I'm curious what will happen if you change:
Lichtfunktion B30 --> inactive
Dimmwert AB30 --> 100
I am thinking that having Lichtfunktion B30 as "Dimmung Klemme 58xs" (which is the dimmer control) is overriding the slider in the MIB interface. And by setting the Dimmwert to 17, you are restricting the dynamic range of the slider in the MIB interface (i.e., the brightest it will get with the slider maxed out it 17%).
Pure speculation on my part, but it's worth a shot.
Then you've done something wrong; it's one of the easiest things to do on this car.If you are referring to the following....with those settings, the lights wouldn't even turn on for me.
Controller 09 - Central Electronics
16 - Security Access - enter 31347
10 - Adaptations
(8)-Interior light; light configuration-Fussraumbeleuchtung
Change value from ‘not installed’ to ‘installed’
(This puts the footwell light % setting in the infotainment system (under lights))
Still in Adaptations go to
(4)-Leuchte30FR LC72-Lichtfunktion A 30
Change this value from ‘not active’ to ‘Footwell light’ from the dropdown menu
Next go to
(1)-Leuchte30FR LC72-Lasttyp 30
Change this value from ‘not active’ to ‘18 – 2* 5W’
Next go to
(6)-Leuchte30FR LC72-Dimmwert AB 30
Change this value from ‘0’ to ‘89’ or whatever value you want up to 100 I guess (this is where we set the highest brightness level)
Ignore the coding, only do the adaptations; you'll get superfluous faults otherwise. This is the guide I followed to do mine and it all works flawlessly.
Post an adaptation map of your BCM. Which pin did you use?Everything works EXACTLY as it should EXCEPT the lights dim with the cluster light dimmer, not the MIB interface slider. Basically the exact same thing as OP msmetis, who never reported back if his ever was sorted out.
Dude, I figured out MIB2 swaps on entry level 2018--> in the USA and have wired more engine swaps than I can count, I don't think hooking up one wire to a BCM plus a body ground is challenging. This is a coding issue, and the coding you provided simply doesn't work. The coding OP msmetis does work, minus the dimmer.
Hogwash! The 2018s absolutely do support coding. There was a change in the coding structure starting with 2017, in which all long coding was moved into adaptation channels. So there's no more "long coding". But it's still all there in adaptation channels and works just fine.So it appears that Mk7.5 BCM's are quite different than the IWMTom's 2014 and Kevinlan86's 2015. This tells me that there is probably one or more more items in the adaptation settings that are probably different than your cars, which is causing my issues of your settings not working for me.
I may dig deeper into this or just live with it all functioning as is. Either way, it isn't all that bad the way it is. Until someone with a 2018---> confirms that those settings work as advertised on their car, this is what it is. If I do figure this all out, I will update the tread.
Thanks IWMTom, Kevinlan86, and southpawboston for your help trying to sort this out.
