But, .... you say that the parking lights work in all conditions ... I don't understand anything ...please, clarify!

The pin 10 must have 12V for the DRL.
The parking lights are working ok when activated. The leds are dimmed.

I insist

Isolate original wire T10/10 headlight connector.
Install new 0.5mm2 wire from T10/10 headlight connector to T73b/5 BCM white connector.

Right
Isolate original wire T10/10 headlight connector.
Install new 0.5mm2 wire from T10/10 headlight connector to T73b/6 BCM white connetor.



DRLs

Isolate original T17/3 light switch connector. Remove fuses SC26 and SC27.
Install new 0.5mm2 wire from T17/3 to T73b/29 BCM white connector.

Left
Isolate original wire T10/4 headlight connector.
Install new 0.5mm2 wire from T10/4 headlight connector to T73b/3 BCM white connetor.

Right
Isolate original wire T10/4 headlight connector.
Install new 0.5mm2 wire from T10/4 headlight connector to T73a/5 BCM black connector.

Please, answer my question:

What's the use of pin 10 of your bixenon headlights?

A- parking lights
B- DRLs

Both pin 4 and 10 are going in the led modules. The dimming is made by pin 10, 5V with parking lights on. Pin 4 have always 12V.

Good answer. hahahahahaha ...
Please laugh with me .... it's a funny moment.

So the use of pin 10 is for the parking lights, not for the DRLs as you said here ....viewtopic.php?f=56&t=70902&start=105#p530906

I'm sure of the wiring because the wires from BCM 73B/5,6 to headlights pin 10, I buyed from Carsystems and are mounted when I tried the first BCM.

Yes, but for the DRL to work, both pins 4 and 10 need 12Volts. I have tested this.

I can provide you 12v on both pins. Do you want them?

I don't understand what You mean.

by coding...

I'm waiting.
Sincerly I'm very happy with what I acheived until now with Your precious help. You lost a lot of time with this matter...Not many persons are like You.

Discovering the secret of Bixenon headlights retrofitting in Amarok 8K0, 8K1 is priceless.

12v both pins ... activate Byte23 Bit5.
This is not for the Amarok ... also activate the Byte21 Bit0 (to test).

(return to the previous coding if you do not find your desired results)

I tried on both codings (the initial and the last with no errors) and still no DRL.

Yes, it was the result we expect.

Today I will do some checks with respect to light switch reference number.
