Basically bought an Audi s3 with only the spare key and was looking at information about the skc, this seems to be the only DECENT site with information, and as my wife has a Mk4 TDI as well I think I'll be using it more as there seems to be a lot of good information available.

Thanks

Welcome!

The year of Audi S3 matters because I believe your mk4 should use a kii diagnostics (not 100% sure since Europe got CAN BUS earlier than the US), and the newer years don't work with vag commander.
