DIY: OEM Lighting Package (AFS Xenon) Retrofit
This is a do it yourself of a retrofit of Halogen to OEM Xenon with Adaptive Front-lighting System (AFS).
Warning: This is my experience and is for informational purposes. You are fully responsible for your own project, neither myself nor this website is responsible for what you do.
This is based on a North American Region (NAR) car. There are differences between the Rest of World (ROW) GTI’s. I will try to point out differences when I can, but you ROW folks may have do some additional research.
Why I’m Retrofitting: Back in 2014 when the MK7 GTI were hitting dealers you had to wait four months to order due to shortage of inventory with Lighting Package. I lacked the self-discipline to wait four months. For the last two years it was prohibitively expense to retrofit approximately $3,000 so aftermarket xenon was the way to go. However, prices have been coming down on OEM parts. I was able to procure all parts for $1,300. $300 over the initial cost of $1,000 for LP. I have been quite happy with my retrofit xenon; however, I wanted a smart lighting system that changes light direction based on speed, steering input, hills.
Parts:
Body Control Module: Determine if your Body Control Module (BCM) also known as Central Electronics Control Module supports AFS. There are varying grades of complexity of function in different BCMs. Using Vagcom to determine, my GTI SE has BCM part number has BCM 5Q0937087N. If you have an S with the lighting package you likely have this same part number. If you go into long coding and look at byte 2 you should see a choice of halogen or xenon. If that choice is not available, your BCM likely does not support. If you have an S you likely will have to replace the BCM. It is a $100 to $150 part used, but my understanding is to get re-keyed so you may have to take to dealer. I am not sure if this is only applicable to keyless entry, but I doubt it. You may have to do further research.
CAN Gateway Module: Determine if you have the proper CAN Gateway Module J533 to support AFS. This was a surprise to me. When I went to connect the AFS module to CAN bus I found that on my module pins 7 and 17 (CAN bus extended high/low connection 1) are missing. I connected to the diagnostic CAN Bus (pins 9 and 19) and although I was able to activate and program the AFS, lights do the shimmy up and down at start up and AFS module executes basic setting and acknowledge basic settings the AFS and cornering lights did not work and I had communication errors. The CAN Gateway Module in my 2015 SE is 5Q0907530S, but you need 5Q0907530AM (there are others, look at pictures and verify pins 7 and 17 are there) to support AFS. Check and order if you don’t’ have it is about $60 shipped used.
Headlights and modules:
Headlight for NAR market are 5GM941753A and 5GM941754A. I believe the NAR has the two yellow side markers. 8K0941597E xenon control unit, 2x 4G0907697 DRL Module, 2x Gas discharge lamp, D3S, 2x Bulb, H7 bulb, 2x 3D0941329 AFS control unit. I purchased my OEM headlights with all modules new for $990 shipped from GCP Tuning in Mexico. Last I checked they are $900 shipped on selling on eBay.
Rear Auto Level Sensor: 5Q0512521F or J. I purchased used off of eBay for $44 shipped. Third purchase was the charm; first purchase did not come with top plate, second never arrived. Make sure it comes with top plate. Some just come with mechanism and lower plate perfect if you broke sensor, but for retrofit you need both plates.
AFS Control Module: 7P6907357A I purchased used off of eBay for $80 shipped also from Poland.
MK7 AFS Wire Harness. I purchased from Aliexpress for $99 shipped. Decent quality and came with everything. Seen here: https://www.aliexpress.com/item/VW-A...608.0.0.xg2oNg
This cable is for the Golf MK7 and needed a couple minor modifications. A wire from pin 10 to B10 and B24 for other side is part of harness. On GTI the existing wire in harness already has that connection. Since I did not use the cable adapter and moved the wired from my existing 10 pin connector to 14 pin connector I removed the wire going to b10 and b24 on other side. Shell for connector going into AFS module is incorrect (it will not fit onto AFS connector); likely for AFS that is not with cornering lights. I replaced connector and shell part number is: 7M3-972-726-B. Available from the usual sources for under $10. Much easier to transfer wires over to new connector now rather than under the dash later as I did. You could also make by procuring connectors, pins/sockets, tape, corrugated pipe and wire for I estimate around $35. This guy made his own cable has part numbers for connectors and pins and sockets. http://www.golfmk6.com/forums/showthread.php?p=848059
Note: Kufatec.de and carsystems.pl carry modules and harness.
Miscellaneous:
You can use bolts and nuts to mount AFS Control Module; however, OEM is screws and capnuts.
4 x Sensor Mounting Bolts - N10430104 or M5 bolts, washer and nuts. OEM uses riveted cap nuts.
2 x 10 amp fuses – Micro size.
Roll of Tesa Adhesive Cloth Tape to integrate wires into harness.
Tie wraps for securing cable.
Process Overview:
You may want to familiarize yourself with schematic and process.
Run cable from headlights through firewall.
Temporarily install Headlights
Connect xenon shutter wires to BCM.
Make VAGCOM changes and check that lights function. Button up headlights.
If necessary, replace CAN Gateway, recode and have component protection removed, system aligned. This thread provides how to and contact informaton for remote On Line Diagnositc Information System. https://www.golfmk7.com/forums/inde...o-mib2-infotainment-conversion-part-1.343701/
Connect to AFS Control module wires to CANBUS, power and ground, and headlight motors. Connect +12V supply to headlights. Securely mount AFS Control Module.
Mount level sensor
Run cable from sensor to AFS control module.
VAGCOM changes to introduce AFS to CANBUS.
Adjust Headlight.
