So I got the K+D Can cable and it does now see the "ignition on" I still get a CAN bus communication error though (I'm thinking it's a cable issue) and I can't seem to get the service functions working in DIS ;( I played around a bit with INPA and that seemed to work fine (but in German) but I think I reset the Readiness monitor and now my check engine light is on with no DME codes! I'm thinking the light will go out when the drive cycle is completed ?? We don't do much with emissions testing here so I have no experience with how that works.
