hi first of all I want to thank you for the video, it is very well explained. On the other hand, I had a crash and I have AFS in my car, but I got a non-AFS that is aesthetically the same, can I make it work? If you can explain to me how to make the form, I will do it. I am from Argentina and it is difficult for me to receive an adapter from another country.
Thanks , i really needed this video to understand differences , many thanks
Glad it was helpful!
Wow, thanks for the video is really educating me.
Can I swap my normal halogen lights to the projector xenon lights and what are advantages and disadvantages? Thanks
Yes you can, but you will need at least adapter cables. It is NOT a direct swap. You have to be ready for additional work and a bit headache.
Hi XenonLand. I have a freshly refurbished headlights on my B7 for 1 year now. In the Audi dealer they had to remove the front bumper. Ever since they reinstalled the bumper I have moister issue on my headlights. One of the headlights was cracked and now I ordered a new one, but last night I saw a little moister on the other headlight. Do you think it's possible to have moister coming from the ballast, maybe the rubber seal needs adjustment? The moister is coming from the inner bottom edge of the headlight.
If the rubber seal is not deformed/damaged it is very unlikely to be the source of the condensation. There is always some kind of a damage on the headlight case or the lens itself. Just needs to be inspect carefully. Even a small crack around the mounting points is enough to prevent the headlight from "breathing" properly.
@@xenonland make sense but both lens of the headlights are brand new 😔
Most of the time (almost 99%) it does not have anything to do with the lens! If there is a crack at the lens you can easily see it. Most of the time damage/source of the condensation is on the headlight casing. Watch this video (part-2 will be uploaded in 1-2 hours): ruclips.net/video/BM9doXUsgKw/видео.html
Also, I understand that you can’t swap ballasts between adaptive and non adaptive headlights, but can you replace the entire adaptive headlamp assembly with a non adaptive assembly?
Yes you can't swap ballasts from non-afs to afs headlights, they are different physically. Yes you can put non-adaptive ones but you might need adapter cables and resistors in order not to have an error at your dashboard.
@@xenonlandcan i swap a ballast afs to a none? I change the headlight
This was a very useful video. You likely saved me some costly mistakes. Will you make a video on troubleshooting dipped light errors? My son has. 2006 Audi a4 b7 with a dipped headlight error. He has adaptive headlights. We can see the driver side headlight do a start up test when car starts but not the right side(it does nothing). Also his headlights are very dim
