I have a genuine KII lead from RossTech, and have used it on my B5s quite happily for a good while now. I have also scanned a couple of mates non-VAG cars using the OBDII screen - again no problem. (One was a 1999 Bentley Arnage, the other a 2002 Ka using 11.xx.xx VCDS) However, I tried to scan a 2004 Ford Fiesta yesterday, and could not communicate with it. I had the same trouble with a 2006 Passat - but suspected the KII interface would not read the HEX on the newer models. Is there the same issue with ODBII using hex and thus I'll need the newer lead? (Stop rubbing your hands Nigel - I'll let you know when I want to upgrade :icon_thumright or has the newer 12.xx.xx VCDS less compatibility?
