Quick update:
It’s possible to code the ambient lighting setting to the instrument cluster. This allows you to select the brightness of the ambient lighting manually instead of doing it by holding the roof button. The option is in instrument cluster. And it appears in the interior lighting menu.
Also the wing mirror puddle lights. You can set these to “on” even when folded. This is in the front drivers and passenger door module. You must code both sides for this to work. The puddle lights stay on even when the mirrors are folded.
Still trying to activate the exhaust button. Found a option in rear electronics but I believe there are other modules to code aswell before it will allow activation in the AC module.
thanks for sharing, what does the mirror puddle lights do then? when you lock the car and the mirrors fold in the lights will stay on until the rest of the lights turn off?
There is a lot in the instrument cluster that can be enabled actually here is what I have found so far off the top of my head
