...moisture problem after fighting with Audi dealer and Audi NA. I am going back and forth for over a year, on and off. I did the O-ring fix that is an almost every forum out there. Additionally, put my own touch on this. See pictures. I have tested it before posting, it been a week and one major rain. Yes, little fogging accurred, as Audi says it is normal. Before the mod, it wasn't normal, see pictures, I was never able to burn that off with my headlights on. I had little fogging on the bottom on night for an hour or so. I guess the weather was just too humid and what ever. It went away as quick as it came. They are vented, each headlight as two vents, for what I could see. Which fogging can naturally occur. Enjoy the pics. Sorry for the last one, it's a cell phone pic.

I did some night pictures, it was horrible to drive at night with those..
Before pics...











After pics...








And the Ronny touch, since the o-ring alone is not 100% proof for me. I did use silicone, I can remove this without any trace that this was ever covered.



Thanks. This post is for those fighting with moisture in their headlights. Who came up with the idea to place this in the open where water can dripp on every down pour?
