A friend wants to code in rear LED lights and i'm wanting to know which option to tick. I have full VCDS and went to byte 18 in Central electronics, went through to the long coding helper and its given me a long list of cars to choose. I chose the Golf GTI option because I'm fitting them into a GTI and chose the RoW option and it coded in. But i'm still getting an error on my dash for rear fog. Anything else I need to do? Or do I need to choose another option. Any help guys?
