Xpower:Hi. Very interesting problem - thanks for posting
I'm not sure if you are aware, but a few of the forum's "Leuchte-nerds" have been discussing the question of the mysterious
IDE05145-Light configuration channel (in the ) on platform cars that are fitted with s -
here.
I have been purely an intellectual voyeur in these discussions - but the underlying hypothesis which has been developed by some very bright forum colleagues is that there maybe a correlation between the setting in this channel and the operation of the s.
The channel above has a value which is 448 x digits long - but mercifully reports these digits as 224 x hexadecimal pairs (the OBD11 device which I also use is not so quite so kind to users).
The new hypothesis postulates that the values in this channel are allocated as 16 x hex-pairs per Leuchte-set. So, 224 divided by 16 = 14 x Leuchte-sets
Anyway, based on my understanding of this very preliminary work, I have decoded the channel setting in your admap into equivalent Leuchte-set values in the spreadsheet which you can download
HERE
To explain the worksheet: This is all new stuff and one of the many aspects of the hypothesis that I believe still needs further work is to understand how the 14 x Leuchte-sets are allocated to the individual lamps in the headlight assemblies. I have done a similar analysis on a few vehicles now and it seems that this might vary with the model car, or/and the headlight type (I suspect). So, I have simply numbered each Leuchte-set in my spreadsheet 1-14, rather than guessing which lamp is controlled by which Leuchte-set. Nevertheless, it is clear from the entries in the "Leuchte function" column that the Leuchte-sets are paired for the right/left side.
In the final column of my spreadsheet which has the heading "Code", I have included the particular hex-pair from the channel setting that relates to each entry in the 14 x Leuchte-sets.
So - how might this information be useful for your wants?
Well, the first task (I think) is to identify which Leuchte-set is allocated to which lamp on your car. From my analysis- it's clear that 6 x Leuchte-sets in the Light configuration channel are not enabled on your car. And, it's relatively easy from the entries in the "Setting" column to divide the Leuchte-sets into left/right side using the "links/rechts" identifiers (where they appear).
Of the 8 x Leuchte-sets that are active:
- Leuchte-set #5 =DRL function (car side unknown)
- Leuchte-set #6 =DRL function (car side unknown)
- Leuchte-set #7 = Left-side, low-beam & high-beam flash
- Leuchte-set #8 = Right-side, low-beam & high-beam flash
- Leuchte-set #9 = Right-side, Parking Light & Single Side Parking Light
- Leuchteset #10 = Left-side, Parking Light & Single Side Parking Light
- Leuchte-set #13 =Left-side, low-beam
- Leuchte-set #14 =Right-side, low-beam
Looking through the list above and based on your explanation that the inner "angel eyes" on the car currently operate as "side-lights" (which I understand to mean "parking lights" in my parlance) - Leuchte-sets
#9 and
#10 appear to be encouraging candidates - maybe?
The second task is to determine how to change the programming. If you look at the "Leuchte function" column in my spreadsheet for Leuchte-set #9/10,
Lichtfunktion B is a possibility because its current value is
not active and because the
Dimmwert AB value is
127 (so, full illumination).
The third task is to decode the DRL Leuchte-command to the requisite hex-pair code for the light configuration channel - which is
hex14.
The fourth task is to identify where in the code string for
IDE05145-Light configuration channel to splice the new 2 x DRL commands:
- for the right-side lamp - CAREFULLY look for the sequence - 4B 46 00 7F - change to - 4B 46 14 7F
- for the left-side lamp - CAREFULLY look for the sequence - 49 46 00 7F - change to - 49 46 14 7F
Finally, a caveat - as I have already said, this is brand new stuff (for me). I'm just guessing!!!
