The headlights left on warning buzzer, on my car doesn't work. It used to but now only operates on side lights.

Any ideas please?

Mine stopped working and behaved like yours, but then I'd turned on Coming Home Lights which explained it.

Another idea might be the microswitch in the driver's door which may have failed, but unlikely as the side light buzzer still works. Do the interior lights and door open symbol on the dash come on when you open the door?

Mine works like that now I have CHL activated. But when I first got the car the still only worked on sidelights, if I removedcthe key from the ignition with the headlights on, the headlights just went out, so no need for the warning buzzer.
