I have a software VAG 1551 and I am trying to figure out which blocks mean what. I am not talking about error code output, rather within the 1551 I see that block 0 is active. I see 10 output values that range from 0 to 255 on my '91 200. I want to know what each of these 10 values stand for. Anybody have any clue? Thanks, Wolff
