Euro Tail Lights#

I’ve always preferred amber turn signals over flashing brake lights in my vehicles. My 2010 JSW had them but my 2019 Alltrack lacked the amber turn signals.
I bought my 2019 Golf Alltrack SE with the Driver Assistance and Appearance Package. It came with North American Region LED tail lights (not sure if this is a standard feature of 2019 models or only for vehicles with the appearance package) so when I bought the EUR LED kit I had to take this into account when choosing the wiring harness. Even with this choice I still had to make modifications to the harness before installing, which I’ll go over below.
Items purchased:
Mk7 European Light Switch 5GG941431D
Chinese switch (works fine)
Auto Lights: Yes
Front Fogs: Yes
Rear Fog: Yes
OEM Euro LED Tail Lamps 5G9945095G 5G9945093L 5G9945094K 5G9945096G
Do you need an adapter harness?: Tail lamps and adapter harness
Rear Fog: 2
Style: 2018+ NAR LED to Euro LED, tinted

Euro Switch#

Since I’ll be installing new tail lights with fog lights I had to purchase the Euro light switch. Installation is very easy, at position 0 push in the switch and turn it towards Auto then pull it out.
Modify Harness#
Before getting to my car I had to make some modifications to four wiring harness connectors with an X-ACTO knife. It would have been easier to trim off plastic from the connectors in my car but I wanted to avoid irreversibly modifying anything in my car if I could help it.
On both outer taillight wiring harnesses I had to trim off a plastic key rail that was in the way. Since I didn’t have X-ACTO blades narrow enough I had to sacrifice the guiding rail right next to the key rail. Thankfully the connector still fit snugly with no play. For the inner harness connectors I had to remove one key rail but ended up having to sacrifice a second key rail.
Tip
Before removing any taillight I suggest checking if all the wiring harnesses connect to the new lights and your car’s connectors.
Outer Taillights#
This is the easy part. Installing the outer lights is as easy as:
Access the taillight connectors by removing the felt covers in the cargo area.
Unplug the existing connectors.
Remove the plastic screw with your hands by twisting them off.
Pull out the old taillights and install the new lights.
Connect them using the modified outer wiring harnesses.
My passenger side taillight fit fine and flush but the driver side seemed to stick out a bit. I fixed this by turning the plastic adjustment screw with a T15 bit and ratchet.
Inner Taillights#
Since I bought taillights with two fog lights (one for each side) the included inner wiring harness came with two wires connecting the two. This means the two inner lights will connect to each other with these two wires that must be routed behind the inner plastic body trim. If you didn’t get fog lights and only received the outer lights with the amber turn signals then you can skip this section.

First remove both taillights by removing the plastic access cover and using an 8 mm hex socket. Each light has two nuts that need to be removed. Then you can remove the lights by pivoting them away from the center of the tailgate. Install the new inner taillights in the reverse order and tighten the four nuts.

You have a couple of options when wiring the inner lights. You can take the easy route and follow the included instructions, which is to blindly snake the wire and harness from one side to the other using the access panels for the inner lights. I didn’t like the idea of a wire being loose back there so I went with the slightly (but not much) harder route and remove the hatch inner plastic trim to get a complete unobstructed view of where the wire will go.
I ended up zip tying the harness wire to the existing wiring in the hatch. I then put back all the body trim pieces.
Coding#

Without coding the wrong lights will be designated as brakes and blinkers.#
The final step is to apply coding so the right LEDs light up when braking or signaling. The instructions given were for VCDS/VAG-COM but all I have is OBD11/OBDeleven. Luckily the settings are very similar. Set aside 20 to 30 minutes to do all the coding. You’ll need to write changes before tapping “Back” since OBD11 doesn’t queue up new settings.
To start you’ll need to enter an access code to enable writing:
09 Central Electrics
Security access
Login code: 31347
Tap “Enter”, it should say “Verifying login code” then “Success”

The next step I believe is to enable the rear fog lights to work with the Euro switch I mentioned above.
09 Central Electrics
Adaptation
Aussenlicht uebergreifend (search for “ueb”)
LDS mit Nebel Schlusslicht
Set to Yes

Finally it’s time for the main event; grab some coffee for this. Go through each setting and either make the change or verify the settings match the values below:
