Could possibly be the engine bay fuse box, I had both dipped beams go out (bulbs were fine) side lights and full beam worked along with everything else even the symbol on the dash worked, turns out it was a relay on the fuse board…… but the fuse board is a sealed unit soooo needs replacing the whole thing a new one from neo brothers was £160 ish but mine is a 2013 so will probably differ to yours
