Picked up a set of Adaptive Bi-Xenons (Non DRL) and in the process of fitting them to my 2005 A3 Sportback. When I bought them I naively thought they were plug and play. I am at the point where I need the adapters but want to check if I am getting the correct thing. Audi A3 8P + TT 8J Xenon headlights adapter cable set, suitable for Bi Xenon | eBay Also reading a few threads it mentions wiring back to central electronics module, but to where exactly? Also what needs to be done on VCDS. Finally, to be right I should fit headlight washers, how much work is this and what would I need. Thanks in advance.
