Afternoon all. I'm new to the forum and was just wondering if anyone on here has experience of using a handheld code scanner on an Audi A5 3.0TDi Quattro? I recently bought one that was suppose to work with any OBDII connector for any VW or Audi from 1996 onwards. It works fine on our 2000 1.8T TT but not the A5. I've read in a couple of places that this is because one is a diesel and the other a petrol and it only works with petrol which clearly doesn't seem right to me! If anyone on here has knowledge of what works for their A5 3.0TDi I'd love to hear back please.
