So I've had my headlights replaced cause one went out, and it worked for about a week before the driver side headlight got condensed inside. Week later bulbs no longer worked, and iDrive tells me adaptive headlight failure on driver side.

I bought a replacement xenon headlight ballast, correct me if I'm wrong, I just realized there's also an adaptive headlight ballast. I feel I bought the wrong one, but is there a way I can diagnose it before ripping off my headlight assembly?

Anyone have a DIY to replace either of them?

2007 e92 white, driver side headlights don't work, adaptive headlight error on idrive.

MORE THEN LIKELY the cover was not installed correctly and the control unit
at the bottom is swimming in water. remove headlamp and or wheel well lining
and inspect.

i second this.

if you are handy and like having fun on your free time, pull the front bumper cover off (easier than it sounds) and remove the headlight assembly to dry it out.

Thanks for the responses, I've had a mechanic dry it out, but one of the ballasts are fried. Sometimes on iDrive I see left low-beam malfunction, and sometimes I see Adaptive Headlights failure,

you guys think it's hid ballast or adaptive headlight ballast that's fried?
