Wired to BCM, coded, separate circuit, adjustable brightness with slider control, independent from other background lights (door, footwell, etc.), coming&leaving home logic.
Parts
- Extra thin LED strip (White 6500K),
- BCM terminal,
- Isolation tape, wires, zip ties, connectors...
- Diagnostic computer (VCDS, OBDeleven, whatever... ),
- Torx key, flat driver, prying tools, terminal crimping tool cutters, precise knife...
- disassemble center console and install LED strip
- find empty Leuchte BCM channel by checking module 09 adaptation channels
- wire ground to ground, positive to BCM
- adjust coding and adaptation values in 09 and 5F
- enjoy!
- Making sure that MIB (infotainment unit) is ready for slider controls. If you have door lights or footwell lights you most likely already have this.
Code:Module 5F → Adaptation → Car Function list BAP Gen2 → Interieur light 0x08 → Activated Module 5F → Adaptation → Car Function list BAP Gen2 →Interieur light 0x08 msg bus → Comfort data bus Module 5F → Adaptation → Car Function adaptatations Gen2 → menu display ambient illum. → activated Module 5F → Adaptation → Car Function adaptatations Gen2 →menu display ambient illum. over threshold high → activated
- Enable slider on the infotainment screen, adjust brightness change calculation parameters
Code:Module 09 → Security Access → 31347 Module 09 → Long Coding → Byte 17 → bit 2 (Ambient Cupholder Lights) → installed Module 09 → Adaptation → Interior light, light configuration → Cockpitbeleuchtung → installed Module 09 → Adaptation → Int. light, 2nd generation → Aufloesung dimmzeit → 0.1s Module 09 → Adaptation → Int. light, 2nd generation → Helligkeit Cockpitbeleuchtung nicht berechnen → not active
- Set the LeuchteXX channel (where XX is the channel number that you have selected to use)
Code:Module 09 → Security Access → 31347 Module 09 → Adaptation → LeuchteXX → Lasttyp → 46 - LED Kleinleistung Module 09 → Adaptation → LeuchteXX → Lichtfunktion A → Ambientelicht 2 Module 09 → Adaptation → LeuchteXX → Dimmwert AB → 100 (%) Module 09 → Adaptation → LeuchteXX → Lichtansteuerung HD AB → Always
- Adjust slider maximum brightness (
0x14 = 20 DEC
. Maximum here is0x64=100
which is way to much for it to use it at night)
Code:Module 09 → Security Access → 31347 Module 09 → Adaptation → Interior lighting, parameter → P adaption kundenwunch cockpit → 14
- Adjust brightness change delays (set all to
0
for instant reaction)
Code:Module 09 → Security Access → 31347 Module 09 → Adaptation → Interior lighting, parameter → P t * cockpit → 0 (s)
- Link one of the events to the slider (
126%
is magical)
Code:Module 09 → Security Access → 31347 Module 09 → Adaptation → Interior lighting, parameter → P helligkeit Fzg geschlossen zuendung ein cockpit → 126%
- Adjust brightness level on all other events (
25%
is enough for this LED strip but if your is dimmer you can increase this)
Code:Module 09 → Security Access → 31347 Module 09 → Adaptation → Interior lighting, parameter → P helligkeit * cockpit → change all with default 100% to 25%
- Adding wiring to BCM
- Disassembling center console
