I wonder were I can get the wiring diagrams to compare the euro taillights to the na taillights because then maybe i can see if it would be easy to rewire the taillights, though I have a feeling a new wire would need to be ran to the bcm to make these behave like the euro ones.
    Seems in order to make these taillights act like they are from Europe I would need to completely swap them out for the European version. The circuit for the blinkers in Europe they turned into the side markers here in the US and then changed the circuitry in the taillights to tie the brake and blinker together. There is absolutely no way to circumvent this through coding. I already priced out taillights and for a used set it will be like 400, which isn't bad.

    Is there any way to adjust brightness of rear LED turn signals on B8 Avant FL? I changed LEDs from red to yellow and they seem to be to dark.
