I'll start with that I have a 96 A4Q.

Suddenly, my driver's side corner light will illuminate when I depress the brake. I have no idea what's causing this. I didn't fu(k with it, it just happened randomly.

I'm not sure where to start diagnosing this because I've never encountered this kind of problem unless I was ******* with one of my friends...but I added wiring for **** like that. IE: Wiring the brake light switch up to the horn, like that video with the guy in the talon.

 

its an electrical nightmare.....

 

Check the ground connections.

 

just wire the other side so it will match.

 

Tomorrow I'll dive in and murder those little gremlins...

But if I can't find it, Kelly had my next idea, that or make day running lights. I don't want to but I will if I have to.
