MK7.5 OEM LED Headlights Retrofit

[wamba16]

I never fully understood how dla works, it activates liver at different speed
can you give more explanation please

 

[AWD4416]

DLA uses the camera on the windshield to manipulate the shutters in the high beams. It’s super impressive and there are a few videos in YouTube that show them in action.

I make everything from your coding … but I get errors … i retrofit from 8IT to 8IU

Please verify the connections on the 14 Pin connector. I just update some of that information.

Ok thank you … I resolve the problem … it was not correct xml files on my 4B module … in my 8IT was without dla and now my headlights is 8IU and was need xml

 

[Carolco]

Ok, gracias ... resuelvo el problema ... no eran archivos xml correctos en mi módulo 4B ... en mi 8IT estaba sin dla y ahora mis faros son 8IU y necesita

What xml files did you used? What model unit 4B do you have?

 

[Tarawsc]

What xml files did you used? What model unit 4B do you have?

As headlights are used they was have correct xml the problem was with the 4B xml my 4b doesn’t have dla … my 4b is just without letter in the end

 

[bams]

helo friend I have the same problem with the lights user leomaxe, light 081, module 399d and 572a,only traffic lights work, I have a 7 pin in the lamp plug, I changed the coding, spark plug, turn signals, parking lights, no dipped beam are

 

[wamba16]

can you share the XML file you used please and the reference of your 4B module, thank you

 

[doctor]

I make everything from your coding … but I get errors … i retrofit from 8IT to 8IU

such as errors caused by hardware, not coding.

 

[Tarawsc]

such as errors caused by hardware, not coding.

In my way I retrofit the 8IT to 8IU and after coding the problem is the xml on 4B module

At this point I’m really hopping you are committed. This is the point of no return and it will take some time to put the GTI (or whatever type of V-Dub you have) together again. This is the point where I lost my mind due to not knowing what I do now about this retrofit. It will take at least a day if doing it by yourself so plan accordingly.

The high level overview is: remove the battery, run wire harness, re-pin the new 14-pin connector, verify wire with multi meter, and the install headlights. I’ll put the connection info on the 4B installation post.

The first thing to do is remove the battery.

Remove the rubber strip from the plenum chamber cover. Then remove the two clips (3) holding the left side. Pull straight up on the cover to remove it from retainer (5).

Run the right headlight hardness following the yellow path. Run the left headlight hardness following the green path.

From the inside of the cabin, puncture a hole on the yellow part of this grommet to run the wire harness inside. I found a wire cloths hanger super helpful in this step.

Re-Pin the original 10 pin Halogen lights connector to the 14 pin LED lights connector. For the wires that are not used, cut them and put black tape or a shrink wrap sleeve on the tips. Then wrap them around the harness. Use some tape to wrap them to the harness. I cut and solder some of the wires since some of the pins in the 14 pin connector are smaller than the 10 pin connector. This is why checking the wires with the multi meter is extremely important. When putting the pins in the connector, try to reuse the rubber gasket to stop humidity/water from getting to the terminals.

Before removing the headlights, use tape to outline how they fit on the bumper. This helps in making the new headlights flushed.

Remove the two screws holding the grill in and pull the grill off. Point to think about, this will remove the radar from the car. However, since no real change has been made to the cars dimension, it should still be within specs after re-installation. Remove the radar plug.
*Since completing this guide, I have retrofitted the front assist camera. I can confirm that if the radar is removed while the battery is disconnected, there should be no issues with the radar if re-installed properly.

Remove the screws inside the wheel well.

Remove the screw behind the bumper holding the light.
Remove the bolts holding the headlight in place to include the metal bar.
I remember some screw/bolts I loosen up after removing the grill that allow me to pull on the bumper more so I can slide the headlights out.

Finally install the new lights and reverse the process to put everything back in place.

Hi !!!!, Ive been working on designing custom 3d parts for the MK7-7.5 series and printing the prototipes to test and make molds for production, its been a slow and expensive process, i have a 3d scanned golf tsi just like mine but its not high res, so theres a lot of try and error in the fittings, wich means going back to 3d, adapt and print again. those images on you coment, the CAD ones, it would be the best thing if I can get that CAD model !, with that I can make the parts perfectly from the begining and also the interior and custom engine parts !!!!, where did you got them ?

Thanks !

 

[Adurm]

@AWD4416 debating if i can do this successfully with mk7.5 LHD R lights into a mk7.5 gsw. I have vcds and traffic warnings, not sure about lane assist. Do not have vcp or odis. Could i be successful using your guide and not having vcp or odis?

Retrofit or just looking to upgrade the headlight? Easiest way is to just toss in an Helix/BEC/Osram or other aftermarket headlight that will connect to the 10 pin harness. The lights will be static, but you'll have dynamic turns and DRLs along with LED lights.

Retrofit it depends on if you're willing to make your own harnesses. Otherwise you're looking at something like this for the 7/7.5:
You'll need wiring, perhaps a new CAN Gateway and BCM depend on your current versions and pins. If those are good you'll need the headlight AFS module, headlights and their modules, perhaps a rear level sensor, and the new wiring between the BCM, CAN, AFS Module and headlights.

Doing a partial retrofit on my MK7 with Osrams and the VW Euro low line AFS module for auto leveling.

This is near exactly what I want to do. I have the aliexpress lights, but I'd like genuine ones.

I don't care about having any dynamic features, so I'm a bit confused by your above statement and would appreciate any help. Would I still need level sensors and wiring going to the rear of the car if I do not want any dynamic features? I just want OEM static LED replacements for my car that came halogen.
If I buy the headlight modules, and I am willing to make a harness, can I get away without swapping the CAN gateway or BCM?

Oem would be a xenon retrofit. I don't believe we have NAR led headlights.

For LED you'd want a aftermarket light BECs or other. They are made to replace halogen lights and be plug and play.
