Hi. In the next few days i'm going to look at a 2009, Audi A3, S-Line Black Edition, 2.0TDi 3 door & i am not very familiar with these models. Can anyone give me a general idea of what to look out for when purchasing this particular car? Common faults, noises, vehicle history (parts replaced), improper wear & tear (uneven tyre wear), etc. I have V.C.D.S. so i should be able to plug that in for a start & that should tell me of any logged in fault codes on the CANBUS system. Any help, advice or info from any S-Line black edition owners would be extremely appreciated.
