Hi
Back with "How does...?" questions. :)

This time I'm trying to figure out how does the LED light work in A8 D3-chassis. What kind of "info" does move in bi-directional wire?
Problem is that the light is sometimes at 100%, some other times it works as it is supposed to. Weirdly the problem doesn't move sides when i swapped L and R light. Wires check out.

Now i don't have autoscan from this vechicle, because the latest VCDS update doesn't like to finish the autoscan. - I've contacted Eric already.
