Hey all,
first time poster here.
I recently purchased a 2001 A6 2.7T (manual trans)

I have a couple questions.
My third brake light (high mount) has some bulbs that went out. I want to replace with an aftermarket led brake light.
Will doing this turn off the brake light warning light on the dash.

Also, for some reason when I turn on my headlights, the abs and traction control lights come on. Is this related to the brake light being out?

And finally, How do you turn off the airbag light on the dash?
any help would be greatly appreciated!!
