I was in a wreck and I had to get my passenger side headlight replaced on my 2015 328i. The headlight is the same type as the one that was damaged I have ista + , a obd / enet cable and wifi connection.

Update:
So I just ran a diag using ista
and I got these faults:

804193 SIDE LIGHT R
804195 LOW BEAM R
804197 DAYTIME R
80419B HIGH BEAM R
80419D TURN INDICATOR R
804872 BRAKE LIGHT L

Apparently there is short circuit any fixes???

Do you still have the old headlight? Is the original control unit still attached and undamaged?

Unfortunately no the whole unit had to be replaced
-side note I checked all the associated fuses hood trunk and passenger side and they seem to be fine in addition the headlight and components are the same as the one that was damaged the new headlight was tested on the driver side and was fully functional

If the control unit on the headlight was also replaced, it needs to be coded. If you're not comfortable with coding control units on your car, try to find someone local to you that is or bite the bullet and pay the dealer. I've only ever coded with NCSExpert on older models, so I won't be able to walk you through it on the F30. 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

If you've ruled out the control unit then yes, you have something else going on. Most people don't realize headlight control units are VIN specific but it sounds like you confirmed the control unit is good. Good luck, hope you get it resolved.

The need to code a headlight is a perfect example of German over-engineering.
