I have a loaded 2004 645ci convertible w/SMG & the headlights that turn with the direction you're headed. The headlights spontaneously and simultaneously stopped working. I get an error light on the dash when I try to turn them on. They don't work. Running lights work fine/side markers/halos/high beams.. everything works. It's just as if the primary headlights stopped working.
Basically I need some help diagnosing this please and what part I exactly need so that I can look it up.. or if someone knows of the part and knows a great price then that would be fabulous too!
I don't want to sound redundant here, but obviously people ask a lot of questions so i'd like to nip what i can in the bud. Yes there was some condensation in both of the lenses prior to them failing and now. Before they finally failed the headlight LED to indicate that they're on would flash when the headlights were on. At that time I noticed that they wouldn't swivel with my vehicle when it would turn, but they were working at that time. Then finally they just stopped working when i tried to turn them on, and obviously there's a notification saying something like "beam malfunction."
I don't have a diagnosis computer and visiting a dealership is not an option. Also there aren't many helpful independent service shops. Supply is low here in Buffalo so prices are high.
I'd like to address this myself. I've heard something like "actuator" needs to be replaced. I need a little more specificity please so that i'm aimed in a more specific direction.
Thank you very much. I can be reached through this thread or via call or text at 312-885-9023. My name is Scott. Thank you.
