Hi. What could be possible cause of inner boot (l/h uk) led lights not working? Definitely not led it self co I’ve bought another one and it has same issue. My fog lights and reverse lights does work but led strip don’t have positive connection for some reason. I found the loom going to boot and cable not snapped. What your thoughts about it ? Hope so you understand my issue, did research here and couldn’t find anything

Didn't pre LCIs have an issue with the rear light ground wires corroding and/or burning out? It's been a problem right back as far as the E9x as well as I understand. I would start my investigations there. My brother in law had rear light problems with his 2014 F31 which was caused by said ground wire issues.

If you have a scan tool, give that a look as well in case it's a module that isn't happy rather than a wiring fault.
