Hi there, I got it into my head to make a new modification on my Golf 7 GTI phase 1 of 2016. The modification would be to change the front optical blocks which are original in Xenon to Phase 2 style lights in Full LEDS. Link to Phase 2 LED lights: fr.aliexpress.com/item/32855010067.html?spm=a2g0o.cart.0.0.4290378dvUfwsf&mp=1&gatewayAdapt=glo2fraThe lights are adaptable to the front bumper of Phase 1. In addition, these lights are plug and play compatible for Golfs with the original halogen lights, which is not my case. Nevertheless, the seller specifies that he sells with the lights a Xenon to LED adapter at the level of the wiring harness of the lights. Until then, no worries. Come the purpose of my visit to this forum and this post regarding coding. Apparently, and for a person I contacted on the networks who made this modification, the vital functions of the lights, namely turn signals, dipped beam and light signature, work perfectly and without coding. On the other hand, the high beams need to be coded. From what I've been told, without coding, the high beams flash once but cannot be left constant. I therefore refer to you, who possibly had the solution or who have already carried out this mode which I grant you has not been done by many people, especially in xenon conversion to LEDs. Thank you very much for your feedback and for your help. Attached are photos of my Golf with all the modifications made so far.    |

chabalinou : Hi. Hmm...... first thing to say about your post is that these new headlights are non-OEM meaning that it's anyone's guess how they are designed and more importantly, how they are meant to integrate into VW's OEM CAN network. These third party suppliers of non-OEM equipment ALL advertise that their products are plug-and-play, but they seldom are !! So, with this caveat said and in respect of your high-beam question, the way that you tell a mk7 what type of main-beam system to operate is via the module that OBD11 calls central electrics. It really depends on the type of this module that is installed on your car - does our module have an active long-code string?
Maybe post-up details of the central electrics module showing the long-code (if present)?

First of all, thank you very much for your answer. Indeed I am aware that these are not original VW equipment and that necessarily their operation differs. I have read these various posts in which you participated and I am at the same stage. forum.obdeleven.com/thread/7206/led-high-beam-codingforums.ross-tech.com/index.php?threads/24271/I will need to get the coding done in order to code the high beams because as in the second post I sent you the high beams are not working properly However, in the post, no information is given on the action performed by P1xellat3d. I tried to contact him on social networks, unfortunately without a response. I'm sending you information from 09 central electrics today. I don't have the car with me at the moment. Thx for your help  |

Hello @dev52 ! I'm chabalinou's friend and I'm also working on the retrofit of facelift headlights on xenon lights. I made a complete extraction under VCDS of the module "09 - Central Elec." on my Golf 7 GTD (same configuration as the GTI of chabalinou). I thank you for your help because it is really hard to find information on the internet... Attachments:AdMap_Excel.xlsx (72.41 KB)

olivierbrt : Hi. Alas, ain't enough information in your spreadsheet - it's missing the admap header information (this issue is not just an adaptation channel matter)!! Also, from a headlight perspective, it may well be true that "my Golf 7 GTD" has the same configuration as "the GTI of chabalinou". However, do both cars have EXACTLY the same headlight modules - meaning the same module part numbers and the same module software numbers? And Golf mk7s/mk7.5s have many different factory installed systems for operating headlights. What precisely is the CAN configuration for the headlights in these cars - meaning do both these cars control their headlights via the BCM (J519), or do they use a Headlight Range module (J745)? And if the latter, do these cars both use Light Control Modules (A30/A27)? Don

Thank you for your quick answer ! Sorry I removed the header I did not think it was essential, so here it is: SW:5Q0-937-084-AJ HW:5Q0-937-084-AJ --- Cent. Elect. Component:BCM MQBAB H H18 0134, Coding:00170A42C24122FB4BE44000410C07281800000000000000000000000000 EV_BCMCONTI,013000,EV_BCMBOSCH_013.rod Friday,30,December,2022,18:38:27:00009 VCDS Version: Release 21.3.0 (x64) Data version: 20210226 DS325.0 VCID: 000F35079B030A8BC3-8054 I can't answer you about the CAN configuration for the headlights... How can I know?? I also send you the long coding of module 09 if it can be useful.  Thank you, Olivier |

hmmm......... no need for a separate screenshot of the long-code string for the hex09 module - this data is on the header information for the BCM admap! Why is the software version for VCDS so out-of-date - I hope that this is a legitimate Ross-Tech device?
Here's a more readable form of the long-code values:
Byte Hex Binary
00 00 00000000
01 17 00010111
02 0A 00001010
03 42 01000010
04 C2 11000010
05 41 01000001
06 22 00100010
07 FB 11111011
08 4B 01001011
09 E4 11100100
10 40 01000000
11 00 00000000
12 41 01000001
13 0C 00001100
14 07 00000111
15 28 00101000
16 18 00011000
17 00 00000000
18 00 00000000
19 00 00000000
20 00 00000000
21 00 00000000
22 00 00000000
23 00 00000000
24 00 00000000
25 00 00000000
26 00 00000000
27 00 00000000
28 00 00000000
29 00 00000000
So, the important software switches for this issue are on Byte 02, Bits 0-2 (remember that Bit positions on Binary numbers are read from right-to-left, so the right-most digit is Bit 0).
On this car, the relevant values for these switches are xxxxx010. According to my data, this means Xenon_AFS. If you look at the long-code helper screen for this Byte using VCDS, you should find descriptors for other headlight configurations. I assume that you are using one of the HEX-NET products, so you should have access to the "yellow" helper screens
As I have already said, I'm not sure how these non-OEM headlights are designed - so I can't recommend a suitable value. Try experimenting.
Also as I have already said - the other consideration in this project is the CAN arrangement for the headlight fittings on this car. You can see this arrangement in the auto-scan report. Specifically, you are looking for an operational module @ address hex55 and possibly Light Control Modules (LCMs) elsewhere in the scan list
