Facelift xenon retrofit (AFS, dyn. & static cornering)

[Roy_01]

No then you can leave it that way.
Try to pull out pin 13 and see if the cornering lights stop working.

Thanks for your help! Will try!

Hi Roy_01 (or anyone else that could help ),
I have installed Bi-xenon pre-facelift headlights on a 2011 scirocco updating the halogen ones. I have also updated the BCM to highline one (...87), installed AFS module and the proper wiring according to wiring diagram provided in this topic. With the VCDS I coded the following (as you have suggested in one port earlier here) ...

Byte 14 bit 3 check bi-xenon with shutters installed
Byte 19 bit 0-3 headlight dimming (bulb extended lifetime) change to inactive
Byte 17 bit 2 check bi-xenon without additional high beam installed
Byte 25 bit 2 check high beam via shutter active/installed
Byte 15 bit 6 check drl via seperate lights active
Byte 27 bit 2 check drl module for parking lights installed
Byte 24 bit 7 check drl as position lights active

then I executed the Headlight Adjustment and finally checked for any errors. While I did not get any errors, I have not got the static cornering lights functionality. I have connected the 13 pinout of the headlights to T52a/5 and T52c/46 of the BCM. Do you have any ideas of what is missing to enable this functionality/ or suggestion to debug?

Module 09:

Byte 14 bit 7 Cornering lights via front fog lights active is turned off. (Unchecked)

Byte 17 bit 0 adaptive light (checked)

Module 55:

Byte 4 bit 1 Dynamic cornering light active (checked)

Thanks Roy_01 for the response. For the first two option I am already ok. Regarding the AFS module I think I did not have the option for any coding. I am not sure if it is due to the fact that I am using a different AFS model (8P0907357K - chosen that one based on ETKA) or if it is a VCDS issue. I will check again and provide screenshots for better insight. BTW do you think that I can edit this option via VCP?

[Roy_01]

That AFS is not correct, cornering lights are operated different on that one. Not by can-bus if im correct.

[tel_scirocco]

You seem to be right. In this AFS module you do not have the coding options as you do in the 5M0907357 ones. You can only configure the car type using the "Software Coding" value and no other settings are possible. So as you guessed, the cornering lights on the pre-facelift Bi-Xenon (with 8P0907357 module) are operated without can-bus ... perhaps directly from BCM. For confirmation, could someone else with pre-facelift Bi-Xenons check which AFS module is using?

[tel_scirocco]

All that time I hadn't checked the lights outside the cabin and when I did that yesterday I noticed that both static cornering lights (left + right) switch on when I turn on the high beam. In other words static cornering light operate together with the Bi-Xenon shutters. So the issue after all is that my BCM outputs (T52a/5 and T52c/46) for static cornering lights are configured (somehow) as high beam operators.
Following Roy's suggestion on one of the previous posts, I switched on and off the Byte 25 bit 2 (high beam via shutter active installed) but it did not make any difference. The "Read configuration" via VCP shows that cornering lights are with C43 and A2 outputs on BCM that is different to what I see in the VW wiring diagrams.



Should I try and use the outputs C43 and A2 or it does not make any sense?

What bcm do you have?

[tel_scirocco]

I have one with the following code 5K0 937 087 R. It came from a Scirocco R.

[GeorgeAdams1!]

I think this have another pin outs cause it has the turn signals into the headlight. Not sure though. I think you need the one that end in 087 AB

[Roy_01]

What happens when you:

Byte 14 bit 3 uncheck bi-xenon with shutters installed?
Byte 25 bit 2 uncheck high beam via shutter active installed

Try different combinations and see what it does. Also be sure headlight switch is in auto position.

C43/A2 put is listed as undefined in the pinout list.
And also with VCP you can’t check cornering light function I see? Only in module 09 i think.

Byte 17 bit 0 adaptive light (checked)
Try to uncheck and test what it does

Hi guys,
I have install bi-xenon lights and AFS and everything working fine. Now I want to install DCC suspension, so the questions are:
how I should connect rear sensor?
Should I change it to sensor with green plastic?

I checked Elsa, but it show that to AFS and DCC it's the same sensor, but wiring is different. So I don't know what way is right..

Roy_01 you are right. C43 and A2 are listed as undefined in the wiring diagram documentation. I also cross-checked that on BCM... there were no pins. Anyway, after spending several hours testing BCM settings using VCDS, I finally managed to make cornering lights work as expected. I needed to experiment with every single bit on long coding (even the ones that did not have a description) to find the working compination.
First of all I needed to have unchecked Byte 17/ bit 0 - "Adaptive Light/Cornering Light Variant (0 = Cornering Light / 1 = Adaptive Light)" since I have the static cornering lights (pre-facelift headlights). Additionally, I needed to have checked Byte 17 bit 2 - "Bi-Xenon without additional High Beam" (when this was unchecked the cornering lights turned on with high beam). Finally, Byte 14 bit 6 needed to be checked. I haven't managed to find a description for this setting but it seems to enable the functionality for static cornering lights (at least on my BCM).

I checked Elsa, but it show that to AFS and DCC it's the same sensor, but wiring is different. So I don't know what way is right..

I am not sure if the sensor needs to be changed but for sure the wiring is different. With DCC installed, wiring of both front and rear axle sensors end up in the DCC control unit (nothing goes to AFS). The AFS module will get the sensor data needed to operate the headlights via the Can gateway (where it is already connected).

yes, you right, thanks! now I have error in AFS, failed rear sensor. I tried different coding, but it not help

[tel_scirocco]

Which module do you have? 5M0907357 or 8P0907357? If it is the 8P0907357 you need to make sure that you have as software coding value 0000016.

[savvaandrey]

I have Module 5m0 907 357 F

Problem solved!
The right coding for DCC + AFS: 0A3200000B000200
