just bought an s3 and im interested in purchasing some sort of vag cable.
its a 2002 51 plate s3 so i dont need a cable that suits new VAG's.
From what ive read, you need a cable and the software downloaded to a laptop.
What kind of price are you looking at for the cheapest cable and a free old software version?
Is there a medium price cable and an expensive one too?
What are the benifits in buying an expensive cable and wuld i ever need the extra functionality?
Where do u plug the cable in?
"Cheapest" may be cheap, but it is quite possible you will pay in the coin of frustration before you actually get anything to work.
Medium = KEY Series
Expensive = HEX+CAN Series.
