Where various lights come on unexpectedly I’ve found it’s poor earths, If you have the wiring diagram , the colours very simple to identify so it would have been either live or negative issue . So remaking the earths around the front grille...

If in doubt, check the earth's

Will it make a difference as I haven’t done anything to the earths, my front left indicator wasn’t working so I wired it in with the back left and then my problems started?

My full beams are bringing on brake lights along with fog light and full beam, dipped beam isn’t doing anything, need help urgently as I’m dying to fix it
