I have succesfully retrofitted Xenon with cornering lights, but what I am puzzled about is that they don't always self-check when I turn them on? You know, go down then up? Sometimes they just turn on fixed.
I've been checking a few times readings with VCDS when they don't do the self-check, and didn't notice any errors. Measuring blocks from sensors were OK, testing it through VCDS (lower position, outer position, inner position) was also OK.... Also I tried sitting in the bunker, or adding power while holding handbrake, and they lower OK. Also, every time they didn't self-check, cornering was working fine...
So basically I don't have any problem just that I don't know if that's normal or not... When are they supposed to self-check and when not? I guess they aren't supposed to check if I turn them on while driving?
