See my signature - I've got a 193 working in my 2006 B7 RS4.what year does that work for? an would i be able too get one of the new ones too work in my B6 2003 audi a4??
Things that don't work:
- speed limit display (needs messages on the Infotainment CAN that the B6/B7 don't have).
- RS4 startup screen (not in the new software)
It should work just as well in your 2003 B6 A4.
