Well, I followed the coding within the FAQ, but can only assume this is for a pre facelift? When the DRL's were on, the Xenons were on at the same time, put the coding back, all back to as was. Do I need the repair wire? Has only got the coming home lights working with DRL's? Are you also able to have the sidelights as DRL's not reduced in brightness? Answer below I think to this question http://www.audi-sport.net/vb/a3-s3-...-drls-vcds-mod-3-dr-facelift-a3-s3s-only.html We also , changed the coding within the convenience menu, we enabled sunroof/windows by remote, but it does not work? Coding on my previous Golf was easy, and it worked. I also wanted the rear lights on with the DRL's, I'm guessing this is possible? Is there a definitive guide to coding?
