The issue is your headlight control unit isn't coded to the car, so your car 'thinks' that there isn't a headlight there. I'm assuming you have xenon's that came on the F30.

Yeah that's what i originally thought too that's why I downloaded ista p, but when I ran the diagnostic it actually came back as a short circuit. Also the unit was tested on the other side before installing and it worked perfectly so I'm thinking it may actually be a wiring issue also both headlights are halogen, but thank you for the info and I'm actively seeking someone to install a new wiring harness to see if that helps
