A6 4G Cornering Light Coding

Hi.

Are there specific contexts in which this encoding (byte 4, bit 1) works, but not in others?

I have two 4G headlights, both with "Xenon plus," which means "straight-beam xenon headlights, WITHOUT a turning function, but WITH all-weather lights."
They both have the same BCM (Baseband Controller Module), the same hardware, and the same software.

One of them (Moni) could be easily programmed with the "turn signal over fog lights" function, while the other (Günther) could also be programmed, but hasn't been.

I changed the "40" in byte 4 to "41".

Moni:

I can provide complete auto scans, but it would make this very long.

Therefore, "identical" is not the same. What would be interesting are the differences...

Okay.

Then I need to clarify what I meant by "equal," because I meant:

Code:

Teilenummer SW: 4H0 907 063 BF    HW: 4H0 907 063 F    Bauteil: BCM1 2.0      H12 0100

and also that "here", because I still need to go to one of the trekkers .

Byte 5: Changing the value from 74 to 34 indicates that FLA is installed (and has more instances than necessary, where applicable).
Byte 8, changing from 84 to 8C, indicates the air suspension system (which is present where it should be, but not where it's missing).
Byte 12: Unfortunately, VCDS does not have information on this.
Byte 18: Unfortunately, VCDS does not have information on this.
Byte 20: Unfortunately, VCDS does not have information on this.
