I recently removed old xenon lights and changed to LED rings instead.
Now the left eyebrow does not work at all. I have triplechecked all cables after installing and nothing seems out of place..

Tried googling, but no results for this problem. Anyone got some tips?

 

The eyebrow light has a separate conector to the cars wiring harness. The large conector controls headlights, turnsignals, adaptive lights. A smaller plug, 2 wires, controls the eyebrow. Did you get it plunged back in? Both of these connectors are located behind the light assembly.

 

These? They are pretty firm and don't seem loose. I will remove the headlight today and check it again. I'll update this post later.

 

No, when you had/have the light assembly out of the car, there are 2 wireing connectors to the cars wireing harness. The large connector, which handles all light functions, less the eyebrow and a second smaller connector, which is for the eyebrow only. Both connectors are located on the backside of the light assembly. I'm assuming you removed both headlight assemblies when you upgraded the angle eyes.

 

I swear I have no explanation for this.
Stopped at a gas station to fill up my tires. After that it suddently worked - I did not touch the wiring since I last posted.

It's in perfect condition now. Thank you for your help

 

You're welcome. That was me that did that.

 

More power to the fix. Much better than a expensive, time consuming repair.

 

This reminds me of a friend's e46 318i. the 8 and i had fallen off the rear badge. One day he woke up to go to work and found the somebody had perfectly installed his missing 8 and i.. Was that you too?

 

yep! i totally remember doing that. i also left a dollar under his pillow, tell him he still owes me a tooth.

 

Do you mind fixing it again? It just stopped working.. you have a grudge against me now?
