Successfully installed and coded the Euro spec LED tail lights to my FL 2018 Golf wagon.
A bit of background info: the N/A & Canadian face-lifted (MY2018) have the new LED tails, with the brake and turn signal combined with red color in typical Big3 fashion of yesteryears. Didn't like it, and set-off to procure Euro tails for the retrofit.
I did the outer tails only as I didn't care for fog light. Needed was the outer tails, new adapter harness and coding. (Same procedure I assume for the regular Golf/GTI/R)
OEM Euro Tail Lights:
- Part # 5G9-945-095-E (left) & 5G9-945-096-E (right)
- Harness (from user ZERO815)
