Good question and something we are currently working towards reviewing..
We have on loan an OBDII reader package but initial results have proved unsuccesfull ( non compliance of engine sensors to the current cable )
Software tested was digimoto.
We are awaiting and alternative cable and will report our findings on the home page when testiong is complete.
If do perform a search of this forum using the phrase "OBD" you should find the main post on this subject.
Hope this helps
Dave is the
stuff your thinking of the dialogy's software ?
This is a useful purchase but more like a vague how to version of a haynes manual as opposed to realtime
fault code reader / diag kit..
