Automatic Headlights DRL Issue

artem · 12-21-2016, 01:18 AM

First of all, I would like to say hello as I am a new forum member.

I got my 2010 40th Anniversary Z two months ago.

I always keep my headlights in the "Auto" position, so a few weeks back I noticed that the driver side headlight did not go on. This is fixed by flicking the switch to Off and back to Auto again.
This started to happen frequently, and mostly (only?) during the night time. If I do not fix this issue right away and I notice it after I have been driving with only the right headlight on, the only way to fix it is to restart the car.

Stealership wants $130 for diagnostics. They mentioned it might be related to the DRL module.
I did replace the stock bulbs for 6000k ones before the issue started, so my first thought was the ballast was loose, which it kind of was. Regardless, I made sure the ballast is 100% on and the issue still persists. Thoughts?
