I already posted a full scan for this wagon here:

I have acquired all the OE parts for a bi-xenon headlight upgrade and the conversion looms from Kufatec. The loom is annoyingly configured for LHD vehicles (as it assumes J519 is on the left side of the car) only so I need to extend or swap some wires if I want to keep the sense of left & right correct so that an option to enable corner/kerb lighting is maintained.
I will post all the part numbers in due course, but I was looking at the coding instructions supplied by Kufatec and wanted to check a few things as there isn't a fully documented view in VCDS for long coding of J519 - Address #09 - Central Electrics Module. Snippet below...
Address 09: Cent. Elect. (J519) Labels:. 4H0-907-063-V1.CLB
Part No SW: 4H0 907 063 BP HW: 4H0 907 063
Component: BCM1 2.0 H12 0111
Revision: 11012002 Serial number: 00000001287572
Coding: 690000108034A7E00905008300005F5FCF9DC70827080101000008402000
Shop #: WSC 02391 785 00200
VCID: 77BEEF70C6B560F2EA-8023
So the first thing to check is whether this controller is suitable for xenon conversion - 4H0 907 063 BP. I was thinking of just unplugging the halogen lights and trying the long coding for xenon config to see if coding is accepted or not. Then temporarily connecting the xenon lights with the adapter loom will allow me to check most functions before diving into the spaghetti hell where J519 lives in the drivers footwell.
As for long coding, the instructions will have the following impact on #09, but I don't know if these are 100% correct for a wagon with adaptive air suspension (AAS).
Byte 00: 69 --> 26
Byte 02: 00 --> 20
Byte 04: 80 --> 88 (or 89 for corner/kerb light mode active)
Byte 06: A7 --> 9F
Byte 14: 5F --> 1D
Byte 15: 5F --> 0C
Byte 27: 40 --> 60
Byte 28: 20 --> 21
This coding is for the NON-dynamic xenon headlights - the integrated fog light can be set up as kerb light during cornering but this coding is not for the whizzy turning dynamic AFS xenons.
This seems to line up reasonably well with a xenon equipped LHD 4G that found in the VCDS forum. That had some problems which I would put down to a difference in Byte 04 (which should be 88 or 89 instead of 40). All the other bytes relevant to headlights seem to line up:
Current Coding: 690000108034A7E00905008300005F5FCF9DC70827080101000008402000
OTHER Coding: 2600201040349FE08181008380001D0C0F9CC30826090101000004602101
The next challenge will be with the automatic headlight levelling controller (J431) - 4H0 907 357 A - which needs to be configured in a way where it takes information about suspension level from the CAN Bus instead of being wired directly to front and rear height sensors which a mechanically sprung 4G would use to determine the height of the car.
Is J431 coding well documented I wonder ?
