E92 headlights dont work..what did I miss?

So I pulled off the bumper, replaced all the lights and still the same thing...only the halos light up and turn signals work just as before....all new bulbs same as original yet same issue...failed my inspection...Nice little Red R.....cant even drive the car now or I may get a ticket....

A green light on my headlight switch flashes which tells me I have a problem with the headlights which I know that much and the nav screen also tells me the lights are out but what is it?

I ordered a new headlight switch and checked the fuses they seems to be ok, could it be the ballasts or is it something I over looked?

Welcome to Bimmerfest!

Do you have a wiring diagram? Do your headlights go to high beam? Can you flash your highbeams with the stalk? Actually you are in luck, having both headlights out is a lot easier to diagnose than if one is out. Strange but true. My guess is that you have a switch problem but that's a WAG at this point.

The green light blinking means there is a fault with the adaptive system.

Forget the green light/adaptive system for now.

Why did the lights stop working? Out of nowhere? After an accident?

If it was after an accident, your FRM is most likely storing short circuit faults. These faults disable the circuits until the counter is reset and faults are cleared.

You need Toolset32 to reset the short circuit counters.

I was hoping it was something more simple like a ballast lol.

I got the new headlight switch in, installed it to no avail, same thing. The green light only flashes in the AUTO setting, when i toggle to any other it turns off.

The car is clean title and I haven't had an accident with it, I checked the frame and it doesnt appear it had a collision.

Toolset, never heard of it. I assume its an interface for a laptop and the car? Gonna research it a bit more, things sure are getting more complex by the minute.

The green light is only suppose to come on with Auto mode. It's the indicator that the adaptive system is working correctly. Solid means everything is functioning properly. No light means the system is off. Blinking means there is an issue with the system.

Inspect the drain gates under the hood by the struts. Clogged with leaves? Clean the grate out. When this grate is clogged, it allows water to overflow into the cabin, right on top of the FRM module which controls lighting and windows in the car.

No clog?....check the headlight seals. If one of them is bad, especially one of the upper seals, water will pool on top of the SMC II module which controls the adaptive stepper motors in the headlight. This is a very common issue on E9x chassis'

Refer to the coding section for more info on Toolset32. It's a program included in the BMW Standards tools package used for vehicle coding, programming, and diagnosis. Available free if you look online but the cable is about $100 from onestopelectronics.com

My bet is you need a new FRM module. If you have an early build, you can take this opportunity to upgrade to FRM3, which is the latest revision of FRM. If you have FRM1, this upgrade will give you Welcome Lighting and a few other features as well as more options for custom coding.

Been a busy week but I did as you suggested, flood gates are clean and now that you mention it I remember some condensation in the drivers side headlight a few weeks back, that could have done it so I ordered 2 ballasts and plan on installing them this weekend, if that doesn't do it then I was thinking going to BMW and have them re-program the lighting module. Hopefully thats not shot too...Once I can get these lights to work I can pass inspection. I was also thinking of buying the interface cable and snooping around with the laptop to see what comes up.

Before even installing those, you should get a multimeter and check if there is voltage at the headlight harness.

If there is no voltage at the harness, check fuses. If they are good, see if you can see any damage in the wiring harness. Check grounds

Then all that's left is the FRM module.

I would just keep ordering stuff and proceed with trial and error. Proper diagnostics is overrated.

Great advice. That seems like the most efficient way to get this done.

I installed the new ballasts today and "taaa-daaa." Worked like a charm. Old ones were white, looked like they had baking soda inside...for the hell of it i also checked the nearby board next to the ballasts, called the ACL module.not sure exactly what it does but my quick guess is that it controls the adaptive headlights??? One was good and the other moldy. I used rain-x for all the rubber seals so hopefully its tight now. No more error other than adaptive headlight warning...now i can pass inspection....Thanks so much everyone for all the help and ideas, I am very grateful to you all for your time in helping me fix my issue
