Hi Had Airbag light problem. Fed up of getting garage to clear it. So brought cheap cable and downloaded vcds. I made sure went for dumb cable one. Any way it won't work. Windows 8 laptop and 03 a3. Says port fine can't connect. Tried on 3 and then on 1. Nearly gave up then found Vag com 409.1 download. So download that. It crashed at first so tried in X compatability mode. Worked straight away. Went on Airbag module and cleared fault. Any way so point is why can't I get vcds working.
