I'm a little confused with all this. I think the cable I need for my car is the HEX-CAN.usb interface with the latest software (805?). The car is a 2004 (54), A4 B6. Does anyone know if this is definately the correct version I need or is my car too old for this version? Also has everyone bought directly from Ross-tech? Is this the safest way, I'm thinking warranty on hardware, etc? As they're across the pond, do you end up with import duties to pay? Or is it best to buy from one of their distibutors like http://www.ilexa.co.uk/ ? I've also heard of people buying other leads and then upgrading from the shareware version to the fully registered version for around £70. This 'sounds' like a cheaper alternative, but is it legit, pose any problems etc. Also is it simple to use? I initially want to check EGR, MAP and MAF as well as VNT actuator (as I'm overboosting causing limp mode). After that, I'm thinking about some of the cooler codings you can do with it. Thanks in advance.
