    Try checking the switch... make sure it's still functioning. After that, wiring is your only option. Doesn't seem likely though. You could also test the fuse connector with a multi-meter and see if any volts are coming through, check the light connectors and see if volts are registering.... I'm thinking the problem could be between the switch and the fuse box but I am not sure....

    Does this include the turn signals / hazards? If so, it can't be the light switch.
    The left and right head lights have separate power sources (SSP relays and fuses).
    The FEM controls all the front lighting. Do the interior lights work? They are also controlled by the FEM.

    I checked the voltage on the headlight plug with a multimeter it says 12.2 volts and I replaced my headlight switch a couple months ago

    The SSP relays provide battery power to the headlights all the time that the car is awake. The FEM grounds the other side of the sockets when the head lights should be on.
    Maybe you have a partial failure of the FEM, or maybe some power grounds to it are open for some reason. If you have Forscan, it would be really good to see what the FEM is reporting.

    As I said, there's no way the headlight switch would have stopped the turn signals from working.
    The cluster reads the headlight switch, the light sensor, and the turn signal switch, and then reports that to the FEM. So it is possible that this could be a problem with the cluster instead of the FEM. If you turn the headlight switch on, do the instrument lights come on? Does the cluster seem to be working correctly? Do the rear turn signals and hazards work? If not, maybe it is the cluster. If so, then it points more to the FEM.

      I'd be much more concerned about that Low Oil Pressure light

        And that has little to do with low/no oil pressure!
        Does the light go off above idle?
