Does anybody know if vagcom for my 4x4 also works on a A4 tdi and a S3, both from around 99 - 2000. Wasn't sure if you would need different leads or version. If they are the same might be able to share cost with a couple of blokes at work:)

I would think Same lead - no problems. The only oddity might be one has a 2+2 connector which still requires a standard lead anyway.

My HEX+CAN-USB lead works fine with my son's 2000 Audi S3 which has a standard diagnostic port.

Thanks for that - just have to persuade the others to part with hard earned!
