Hi - I have searched threads and read some differning opinions on this subject but I have just purchased a 55 3.0tdi avant S-Line as the family bus and am very pleased with it but, to my suprise, when driving home I realised that it did not have a trip computer (DIS) - All I want to be able to do is see the MPG. Would someone kindly just confirm that on this Model & year of Car all I have to do is fit the correct wiper stalk and have it recoded, where would I go to get this done? Any help and advice much appreciated - Thanks - Curlyred (55 3.0 A4Avant TDI S-Line Quattro)
