Folks, I have a mk3 Superb and an old OBD2 reader that connects to my laptop. When I plug it in the light stays red and the software comes back as can not read.. 

Any recommendations for a new reader or software compatible with Skoda.. ?? Got a light on exhaust issue.., but when a guy I know plugged his laptop in to clear it the fault showed as a heating plug issue, would like to be able to read it myself like I could on my Mondeos.
