Hi, I brought VAG hardware to re-program a new key for my Audi 80 1995 2.5 v6. When I follow the instructions of ross-tech page where it states to login and enter a new value of 0 the program returns 'login lost due to dropped session'. when I go into adaption and try to chage any values it return 'ERROR'. What is actually the problem here? Is my 4-pin Audi code incorrect? Or is it something else? Any help would be great. Thank you in advance. Acer.
