Im looking to get a cable for my laptop so i can scan the car before i buy it! However... theres soo many cables on ebay and most say not available for the A3 8P and are unsure which one to buy. Is there a specific version number i need to buy? I know i need the VCDS Lite version to go with it rather than a full version. If someone can put me in the right direction i would be really appreciative. I went to see a car today and it has a engine warning light on and the guy said it was the exhaust, and it would be helpful if i could come prepared in future to check the problem myself. (i would of bought it anyway but the guy didnt have the V5 document so walked away). i can test it out on my dads dirty branded VW golf right? Thanks in advance for help! JJ.
