Help retrofit full LED headlight on Polo 6C
Posted: Mon Sep 01, 2025 7:34 pm
Hello everyone
I'm Marco from Italy and I'm retrofitting the original LED headlights on a Polo 6C 2014 MY 2015 with HIGHLINE bcm ( 6C0937089E )
I'd like to ask why, when I connect the headlights with the 10-to-14-pin adapters without coding, the side lights don't work, while all the other lights work. I can get the DRLs to work with the T14 PIN 12 contact if connected to the battery, but I only get high light intensity on the DRLs and can't set them to low intensity.
Anyone to help me?
My adapter with T14 Pin 12 and T14 Pin 14 not connect to bcm
