Thought I'd drag this thread into 2014. I recently fitted OEM S4 Xenon headlights, and as already stated here they worked with no coding required.
However, 'working' seems to be limited to just the fact they turn on and off when they're supposed to. I just discovered the level adjuster doesn't work at all. Which looking at the info Woorlord has provided seems to make sense, given that the Xenon units are supposed to be auto-levelled, not manually adjusted.
I've got a feeling I already know the answer to this, but does anyone have an idea how much of a pain in the **** retrofitting the auto-level sensors would be?
If it's a unanimous, "MASSIVE" pain in the ****, then I guess the way to go will be to try rigging the servos to work with the manual level control? Something that hopefully won't involve irreversibly ruining them if they ever need to go back into an auto-levelled car? :/
Thanks
