Although I do not own an Audi, I have a 53 plate Leon Cupra 180.
I have just bitten the bullet and bought the fully licensed VAG-COM cable so I am keen to find out any issues that I may need to know when fault finding etc.
Cars I have already been assigned to are a 2000 RS4 B5 Avante, A3 1.8T 150 and a 2000 TT 225. - So its started already!!
