UK-POLOS.NET - THE VW Polo Forum

There is no rush. Thank You for Your kindness!
I assembled all back. I can drive the car.
I checked the wiring diagrams also for 8ih and everything seems ok.

Based on the posted autoscan:

Try this new BCM coding, and tell me the results.
640000380C21000000280CC12C4B84D4B000654E60021040300000020000

It may be necessary to make more attempts.

Please, post the autoscan with the changes made, ...for example, if you have installed the SCLs, post the autoscan with the changes in BCM coding before I have to ask for it. Thanks

What is the reference number of your light switch?

6Q0941531N
I tried the coding and still not working. Here is my new coding with SLC.

It is likely that the problem with your DRLs is the light switch (I already know that you have 12v in pin3, but ...)

Now I cannt do the relevant verifications, tomorrow I'll tell you something about it.

SCLs coding it's right.

... hard obsession with activating Byte23 Bit0 ...
7E0 BCM don't need this coding with your electrical installation (without automatic lights).

What you do with this coding is to activate pin 1b for 58 signal and pin 1a to activate 56b signal automaticaly. (yes, 56b low beam, not 56a high beam)

You already have the 58 signal in pin 4b (and other pins), and since you don't have automatic lights the 56b signal management (low beam) is according to your wishes (manualy ) and the subsequent management by the BCM through the 2a and 2b pins.
Therefore, it is not necessary to activate Byte23 Bit0.

Without this coding (Byte23 Bit0 unmarked) 1a and 1b are used for high beam, but with a very different electrical installation. Like those of the VW T6, last Amarok model and other recent PQ25 models with a high level of equipment.

Perfect, we have already tested the two possible codings for Bixenon headlights in Amarok. (codings with 7H0 or with 7E0 BCMs).
Both have been accepted.

Increase the chances that the problem is the light switch.

....

Have you installed the CCS or are you testing?

7E0 BCM don't need this coding with your electrical installation (without automatic lights).

What you do with this coding is to activate pin 1b for 58 signal and pin 1a to activate 56b signal automaticaly. (yes, 56b low beam, not 56a high beam)

You already have the 58 signal in pin 4b (and other pins), and since you don't have automatic lights the 56b signal management (low beam) is according to your wishes (manualy ) and the subsequent management by the BCM through the 2a and 2b pins.
Therefore, it is not necessary to activate Byte23 Bit0.

Without this coding (Byte23 Bit0 unmarked) 1a and 1b are used for high beam, but with a very different electrical installation. Like those of the VW T6, last Amarok model and other recent PQ25 models with a high level of equipment.

Well, my thinking was, parking lights work so clearly the PWM signal for T14/12 is working and power supply T14/10 is working too.
So somehow, I thought, DRL was not coded or incorrectly coded. Therefore my thoughts about byte 23 bit 0 and bits 3-4.
Thaks for clarifying!

The CCS is installed but it is not coded in that coding.
I don’t have the necessary voltage on headlight pin 10.

I think the problem is with the modified headight switch T17/16 wire versus the T10/10 wire.
Something with the terminal 58d.

I think T17/17 wire must be joined with ex. T17/16 wire (the one to bcm T73b/4 which is removed from my light switch).

As I told you, this is the only and correct way for the T17/16. This is indisputable.
viewtopic.php?f=56&t=70902&start=60#p530843

Your original installation is an extremely economical way to connect all 58 signals (except taillights)... all joined via a single wire of the light switch, T17/16, and this is useless in case of: (any of these conditions)
1- Dimmer.
2- Bixenon led modules for parking/side lights and DRLs.
3- Led license plate lights.
4- Auto lights
etc...

Some can work with your original electrical installation "doing tricks in the coding", after all, the 12v power is there, but they aren't managed by the BCM, ...but other necessarily need a BCM control and it is necessary to differentiate these signals individually...

???
T17/17 is already attached to T17/16.

its only function is to illuminate the light switch. (like other interior switches of your Amarok)

- There is no T14 here.
- bits 3-4 not related to this problem.

Yes, I have checked my wiring and You are right.
