LED headlight issue after full exterior swap

[Mr Bean]

After installing a full set of LED exterior lights, my headlights aren't working properly. I was able to use my OBD MX+ to chang some settings in the BCU to keep the lights on, but now I'm getting a ground error fault on the right high beam...that light's completely out. I checked the fuse (supposedly F91), but weirdly, slots like 90, 91, 12, and 13 are empty with no fuse terminals. I had working beams before with halogens. How could they work without fuses? Any ideas?

@Mr Bean First off, I'd definitely double check those BCU settings you tweaked.
Sometimes, even though you're trying to make them stay on, those changes can conflict with how the system expects things to work, leading to new faults. You might need really specific coding for LEDs, not just a generic 'on' setting

Yes yes @Mr Bean if the halogens worked before, the BCU probably handled power differently for those circuits. Check the ground at the headlight connector and maybe try swapping in a resistor or a relay harness to see if it clears the error.
