in this example 02 would be for "Blinken links Hellphase" and 00 would be "not active". here is a list that shows all of the functions that I have been able to correlate

Code:
02    Blinken links Hellphase
03    Blinken links Dunkelphase
04    Blinken rechts Hellphase
05    Blinken rechts Dunkelphase
06    Blinken links aktiv (beide Phasen)
07    Blinken rechts aktiv (beide Phasen)
08    Standlicht allgemein (Schlusslicht: Positionslicht: Begrenzungslicht)
09    Parklicht links (beidseitiges Parklicht aktiviert li & re)
0A    Parking light right
0B    Abblendlicht links
0C    Abblendlicht rechts
0D    Left high beam
0E    Right high beam
0F    Lichthupe generell
12    Nebellicht links
13    Nebellicht rechts
14    Daytime running lights
18    Brake light
19    Rueckfahrlicht
31    Ambience lighting
Amazing work Somnus,

You might already be aware, but based on my IDE05145-Light configuration code; I'd like to contribute the following function codes...

16 = Abbiegelicht links (Cornering light left)
17 = Abbiegelicht rechts (Cornering light right)
1E = Coming Home oder Leaving Home aktiv
46 = Versorgungsbedarf der LCM Module (Supply requirements of the LCM [Luminaire Control Module])

Hope it helps and I look forward to reading more...

Any chance the research above might find a way to enable the ambient lights to function as coming home/leaving home/welcome lights????????
Is the above just for the MQB platform?

So - I must apologize in advance to the contributors on this thread, but notwithstanding the very-clever work done on the "Lighting configuration hypothesis" - something is seriously amiss here: to be brutally frank (or, I can be earnest if you want) the numbers just don't stack-up (I think)

Let's start with the basics: in my Audi A3, IDE05145-Light configuration has the following setting (BCM = SW:5Q0-937-084-CQ HW:5Q0-937-084-CG;Component:BCM MQBAB H H36 0253):

Code:
0C 34 00 14 02 00 64 03 00 00 00 00 00 00 00 00 0C 3E 00 15 04 00 64 05 00 00 00 00 00 00 00 00 04 48 00 4A 08 09
1A 1E 00 1A 14 00 7F 06 00 9A 04 4C 00 4C 08 0A 1A 1E 00 1A 14 00 7F 07 00 9A 01 48 00 49 14 08 7F 1E 09 7F 00 00 
00 00 00 00 01 4C 00 4B 14 08 7F 1E 0A 7F 00 00 00 00 00 00 03 49 00 1A 0B 0F 7F 1E 00 7F 00 00 00 00 00 00 
03 4D 00 1B 0C 0F 7F 1E 00 7F 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 2E 00 00 04 2E 00 64 00 00 00
 00 00 00 00 00 00 02 37 00 1E 0D 0F 7F 00 00 00 00 00 00 00 00 00 02 41 00 1F 0E 0F 7F 00 00 00 00 00 00 00 00 00 17
 38 00 5F 12 00 64 00 00 00 00 00 00 06 00 80 17 42 00 60 13 00 64 00 00 00 00 00 00 07 00 80
Now, this code-string will probably appear on your screens as very long number - but according to MS-Excel, the Byte count =224. If I divide 224 by the suggestion that each Lighting configuration-set ("config-set") has been allocated 16 x bytes - I get 14 x lamps (or, 7 x lamps for each headlight fitting).

For most (all?) MQB platform vehicles, there is generally 35 x Leuchte-sets in total - and of these, there are indeed 14 x Leuchte-sets that can be considered as beloging to the front of the vehicle if the fog-lights are included. The fog lights should be included because sometimes the allied Leuchte-sets are used for the "all weather" lights, which are inbuilt into the headlight assembly.

So far so good - but:

As we are all aware, each Leuchte-set has 19 x adaptation channels. So, the hypothesis thus far postulated begs the question: how are the 16 x Bytes in the config-set allocated to 19 x adaptation channels in the Leuchte-set? Or, asked another way - which 3 x adaptation channels don't have a matching Byte in the config-set- and why?

There is an obvious answer for one of the Leuchte-set channels: Lichtansteuerung HD AB is really only useful for the rear lights because it determines what happens when the hatch is open/closed. Clearly there is no need for a Byte in the config-set to mirror this channel setting because for the front lamps, the value is always set to "Always". This leaves 2 x channels per Leuchte-set without a corresponding config-set Byte - any ideas?

Don

PS:
Edit: Dimming Direction (maximize/minimize) is encoded in the brightness byte, as far as I see. Everyting below $80 is "maximize" (0-127 [$00-$7F]). Everything from this value on is "minimize" (0-127 [$80-$FF]). At least this is what I consider when looking at Somnus posted configuration for the DRLs - I suspect they turn while signal indicator is active on that specific side...?
@TBAx - again my apology, but in trying to apply the stuff already suggested in this thread to the Leuchte-sets in my Audi - I'm fairly certain that the Byte value 9A is the code for minimize. As support for my contention here is an extract from an early post from Somnus

I zeroed out the following lines for Leuchte4TFL

Code:
01 3A 00 49 14 00 7F [B][U]06 00 9A [/U][/B]08 09 7F 00 00 00
which disabled the dimming when the turn signal was activated (06 00 9A), and the Parking light and Side Light (08 09 7F).
On my Audi - DRL wink happens on Leuchte SL VLB10 and the associated command Blinken links aktiv (beide Phasen) is placed on the Lichtfunktion GH pair - so the "minimze" setting happens further down the Leuchte-set than in Sonnus's case. Here is the comparable Byte-string on my car for Leuchte SL VLB10:

Code:
04 48 00 4A 08 09 1A 1E 00 1A 14 00 7F [U][B]06 00 9A[/B][/U]
Notice the same pattern, ending in 9A-which I suspect is the code for minimize (I think)

EDIT: and my hunch (albeit said with much less commitment) is that "maximize" has the code 00

2B	43	allgemeine LED
2C	44	LED Fußraum- oder -Innenleuchte
2D	45	allgemeine LED bis 6W
2E	46	LED Kleinleistung

So, with the combined wisdom of contributors on this thread and the tables above, it's now relatively easy (with MS Excel) to re-create the Leuchte-sets from the Light configuration channel values - and presumably, to change the values on the LCM s - all I need to do is to get a LCM car into the workshop!!!

Kudos to all contributors!!

It seems that you all are warmed up now and already bored.

Now, find out how the rear lighting configuration is encoded in MLBevo BCM2 units...

hadez16: I bow to your superior knowledge of the MLBevo BCM s. - I've not had one of these in my home workshop. But I respectfully suggest that the Light-configuration channel hypothesis for MQB platform vehicles may need modification when applied to these type BCMs (if the hypothesis applies at all).

The reason for my hesitation has been prompted by a very brief overview of your channel setting which I re-paste in column form below (note: the first row is the Parametergruppe number):

Restructuring the hex-pairs as separate rows (as above) indicates that there are 255 x hex-pairs in each adaptation channel on MLB platform vehicles. The MQB hypothesis says that each Leuchte-set is described by 16 x hex-pairs.

Alas 255 divided by 16 doesn't equal a whole number - so something is amiss IMO. But, 255 divide by 15 = 17 (which is a whole number)

Perhaps MLB platform vehicles don't have the reserved channel that appears to apply in MQB platform vehicles (I'm guessing of course)? The other niggling doubt about 17 x Leuchte-sets to describe the taillights is that it's a non-even number. But, at least for MQB platform vehicles, Leuchte27NSL RC6 controls 2 x lamps (on each side of the car) - does this happen on MLB vehicles?

Finally - why is it necessary to use 255 x hex-pairs x 10 = 2,550 hex pairs? - why 10 x channels?

I just saw that this is a sticky now, and all I can say is you guys took a hunch I had (and a hunch others shared as well) and turned it into a whole new way to look at MQB light configuration.

The collective knowledge in this forum is staggering.

hadez16: I bow to your superior knowledge of the MLBevo BCM s. - I've not had one of these in my home workshop. But I respectfully suggest that the Light-configuration channel hypothesis for MQB platform vehicles may need modification when applied to these type BCMs (if the hypothesis applies at all).
...
I'd suggest that the MLBevo lighting configuration could work similar to the MLB lighting configuration in those BCM2 units (upper adaptation channels).

I think it's clear that MQB principles will not apply here.

It was more or less a little joke from my side ;)

Mad props to all of you here!
