@distrub: Hi.

Here is a better view of the BCM long-code string from the auto-scan on your first post:

ByteHex    Binary
0    00    00000000
1    1B    00011011
2    13    00010011
3    46    01000110
4    C2    11000010
5    41    01000001
6    22    00100010
7    FB    11111011
8    0F    00001111

11    00    00000000

At the risk of boring everyone by repeating the stuff in @downtime link (Godfather? - I think not - I definately prefer horse-heads to remain attached to their bodies ) , the important software switches for DLA headlights for the BCM are on Byte 2, Bits 0-2.

As you can see from the values above, your BCM value for Byte 2 = hex13 - so, Bits 0-2 =hex03. If you look the LCH screen on the @downtime link, you appear to face exactly the same problem as @cdr38 (i.e. he/she also had a BCM where Byte 2, Bits 0-2 =hex03)

So, as a suggestion - try the same solution as in @cdr38 case; change Byte 2, Bits 0-2 to hex 06 . For your BCM, this means that Byte 2 = hex16 after the change.

After making the change, clear the DTCs and see if the problem is solved. If errors persist, and given the similarity between the equipment types in the auto-scans for the 2 x cases - you may need to tell the BCM to NOT control the shutters (i.e. the hex55 module may do this in the new headlight fittings - as in @cdr38 case), So, perhaps @cdr38 solution for Byte 06 might also be worth trying; set Byte 6, Bits 5-6 =hex0. This means that Byte 6=hex02 after the change.

And finally, to complete the disabling of the headlight shutter control by the BCM - the last part of @cdr38 solution is also worth a shot; shut-down the 2 x Leuchte-sets for the Shutters in the BCM

Hi. Thanx for the tips. But non of this works. My BCM will not accept Byte 2 = 16. Got 3 choises on Bits 0-2. Its 00,02 and 03
Isnt my new headlights highbeam Bi-xenon? So its controlled by the hig beam shutter?

Il s'est mis au feu de route. Donc, je vois quelle est la différence dans les valeurs des adaptations.

cool!

Maybe you misunderstood me. I did not get my highbeam to work. The post you linked to, that guy had his high beam in working order. I cant understand what I need to change in my adaptions value to get it right.

me too, during the modification I had only three choices that I could select on bit 0-2 ...
I then entered the coding directly into the line of code and it worked...

I love you man. This worked like a charm. Entered the HEX 16 right the line og code, and it was accepted by the ECU. Now my high beam works again.
Thanx alot. after many hours of trying and failure, this was the easiest fix.
Thanx for all the good help her :-)

Peut-être que vous m'avez mal compris. Je n'ai pas fait fonctionner mes feux de route. Le poste auquel vous avez lié, ce type avait ses feux de route en état de marche. Je ne comprends pas ce que j'ai besoin de changer dans la valeur de mes adaptations pour bien faire les choses.

Je t'aime mec. Cela a fonctionné comme un charme. Entré le HEX 16 à droite le code de ligne og, et il a été accepté par l'ECU. Maintenant, mes feux de route fonctionnent à nouveau.
Merci beaucoup. après de nombreuses heures d'essais et d'échecs, c'était la solution la plus simple.
Merci pour tout le bien de l'aide :-)

Merci a Don
