Left fog light flickering!

[BladeX5]

Hi all,

I'm having troubles to find where the problem is. My left front fog light started giving me warnings about a year ago. In the very beginning it was a burnt bulb, I changed it, but after a few weeks, I had this cluster warning saying to check fog lights, but they were fine, at least I thought that, however after living with this warning for several months I went to check everything I could. Removed LCM and cleaned it very well with contact cleaner, removed fog housing and bulb and changed it for another brand new, because I found the cable of the H3 bulb a little burnt, like when it overheats or by false contact, so, cleaned everything, made the plug enter very tight so no play and changed the bulb as I said before. Went to lit the fog lights and the warning is still there. At this point I noticed that the front left fog light is flickering (incandescent, not led) just a little bit, barely noticeable, so I assume that's the whole deal for the warning. The problem is that I've no idea what's wrong. Anyone had have this issue before?

Thanks to all.
