BMW i4 Headlight Range Control Malfunction Fix Needed

I feel your pain with those headlight issues. Had a similar problem with my 2018 BMW iX3 last summer. After getting that same warning light and alignment problems, it turned out to be a defective servomotor in the headlight assembly. The repair wasn't particularly complicated, but it needed proper diagnostic equipment to identify the exact fault. My mechanic had to replace the servomotor unit and recalibrate the headlight control system. The whole job took about three hours, and while it wasn't cheap, it wasn't a serious mechanical issue. Just make sure you get it checked out by someone who knows their way around electric BMWs, these adaptive headlight systems are pretty sophisticated and need proper diagnostic tools to fix them right. I'd suggest going to a certified BMW specialist who has experience with electric models. After the fix, my headlights have been working perfectly. No more warning lights or alignment issues since then.

Thanks for sharing your experience! That's really helpful to know it was the servomotor. My symptoms sound exactly the same as what you described. By any chance, do you remember roughly how much you ended up paying for the repair? And has everything stayed working properly since the fix?

Hey there! Happy to help with more details. Yes, everything has been working perfectly since I had it fixed. I actually got it sorted last week, paid 1040 € to replace that faulty servomotor in the headlight. Might sound a bit steep, but honestly, it was worth every penny to get it done right. The headlight range control is working flawlessly now, no more warning lights or alignment issues at all. I was pretty relieved it was just the servomotor and nothing more serious. The BMW specialist I used knew exactly what they were doing, and they sorted it out in one go. Trust me, if you're seeing the same symptoms I had, getting it fixed sooner rather than later is the way to go. These modern headlight systems are quite complex, but once they're properly repaired, they work like a charm!

Just wanted to follow up and let you know I got my headlight issue sorted out yesterday! You were spot on about everything. Took it to a BMW specialist and, sure enough, it was the servomotor causing all the trouble. Ended up costing me about 1100 €, pretty close to what you paid. The whole experience wasn't nearly as painful as I'd feared. The mechanic was great, really knew their stuff with these electric models. Got my car back same day, and the difference is like night and day (pun intended!). The headlights are perfectly aligned now, warning light's gone, and everything's working exactly as it should. Really appreciate you sharing your experience, it helped me know what to expect and gave me confidence to get it sorted. Sometimes it's just good to hear from someone who's been through the same thing. Thanks again for the help!
