP LIGHT)
For instance, let's say you want your ambient lighting to be RED instead of BRONZE when you select BRONZE in the menu. Replace these bites with the hexadecimal color code for RED. You can look up the codes
here.
The hexadecimal code for RED is
#FF 00 00
IMPORTANT: there is a bug that the system does not code any
FF correctly. Instead use,
FE, which is only one value off true full RGB red. It's close enough and you can't tell with the naked eye. So, for any hexadecimal color that uses
FF, always replace it with
FE! If you use FF at all, the MAP LIGHT will not work. Nothing serious, and the fix easy–just recode, but save yourself the headache and never use FF.
So the RED code we will use instead of FF 00 00 is
FE 00 00
You need to change the 1st set of bites - 18, 19, and 20 to make the DOORS AND DASH red like this:
Go to the 18 bite and replace it with
FE
Then the 19 bite and replace it with
00
Then the 20 bite and replace it with
00
Do the same with the 2nd set - 23,24,25 to replace the FOOTWELL light
Then the 3rd set - 28,29,30 to replace the MAP LIGHT
You can use different hexadecimal color codes to put whatever color you want in each set. So you can have a different color for the DOOR AND DASH, the FOOTWELL, and the MAP LIGHT.
You can do this to
all the menu color options:
Lilac bytes:
78,79, 80
83,84,85
88,89,90
Blue bytes:
48,49,50
53,54,55
58,59,60
White bytes
3,4,5,
8,9,10,
13,14,15
Orange
33, 34, 35
38, 39, 40
43, 44, 45
Green bytes
63, 64, 65
68, 69, 70
73, 74, 75
IMPORTANT: You have to code all of your menu items at once. If you go back to change or add anything, all the other menu color options go back to default.
So, once you change all your bites and you are ready to code:
Hit
BACK
Hit
BACK again and the CODE option should appear.
Hit
CODE
I've coded my BRONZE to be pure RED, which is nice against my Fiona Red interior. I've also changed my BLUE to a CYAN color, and my LILAC to a CYAN and PURPLE combination.
